Failing to install on Raspberry Pi Zero 2 W

[gunnarsson]

I'm having a hard time installing i2c-bus on my Raspberry Pi Zero 2 W. I'm running Node 20.4.0 and npm 9.8.1. The docs clearly state that Node versions 10, 12, 14, 15 and 16 are supported, but I can install the module locally on my Mac with Node 20 without any issues. Is there anything I can do to work around this problem myself?

Here's what I believe is the relevant part of the npm log:

Any help would be much appreciated!

I don't have a Raspberry Pi Zero 2 W and I'm afraid I can't reproduce the error on a Raspberry Pi 4.

If I run the following commands on a Raspberry Pi 4:

node -v
npm -v
uname -a
npm install i2c-bus
npm list --all
node node_modules/i2c-bus/example/i2cdetect
node node_modules/i2c-bus/example/i2cfuncs.js 

Everything functions as expected and this is what is see:

Are you perhaps installing an old version of i2c-bus?
Exactly what command(s) are you using to install i2c-bus?
If you run the commands shown above, exactly as shown, from an empty newly created directory, what is the complete output?

[gunnarsson]

Thanks for looking into this so quickly! I tried what you suggested (plus an npm init in the directory) and everything works perfectly. The directory where it doesn't is an existing Node project, so I assume one of the other modules has incompatible dependencies.

After a quick look through the package tree, I think the culprit might be:

├─┬ pigpio@3.3.1
│ ├─┬ bindings@1.5.0
│ │ └── file-uri-to-path@1.0.0
│ └── nan@2.15.0

... as my test directory has nan@2.17.0. I'll fiddle around a little with it, thanks for your time!

[gunnarsson]

For anybody else running into this issue, manually installing the correct version of nan and then re-running the i2c-bus installation seems to have done the trick. I haven't had time to verify the installation yet, but at least it went through without any error messages.

[fivdi]

@gunnarsson Thank you for this additional information and for opening the issue initially. I'll reopen the issue as there is a problem with the i2c-bus dependencies. As can be seen here i2c-bus@5.2.2 depends on nan version "^2.14.2". This dependency needs to be updated to "^2.17.0".

[gunnarsson]

All right, that explains why it failed in the first place given these circumstances. Thanks again for looking into this!

[fivdi]

All right, that explains why it failed in the first place given these circumstances. Thanks again for looking into this!

Yes, that explains it.

[fivdi]

The problem should be resolved with i2c-bus@5.2.3 which has just been published on npm.

@gunnarsson Once again, thank you for reporting this issue.

[gunnarsson]

Fantastic! I re-started with the new version, and I can confirm that the installation went smoothly.
