I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

[merlinnot]

Could you try to update TypeScript first?

[thechenky]

Hi @agordeev thanks for filing - can you try @merlinnot 's suggestion and change your package.json typescript declataion to this:"typescript": "^3.1.3?

[zbarbuto]

Can confirm bumping typescript to 3.1.3 fixed for me (was on 2.8.3)

[agordeev]

npm install typescript --save-dev did the trick. Thanks!

[thechenky]

Awesome, thanks everyone! Glad your issue was resolved @agordeev :)

[nikhilbhalwankar]

I upgraded typescript to 3.3.1 which solved this issue.

[thechenky]

Seeing as caused issues for a few people, we have now added the mention of TypeScript update into the release notes for v2.2.0. Thanks again everyone :)

[GIOkafor]

@RUPALAVECINO did you try updating to firebase-admin@^7.0.0?

I ran npm install typescript --save-dev but still got errors which running: npm install firebase-admin@^7.0.0 made go away.

It could be that package(firebase-admin), or another peer dependency preventing it from installing.

[danieldanielecki]

When working on webpack changing "typescript": "~3.2.2" on "typescript": "^3.3.1" and hitting 'npm install' afterwards made the job.

[manel00]

Sorry but there's no clear answer for me, can anyone put something to clearify it please?

[merlinnot]

Sure. This library uses syntax introduced in TypeScript 3.4, which allows us to provide better experience to our users by having better autocompletion and stricter compiler (static) checks, so your code breaks less in runtime.

The specific syntax that causes the issue for you is const assertion (as const), introduced in TypeScript 3.4: microsoft/TypeScript#29435

You need to update your TypeScript compiler to at least this version, by running e.g. npm i --save-dev typescript@latest.

As a side note, I can recommend automatic your dependency update process by using tools like [Renovate](npm i --save-dev typescript@latest), which take this burden off your shoulders.

[manel00]

Sorry but it doesnt work still, i did it before

[merlinnot]

Please provide a minimal repro so I can reproduce it and help. Otherwise it's impossible.

[manel00]

Sorry i tried everything but doesnt work.... cannot put typescript last version, its incompatible with angular compiler

[manel00]

Please need help to fix it, its very annoying....

[merlinnot]

Angular requires TypeScript compiler from range 3.4, so that should be perfectly fine:

If you use tsc from a command line, it uses your global installation. Try running it through npx: https://blog.npmjs.org/post/162869356040/introducing-npx-an-npm-package-runner.

[kkusanagi]

i use back old version thats work.
here.

"dependencies": {
  "express": "^4.17.1",
  "firebase-admin": "^7.4.0",
  "firebase-functions": "^2.3.1",
  "firebase-tools": "^7.2.4"
},
"devDependencies": {
  "tslint": "~5.8.0",
  "typescript": "^3.5.3"
},

[Spiralis]

@merlinnot I have made sure to upgrade the global tsc too, and also made sure that I was using the global one. Not working. I forced using the local tsc too. None of the approaches worked.

@kkusanagi I will try those versions asap, thanks:

[drsamdonegan]

@Spiralis I've found a combination of the most updated versions that appears to work for me:

"dependencies": {
"firebase-admin": "^8.5.0",
"firebase-functions": "^3.0.2"
},
"devDependencies": {
"tslint": "~5.8.0",
"typescript": "^3.3.1"
},

[drsamdonegan]

@Spiralis These are the most updated versions that appear to work:

"dependencies": {
"firebase-admin": "^8.5.0",
"firebase-functions": "^3.0.2"
},
"devDependencies": {
"tslint": "~5.8.0",
"typescript": "^3.3.1"
},

[Spiralis]

I tried to produce a minimal case to reproduce and it all worked. However, as I moved the functions folder into the same project as my netxjs/react/firestore typescript application (using yarn), the compilation failed.
At the moment I am instead keeping the firebase functions in a separate project. It might be mix of npm and yarn, it might be something different. I don't have the time to investigate more, as I have to do some actual coding too :)

[merlinnot]

If anyone is able to provide a reproduction, I'll gladly fix it. But it seems to me that it's just a matter of TypeScript version.

[Spiralis]

Well. I am not sure anymore. I have had different errors. But, it seems to me that I am not able to set this up as a sub-folder in my main firebase repo. That is, where I host my typescript nextjs firebase project, using yarn. I can set it up as a separate folder and repo it seems, but within that repo, no go. So, I have made a separate repo for it now.

[carlosefonseca]

I think I have the latest ts, tslint, firebase-admin,firebase-functions and it doesn't work…

Sorry, just found this aws/aws-cdk#3839, fixed with npm install @types/node@8.

Installing the latest version of typescript globally npm install -g typescript worked for me.
Also I updated the typescript version in functions/package.json.

[carlbonsu]

This worked for me:

1. npm install -g typescript (has to be installed globally so yes -g is needed)
2. Restart Visual Studio (in my case I was using vscode)

Similarly to @ms-prasanth I'm on "typescript": "^3.9.7" and it works. Simply try to install this version of TypeScript, I can see that you're on TypeScript 4 already.

[sebasas15]

I had the same problem but with @google-cloud/pubsub and just upgrading to "typescript": "^3.9.7" was the solution for me.

[Kgaugelo-Molema]

npm install typescript --save-dev did the trick. Thanks!

Thank you for the solution :-)

solved for me

suddenly at 16.4.5...

"typescript": "4.2.4"

[Khufos]

Apaguei a pasta node_modules depois apaguei pasta onde estava os arquivos com esse error e depois instalei npm install typescript --save-dev , depois refiz os arquivos ai voltou ao normal , também é bom da um reload no vscode .
