Duplicate of #2104?

[kdy1]

@ljharb npm link was successful. Before getting this issue, my folder was removed when I canceled npm i -g @swc/cli

I get this issue even though @swc/cli installation was successful.

I can reproduce this.

Simplest reproduction I've whittled it down to so far:

#!/usr/bin/env bash
rm -rf prefix swc
mkdir -p prefix/lib
mkdir swc

# just a dummy file
cat >swc/package.json <<PJ
{
  "name": "@swc/core",
  "version": "1.2.23-alpha.1"
}
PJ

cat >swc/donotdelete <<DATA
please do not delete this file
DATA

args=(--quiet --audit=false --ignoreScripts --global)
arborist reify prefix/lib --add=file:swc "${args[@]}"

arborist reify prefix/lib "${args[@]}" --update # '--add=@swc/cli' also works

if ! [ -d swc/donotdelete ]; then
  echo 'DAMAGED'
  exit 1
else
  echo 'PASS'
fi

This seems related to a few different subtle issues combining. I can't seem to get it to reproduce in a simpler tree, so there's definitely something very interesting here relating (i think?) to a peer dep of both a top-level global package and one of its dependencies, which is not satisfied by the thing being linked, and where the peer dep itself has dependencies as well.

Ok, I have a fix for this. It'll be in the next npm release. Thanks @nlf for pairing through it with me.

This is fixed in npm 7.21.0
