Firebase deploy returns error at tsc command

Question

I've setup a Firebase project to create some basic Firebase Functions.
In the project I'm using TypeScript

Following the Firebase official documentation I created my project.

The last step, firebase deploy --only functions, gave an error with the tsc command.

$ firebase deploy --only functions

=== Deploying to ‘my-project’…

i  deploying functions
Running command: npm --prefix "$RESOURCE_DIR" run lint

> functions@ lint /path/to/functions
> tslint --project tsconfig.json

Error: functions predeploy error: Command terminated with non-zero exit code2

Having trouble? Try firebase deploy --help

It seems that some of the Firebase library code does not pass the tsc compile/transpile step. I'm looking for a way to make this deploy step pass.

I've followed the suggestion given at this GitHub issue, which included:

Adding --skipLibCheck to the tsc command
Adding skipLibCheck to the project's generated functions/tsconfig.json
Adding isolateModules to functions/tsconfig.json
Adding ./functions/node_modules/@types to the typeRoots array in the functions/tsconfig.json file.
Adding dom to compilerOptions.lib in functions/tsconfig.json

None of the above steps have worked for me.

How can I make my deployment to Firebase succeed?

Hey Rick, what did you do to solve this issue? Changing the versions as below didn't work well. Did you manage to solve this ? THANKS!! — On the way to success

A year and a half ago, that did the trick. See the accepted answer, upgrade to the latest typescript version, clear cache and retry, these are the things I would do. — Rick Slinkman

Ran into same issue, was able to deploy after upgrading typescript library to 3.3.1 version and do npm install.

In package.json file set "devDependencies": { "tslint": "~5.8.0", "typescript": "~3.3.1" },

Note: you can remove all changes described in your post.

Thank you, I was using typescript: 2.8.4 and updating to ~3.1.1 did the job.

This answer didn't fix the problem for me. But there were several successful solutions in the GitHub issue the OP mentions. I found the one about adding type roots to the tsconfig.json to be the best: git.io/JeZrh

In my experience TS, FB, Angular, Ionic move so quickly that 7month old issue and answer is very outdated.

this works for me : add this line to tsconfig within the functions folder:

"typeRoots": [ "node_modules/@types" ],

This is part of "compilerOptions" block worked for me
