You probably need to run pnpm link --global. The -C option is not needed.

Alternatively, you may run in the directory of the B project:

pnpm link ../<relative path to A>

Thank you for your answer . but i tried to run as you said pnpm link --global in project A . Then run pnpm link --global @mom/utilsin project B.

A

 E:\git\mom-component\packages\com> pnpm link --global

C:\Users\QiYuei\AppData\Roaming\npm\pnpm-global\5:
- @mom/components
+ @mom/components 0.0.27 <- E:\git\mom-component\packages\com
 E:\git\mom-component\packages\com>

B

 WARN  Local dependency not found at C:\Users\QiYuei\AppData\Roaming\npm\pnpm-global\5\node_modules\@mom\components

C:\Users\QiYuei\AppData\Roaming\npm\pnpm-global\5:
- @mom/components 0.0.27

A package.json

 {
   "name":"@mom/components",
    "files": ["library" ],
    "dependencies": {
    "@mom/utils": "workspace:*",
    }
}

However, I found A strange phenomenon. For example, I changed the package name of A to '@lo/ d', which could be successfully linked by B

What are the reasons for this?

It was resolved after I deleted the folder C:\Users\QiYuei\AppData\Roaming\npm\pnpm-global

@zkochan this can be closed i readed it and the user sayed it is solved just wanted to ping you to clean up issues.

I find that I often need to delete this folder when I restart or re-pnpm link --global, but it always fails to link without deleting it. Is there something wrong with my operation? @zkochan

delete the folder C:\Users\QiYuei\AppData\Roaming\npm\pnpm-global

I have experienced this same confusing WARN  Local dependency not found at ... which results in the dependency being removed (at least indicated by the output). Deleting the pnpm-global and re-global linking the source-repo also worked for me until unlinking. #4638

Side note: I'm pretty sure I know by now how npm-link is supposed to work and that I have a healthy expectation of how pnpm-link is supposed to work - but I find the pnpm-link documentation page to still be quite confusing.
