Parcel: Thrown error: Couldn't find preset "env" relative to directory

[StanleySathler]

Hello guys!
First of all: thank you for this awesome job. It looks amazing!

I tried run the parcel index.html command for the first time and the following error was thrown:

/Users/stanley/.config/yarn/global/node_modules/parcel-bundler/src/builtins/css-loader.js: Couldn't find preset "env" relative to directory "/Users/stanley/.config/yarn/global/node_modules/parcel-bundler/src"

To solve that, I had to install babel-preset-env package (also globally).

NodeJS: v9.0.0 (stable)
OS: Mac OS X Sierra 10.12.6

you can also enter both just in the project.
I have it available at https://github.com/davidsonsns/parcel-react-app.

but anyway I also believe that there should not be this error.

I have the same problem but using npm
NodeJS: node v8.8.1
OS: Mac OS X Sierra 10.13.1

hey @devongovett, I think this is happening because babel-preset-envshould be a dependency, not a devDependecy

[albizures]

this is related to #6

[devongovett]

Ah I see. It's because the .babelrc in parcel is being published to npm, so parcel is trying to compile its own code for the small JS runtime that is included alongside CSS to do hot reloading. Then babel tries to find preset-env which is specified in there, even though we don't really need it.

Added .babelrc to .npmignore in 30616e94ee852560ba4ba52fc2faa605136d4154.

[devongovett]

Should be fixed in v1.0.2.

[rwieruch]

Good job @devongovett 🎉 Looking forward to it. Just a great way how you solved the whole thing :)

[evenfrost]

Weird thing, happens for me as well for no apparent reason. I've managed to fix it with npm i babel-preset-env && npm uninstall babel-preset-env (!).
