[Bug] Missing resolver

[JesusTheHun]

• I'd be willing to implement a fix

Describe the bug

While trying to install the very popular tailwindcss, I run into this error :

$ yarn add -D tailwindcss@npm:@tailwindcss/postcss7-compat @tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9
➤ YN0001: │ Error: tailwindcss@npm:@tailwindcss/postcss7-compat isn't supported by any available resolver
...

To Reproduce

The commend above will trigger the error. I tried to run this into Sherlock but it seems broken itself :/

Environment if relevant (please complete the following information):

• OS: OSX 11.2.1
• Node version: 15.8.0
• Yarn version: 2.4.0

tailwindcss@npm:@tailwindcss/postcss7-compat

You're lacking a version, try

yarn add -D "tailwindcss@npm:@tailwindcss/postcss7-compat@*" @tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9

Don't you think you should support that format as a compatibility feature ? Since the package manager next door support this syntax.

Edit : one should also note that the issue has been reported to tailwindcss and their response is pretty clear :

This sounds like a Yarn 2 or system related issue to me unfortunately, as this works as expected with npm. Going to close as no plans to dig in to this ourselves and this is the first time it has been reported. If it's a widespread issue we can circle back, or hopefully someone who actually uses Yarn 2 and has run into it and fixed it can share their solution.

Sure, the issue this is a duplicate of is still open for that reason
