Description

@bcg

Was following the Tachyons And React Tutorial and ran into this error:

$ tachyons src/css/app.css > src/index.css --minify

/usr/local/lib/node_modules/tachyons-cli/node_modules/caniuse-api/node_modules/browserslist/index.js:37
    throw new BrowserslistError(name);

    $ create-react-app --version
    2.0.3
    

    from which package.json, isn't that list necessary in order to autoprefix stuff

    It is the package.json that create-react-app creates for new applications. I didn't mean to indicate it was resolved, I was just adding some additional notes.

    I think it is because a downstream dependency is using a really old version of browserslist.

    Any news on this, seems that without this list the compiled css will not work on some browsers.

    My temporary fix in my case was to create an empty .browserslistrc at the root of tachyons

    If no one got a solution for this issue, yet, I think there is a one!
    update the browserslist version to be > 3.0 in each of these dependencies:

    • tachyons-cli/node_modules/caniuse-api/
    • tachyons-cli/node_modules/postcss-merge-rules/
    • tachyons-cli/node_modules/postcss-merge-rules/node_modules/caniuse-api/

    Can you explain how should I do this?

    this is an explicit solution for the problem that you need to change browserslist version through your local node_modules in the previously mentioned packages and hence, this should not be applicable for your app release it should be fixed in the next versions of tachyons-cli itself!

    there is another solution for this if tachyons-cli don't fix this in a next version. you can fork their repo, apply the fix by yourself (say in a new branch) and install it by github not from npmjs.com
    as following in this link

    Looks like the issue originates from cssnano package which is used by tachyons-build-css
    browserslist/browserslist#266 (comment)

    I think that tachyons-build-css need to upgrade cssnano to the version 4. For that moment it uses "cssnano": "^3.10.0",

    I've opened an issue in the tachyons-build-css repository, upvote it please if you think that it is relevant.

    my solution was updating "cssnano": "4.1.10", and "autoprefixer": "9.6.1",
