Compile Error #3798

daqingsu19 · 2021-02-12T20:01:01Z

[x ] I've asked for help in the Truffle Gitter before filing this issue.

I wanted to try out Truffle/Ganache. So I followed

https://ethereum.org/en/developers/tutorials/create-and-deploy-a-defi-app/

-I am having version issues with Truffle. This is what "truffle version" shows:
Truffle v5.1.66 (core: 5.1.66)
Solidity - 0.7.4 (solc-js)
Node v15.5.1
Web3.js v1.2.9
I specified solc 0.7.4 in truffle-config.js because the openzeppelin that I use asks for pragma between 0.6 and 0.8.
I specified "pragma solidity >=0.4.22 <0.9.0;" in my contracts. But when I do "truffle compile", I got this:

Compiling your contracts...
✔ Fetching solc version list from solc-bin. Attempt #1
✔ Downloading compiler. Attempt #1.
TypeError: Cannot read property 'imports' of undefined
at Object. (/usr/local/lib/node_modules/truffle/build/webpack:/packages/compile-common/dist/src/profiler/requiredSources.js:98:1)

Truffle v5.1.66 (core: 5.1.66)
Node v15.5.1

Seems like I am not able to make truffle, solidity, and openzeppelin all happy wrt versions.

I also have the same problem

xternet · 2021-02-13T16:21:46Z

Downgrade truffle to: 5.1.65
Set contracts and truffle-config.js solc version to: >=0.6.0 <0.8.0

daqingsu19 · 2021-02-13T17:52:54Z

Downgrade truffle to: 5.1.65
Set contracts and truffle-config.js solc version to: >=0.6.0 <0.8.0

Yes downgrading to 5.1.65 works. Thanks a lot!

Thank you sooooo much!😀

zacel · 2021-02-13T21:43:52Z

Thank you for this solution but why did you close the issue? it seems like if downgrading to a older version is the fix then it should still be open because it's still broken in 5.1.66 which is what new people will install by default

khushjammu · 2021-02-14T05:19:58Z

I'm having a similar issue. The initial build of my contracts works fine (when artifacts folder is empty). However, every subsequent time I try to truffle compile, I get a weird error.

have you found any solution to this?

zacel · 2021-02-15T17:53:47Z

I have been getting the same error and found 2 solutions. First is to use a older solidity version (it works for me with 0.6.6) or to use a different tool then truffle (like hardhat)

I tried with Truffle v5.1.65 (core: 5.1.65) and Solc 0.6.6, but nothing works🤯

zacel · 2021-02-15T19:25:57Z

for me I had to delete truffle globally, delete node_modules in my project and then after reinstalling everything it worked

sofianeOuafir · 2021-02-15T21:22:29Z

downgrading to 5.1.65 worked for me. curious to know why 5.1.66 didn't work

jha-prateek · 2021-02-16T04:55:33Z

truffle compile --all

This works

Eliseowzy · 2021-02-16T17:17:05Z

Actually, I came to this trouble when I was testing my project, when I tried the command truffle test it just showed off this error:

Compiling your contracts...
===========================
TypeError: Cannot read property 'imports' of undefined...

I reinstalled Truffle: npm install –g truffle@~5.1.65
The OS of my device is Windows 10, and truffle, solidity and node.js versions are as follows:

Truffle v5.1.65 (core: 5.1.65)
Solidity v0.5.16 (solc-js)
Node v12.16.1

Then I declared pragma solidity ^0.5.16; at the begining of every contract. I also modified the fruffle-config.js file of the project into:

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // for more about customizing your Truffle configuration!
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "*" // Match any network id
    },
    develop: {
      port: 8545
    }
  },
  compilers: { //I added this parameter.
    solc: {
      version: "0.5.16"
    }
  }
};

Then under the project root directory(project_name/): I tried the commandtruffle test again, it worked for me.

ehildenb · 2021-02-16T17:44:33Z

Downgrading to truffle@5.1.65 worked for me. npm install truffle@5.1.65

snwokenk · 2021-02-16T21:34:44Z

@jha-prateek answer of using "truffle compile --all" worked for me.

It seems most are making changes or adding new contracts and forgetting to recompile

haltman-at · 2021-02-16T23:18:07Z

OK, it seems a lot of people are having this problem. Does anyone have a reproduction example we could check out? Otherwise I'll attemtp to reproduce this myself, but I'm hoping someone has an example I can use directly. Thank you!

haltman-at · 2021-02-16T23:21:23Z

I have a suspicion that PR #3802 might fix this problem. However, I really need a reproduction example to be able to check...

sshmaxime · 2021-02-17T02:13:48Z

Try to delete your build folder, it worked for me.

ehildenb · 2021-02-17T20:19:11Z

@haltman-at

Reproduction:

git clone 'https://github.com/runtimeverification/firefly-demo'
cd firefly-demo
git checkout f6c72e0
npm install
npm install ganache-cli

In one terminal:

./node_modules/.bin/ganache-cli -p 8145

In another terminal:

./node_modules/.bin/truffle test

Results in this error:

Downgrading to 5.1.65 and the error goes away and tests run successfully.

I'm on Node 10.23.0, if it matters.

haltman-at · 2021-02-18T01:14:04Z

@ehildenb Thanks! I'll check it out.

haltman-at · 2021-02-18T01:49:40Z

Hm, I can't seem to reproduce this at the moment. I'll have to try some more combinations later, I guess. That said, I have a suspicion that #3802 might fix this anyway...

jha-prateek · 2021-02-18T05:04:11Z

@jha-prateek answer of using "truffle compile --all" worked for me.

It seems most are making changes or adding new contracts and forgetting to recompile

Yes, but it's strange because truffle compile should work even without using --all flag. Truffle docs says --all: Compile all contracts instead of only the contracts changed since last compile.

jha-prateek · 2021-02-18T05:06:33Z

Hm, I can't seem to reproduce this at the moment. I'll have to try some more combinations later, I guess. That said, I have a suspicion that #3802 might fix this anyway...

Can you check, how truffle compile --all is working and not truffle compile. This might help you in finding the problem. 😀

haltman-at · 2021-02-18T05:46:41Z

Ah, good point. I'd been compiling from scratch. But, the example given by @ehildenb above also involves compiling from scratch. So that doesn't help. Does anyone have a more specific reproduction example I could try, including which contracts to compile in what order?

soohanpark · 2021-03-31T01:59:21Z

Try to delete your build folder, it worked for me.

Cool, It's work for me :)

I am still hitting the same error after attempt with Truffle 5.1.66 and solc 0.8.0.

I tried downgrading truffle to 5.1.65 and using Node 10.23.0, it returns me the same error.

I tried with the latest truffle version seems like the issue still persists.

Yup. I deleted and recompile the folder and test it each time I use a different version.. but hit into this error (with different version denote below) when i run truffle test... anyone hit the same issue as per mine?

haltman-at · 2021-04-05T18:54:49Z

@lawrenceCP Are you still getting the error with Truffle 5.3.0? Could you confirm that? Thank you!

@Soohan-Park To be clear, deleting the build folder (or just using truffle compile --all, which I think would be easier) is a workaround; it's not something we want people to have to do! If the error is occurring, we want a clear reproducible example so that we can fix it, not for people to just resort to deleting their build folder!

lawrenceCP · 2021-04-06T15:47:49Z

@haltman-at yes, after tried delete the build folder (or run truffle compile --all) then run truffle test. I am still hitting the error with Truffle 5.3.0.

haltman-at · 2021-04-06T17:07:44Z

@lawrenceCP OK, do you have some sort of reproduction example I could check out to figure out what's going on? Thanks! (I'll reopen the issue.)

We currently support Node 10, Node 12, and Node 14, although we may be dropping support for Node 10 in a few months.

lawrenceCP · 2021-04-07T16:02:05Z

@haltman-at lets try this:

git clone https://github.com/lawrenceCP/testTruffle.git
cd testTruffle
truffle compile --all
truffle test

Then you should be able to get an error similar to this.

Node v14.16.0

eggplantzzz · 2021-04-08T16:34:05Z

To provide another data point here, @lawrenceCP I cloned your repo and had to fix a couple of imports. In TestAdoption.sol you had import "truffle/Deployment.sol where it should have been import/DeployedAddresses.sol. I also had to correct assert.equal to Assert.equal. After this truffle test ran without any errors. I ran it with Truffle 5.3.0 using both Node 10, 12, and 14.

Is it possible that you have other files in your repo that are not being committed or something? If you do a fresh clone and complete the steps you listed do you still get the error?

lawrenceCP · 2021-04-08T17:09:11Z

@eggplantzzz Thanks for the tips. After changing the import statement from import "truffle/Deployment.sol to import "truffle/DeployedAddresses.sol"

as well as the Assert.equal statement, I managed to run truffle test without errors.

@haltman-at may proceed to close off this issue. Thanks.

haltman-at · 2021-04-08T20:18:06Z

@eggplantzzz I don't think that resolves this issue. Truffle shoud not produce errors, regardless of whether their imports are correct or not. If they have incorrect imports, they should see a compile error, not a Truffle error!

joequant · 2021-04-09T09:52:02Z

FYI. I'm stil seeing the issue, but it's happening less than before, and seems to go away if I delete the build directory.

@haltman-at I didn't say it solves the original issue by the original poster. I am merely saying that after correcting the errors I listed, I am able to run truffle test without any errors: parser errors, compiler errors, or otherwise. When I first cloned the repo, there were a couple of issues with the contract that needed to be fixed (as I noted above).

staringispolite · 2021-04-11T20:04:35Z

I got this same error for a seemingly unrelated problem: I was missing a } in the newest contract I had just added

deleted /build
ran truffle compile --all
got me a slightly more helpful error: "FILENAME_HERE.sol:LAST_LINE_OF_FILE:1: ParserError: Function, variable, struct or modifier declaration expected."

realized/fixed the mistake
ran truffle compile --all
compiled successfully

MatthewDHarrison · 2021-04-16T01:40:12Z

I had this error too, got the undefined imports message only when running "truffle test" but not "truffle compile".
What worked for me:

deleting build folder
downgrading from v5.1.67 to v5.1.65
making sure import statements were correct (i.e. "truffle/Assert.sol" instead of "truffle/assert.sol")

The version of solidity didn't seem to matter, got it to work with 0.5.16 and >=0.8.0

haltman-at · 2021-04-19T21:12:37Z

@lawrenceCP OK, I have successfully reproduced the error! Thanks so much for the example, sorry for taking so long to get back to this; I've had my hands pretty full. But now I can look into what's causing this and hopefully fix it.

gideongrinberg · 2021-04-22T02:02:46Z

This is still broken on the latest version and 0.5.15. Getting truffle to work with solc has just been painful.

haltman-at · 2021-04-22T03:06:36Z

@gideongrinberg A fix for this (or what should be a fix for this) will go out with this week's release!

@gideongrinberg A fix for this (or what should be a fix for this) will go out with this week's release!

@haltman-at is there any temporary fix?

haltman-at · 2021-04-23T17:37:25Z

Well, as other commenters have mentioned, the error doesn't occur when recompiling the whole project. But, if you can wait just a few hours a proper fix should go out in today's release, as mentioned, so any temporary workaround will be quite temporary indeed. :)

haltman-at · 2021-04-24T00:55:42Z

The fix for this should be out now, so I'm closing this once again. If anyone sees this again, please let us know and we'll reopen it a third time.

sjschweber · 2021-05-29T21:00:33Z

Hey, I am getting this error even with most recent version of truffle ...

Error: Truffle is currently using solc >=0.6.0 <0.8.0, but one or more of your contracts specify "pragma solidity ^0.8.0".

I tried multiple solutions provided in this thread (downgrading and changing solc version, and truffle compile --all), but none of them worked.

sjschweber · 2021-05-30T01:53:15Z

@haltman-at can you please re-open this issue

haltman-at · 2021-06-01T19:36:28Z

@sjschweber You're describing an different issue; this issue is about an undefined reference crash, not about being unable to compile due to pragma mismatch. If you are having an issue with pragma mismatch, you might want to file a new issue for that, but I'd suggest that rather than file an issue for that you might want to start with talking to our support team to make sure this is an actual bug. Thanks!
