I have reset the metro but the same problem is happening. How can I solve this problem? The same problem is happening when I changed the port. I was facing the same problem when I rebuilt the project.

Delete the node_modules and package-lock.json. Install everything fresh and it should work.

Any idea what could possibly is wrong with package.json?
You have included #babel/plugin-proposal-decorators in your devDependencies.
By default, Heroku installs your dependencies and devDependencies, builds your slug, and then strips out your devDependencies. This makes sense: in most cases devDependencies shouldn't be on production; that's for things like testing frameworks, editor plugins, etc. that you need in development but not in production.
I recommend moving this module to your dependencies, though an alternative solution would be to tell Heroku not to prune your devDependencies by setting NPM_CONFIG_PRODUCTION=false or YARN_PRODUCTION=false, depending on the tool you're using.
Both approaches will require a redeploy to take effect, and unless you have a clear reason to use devDependencies on Heroku I urge you to use the former.

How can I fix this error?
and after a change to $ same error
I use npm install for angular 6 and for firebase functions, I didn't see any difference.
please help this is a bad error I don't know where is error specifically of version or other.
https://github.com/firebase/firebase-tools/issues/610
I solved this problem, It's very easy. You don't need to uninstall.
Step1: open firebase.json
you will show this JSON file
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint",
"npm --prefix \"$RESOURCE_DIR\" run build"
]
}
Step2: Delete "npm --prefix \"$RESOURCE_DIR\" run lint", and "npm --prefix \"$RESOURCE_DIR\" run build"
"functions": {
"predeploy": [
]
}
Step3: firebase deploy --only functions.
Step4: Like and share my solved.

I need to not allow tslint to fix found errors. For example, if it found comma missing, I need it to only tell me that it found it, and not actually fix it.
I found the "--no-fix" parameter in its vue-cli documentation, but it doesn't look like it is working. (I'm using npm run lint, where "lint": "vue-cli-service lint --no-fix" in package.json)
Are there any other ways to stop tslint's automatic fixes?
The "--no-fix" option works for me. Below is my configuration, please check your lint version:

I am testing my react/redux code with Mocha and expect, I got mocha configured to use es6 , but it seems to lack support for the array.prototype.includes even when I have a .babelrc specifying stage-0. And in my non-test code, array.prototype.includes works. Are there some settings aside from babelrc specific to mocha that need to be set in order to use array.prototype.includes?
