Hello I am trying to do some coding and it seems something offed my package.json so bad even on a vscode restart it still won't find the preset-env its looking for.
here's what I've tried.
npm uninstall #babel/core #babel/preset-env #babel/preset-react
npm install #babel/core #babel/preset-env #babel/preset-react
blowing away the entire project and starting fresh and to no avail none of it has worked.
looking at my package.json
{
"name": "peek-me",
"private": true,
"version": "1.0.0",
"description": "",
"main": "package.json",

}
}
I'm really stumped as to why this is all of a sudden an issue

I've got this error from the heroku console when deploying the app.
It work on local but fail to deploy.
SyntaxError: /tmp/build_4b397c70/.heroku/node/lib/node_modules/npm/docs/gatsby-browser.js: Support for the experimental syntax 'jsx' isn't currently enabled (7:10):

Add #babel/preset-react (https://git.io/JfeDR) to the 'presets' section of your Babel config to enable transformation.
If you want to leave it as-is, add #babel/plugin-syntax-jsx (https://git.io/vb4yA) to the 'plugins' section to enable parsing.

I added #babel/preset-react to the 'presets' section of the babel config and still got the same error
NOTE: it's a simple nodejs server api not a react one, but the error suggest the use of preset-react.
I've had same problems with Heroku when generate build directory. You change directory input to other (for example src).
I share you my builder and start script:
"prebuild": "rm -rf ./dist",
"build": "babel ./src -d ./dist --ignore node_modules,test",
"prestart": "npm run build",
"start": "pm2-runtime start ./dist/index.js"
I have created my own npm package but while using in a test application am getting the following error: Add #babel/plugin-transform-react-jsx to the 'plugins' section of your Babel config to enable transformation.
Note: I've written my component in JSX

Thanks in advance.
You need to add that to your .babelrc file, not package.json
I have the problem that Heroku searches in the folder app/build/index.js for my index.js but this is wrong. That is why I get this error: 1
My folder structure looks like this: 2
My package.json:

My Procfile:

How can I solve this problem?
I am getting a
"regeneratorRuntime is not defined"
when trying to use async/await in a project.
My babelrc file is this currently:
{
"presets": ["env", "react"],
"plugins": [
"transform-runtime",
"transform-object-rest-spread"
]
}
and my package.json is:
{

}
}
I'm sort of new to configuring babel so not sure what to do here.
I fixed a similar problem using the following post
Try the following in .babelrc:
{
"presets": ["#babel/preset-env"],
"plugins": [
"#babel/plugin-transform-runtime"
],
...
with the following dev dependencies:
#babel/plugin-transform-runtime #babel/runtime
I think it is because you are using #babel/runtime.
My set up is #babel/runtime, #babel/core, #babel/plugin-transform-runtime and in the .bablerc set
"plugins": ["#babel/transform-runtime"]
I hope this helps.
I was getting error installing expressJs to my packages. I have had to do an npm cache clean --force no sucess, then I deleted my node_modules and package-lock.json, I try to reinstall packages using npm i I still got an error.
Now I deleted node.js from my pc windows 10 and downloaded and installed the latest node and tried to reinstall the project packages again. Now the error I get is this
$ npm i

I had to delete all of npm-cache directly from my windows 10 pc, from %AppData%, ie ~/AppData\Roaming\npm-cache. Everything works fine now.
