Hello @schalkneethling

hope that everything going fine with

glad to see some official review here after @chrisdavidmills so we can learn more

some user report some issue related to the tools and testing section

Tools and testing - Learn web development | MDN

here are one of them

Help needed with Introducing a complete toolchain

I think I finally found the fix. tldr: Follow the instructions as provided but before running the transformation with npx parcel src/index.html, add "postcss-preset-env": "^6.7.0", to package.json. Long version I repeated the steps in the instructions of Introducing a complete a toolchain too many times to count. I worried I must be making an error in copying somewhere but even copy/pasting commands and file content repeated the same errors. I posted here and to Stackoverflow seeking guidance…

the issue related that it use old version of the tools which make conflict if user used new version like when installing dependency without specify the version which install the latest version by default and the issue start from that point

so if you have time could you or someone else reviews this section and check if all example working with the new version or at least change the installation to specify the version to be installed

thanks for your time and have a nice day

For this particular case there’s an issue at mdn/content:

Issue with "Introducing a complete toolchain": fails to build; problem with postcss-preset-env versions

In general, there are several similar issues about outdated code when looking at the “Content:Learn:Client-side” label on GitHub:
