Cannot find module `postcss`

[aleph-naught2tog]

The script we have been using for a long time with postcss-cli started failing on multiple, disparate branches this morning.

It fails the exact same way when we try to postcss-cli just to check its version. We see this behavior on 7.1.1; I see that postcss must be installed as a peer dep for version 8, but this error is on a version prior to that.

To reproduce:

1. Run npx postcss-cli --version

Output:

$ npx postcss-cli --version
npx: installed 87 in 6.138s
Cannot find module 'postcss'
Require stack:
- <home_dir>/.npm/_npx/21791/lib/node_modules/postcss-cli/index.js
- <home_dir>/.npm/_npx/21791/lib/node_modules/postcss-cli/bin/postcss

Current version: 7.1.1

We also tried it this on 8.0.0

npx postcss-cli --version is installing the latest version of postcss-cli from the registry, which is v8, which requires postcss as a peerDep. Try npx postcss --version in a project with v7 installed, and it should work fine.

after installing postcss as dep for postcss-cli the problem is fixed, thanks
