Cannot remove unused optional dependency

[ThisIsManta]

my original package.json was...

"devDependencies": {
  "vite": "^5.4.8",
  "stylus": "^0.63.0",
}

running pnpm why stylus gave me...

stylus 0.63.0
vite 5.4.8
└── stylus 0.63.0 peer

the lock file looks like... (click to expand)

later on, I want to remove stylus in favor of something else (doesn't matter) so I run pnpm remove stylus

running pnpm why stylus over again gave me...

vite 5.4.8
└── stylus 0.63.0 peer

but the lock file is almost unchanged. more importantly, it still has the "snapshot" of

  [email protected](@types/[email protected])([email protected])([email protected])([email protected]):
    dependencies:
      esbuild: 0.21.5
      postcss: 8.4.45
      rollup: 4.21.3
    optionalDependencies:
      '@types/node': 20.16.1
      fsevents: 2.3.3
      sass: 1.77.7
      stylus: 0.63.0 <--- I don't need it anymore!
      terser: 5.32.0

the question is, how do I remove stylus completely as it is clearly listed as an optional dep?
of course, I can delete and regenerate the lock file (pnpm-lock.yaml) but that might break other deps.

Never mind. I have removed every mention of stylus in the lock file manually together with rm -rf node_modules and rm -rf $(pnpm store path)

From pnpm v9.12 you can use this override to remove stylus from any dependencies:

{
  "pnpm": {
    "overrides": {
      "stylus": "-"
    }
  }
}
