parcel: Unknown version 62 of android

I have the exact same error message with only env in babelrc’s preset, and removing node_modules and .cache or .babelrc doesn’t help.

Apparently we are using a newer version of browserslist than babel-preset-env. Parcel computes what browsers to support, then passes it off to babel. But since babel is using an old version of browserslist that doesn’t know about new browsers, it fails. I opened a PR to fix it: https://github.com/babel/babel-preset-env/pull/458

I’m also experiencing this issue after upgrading to 1.7.0. Tried the steps mentioned here, to no avail.

Yupp… Yarn was the problem. After doing npm install -g parcel-bundler, it began working properly.

Try using npm instead of yarn 😕

Just tried yarn installing and running parcel-bundler for the first time on a create-react-app Typescript project, ran into this:

.../src/main.tsx: Unknown version 63 of opera

I have no .babelrc. We have to use yarn for our project.

How is this any better than webpack, I wonder, with errors like this?

Ok, it was my fault 😃 yarn install only installs the exact version of the packages, as the babel-preset-env version in parcel is ^1.6.1, I had to execute yarn upgrade

Thanks for the help @DeMoorJasper you helped me figure it out

@yashspr comment solves this. Maybe opening an issue to yarn to debug this?

just faced issue like this

I just tried to use Parcel like in Getting Started and got this:

^C

fixed with installing Parcel in package.json, and it’s fixed

@aceofspades Not reproducible any more. No errors. so war. For simple use case parcel is ok. But in my opinion parcel is not production ready. 👯

For anyone else having this issue - you’re not alone. There doesn’t seem to be a single issue causing it.

I’m still facing this issue. All I’m doing is <script src="./node_modules/bootstrap/dist/js/bootstrap.min.js"></script> in my index.html. I don’t have any config either.

@JonathanHuot I don’t mind reopening this issue, but I think it’ll be better to open a new issue describing what you would like to see improved and how you’d want the error to look and referencing to this issue. Besides having a better overview of the issues that way it would also get more attention than reopening an old solved issue

I meet the same problem… with my package browsers list:

"browserslist": [
    "> 1%",
    "last 2 versions",
    "not ie <= 10"
  ]

and remove node_modules didn’t work, also I removed the browser’s list in .babelrc of preset env, didn’t work too…

wired question.
