pnpm i --frozen-lockfile hangs in CI on 7.20+7.21

[THOUSAND-SKY]

pnpm version:

7.20.0 or 7.21.0

Code to reproduce the issue:

This bug happens to me on gitlab CI. This is probably close to the issue, although the error message is not the same (in fact, in the actual pipeline I see no error at all, it just hangs and then gets killed).

There 7.19 works but 7.20/21 are failing.

Expected behavior:

pnpm i --frozen-lockfile should complete in CI, like it did on 7.19.

Actual behavior:

Install hangs mysteriously. Or in the reproduce case, produces ERR_PNPM_PREPARE_PKG_FAILURE .

Additional information:

• node -v prints: 16.16.0 (in the container)
• Windows, macOS, or Linux?: linux (+ docker)

Oh this new error is actually leading me to the duplicate bug, now that I have that to search for 😝
