`node_modules` is present warning with pnpm

Question

When I run pnpm install in my project I get a warning:

`node_modules` is present. Lockfile only installation will make it out-of-date

What will be out of date. node_modules the lockfile? Should I be concerned about this? How can I fix this?

I am using pnpm version 9.11 with pnpm workspaces.

Answer 1

What Will Be Out of Date?

• node_modules: May not match the state described in pnpm-lock.yaml.
• pnpm-lock.yaml: May not reflect changes in node_modules.

Should I Be concerned about this?

Yes, if you need consistency between node_modules and pnpm-lock.yaml, especially in workspaces or deployments.

How can I Fix This?

1. Proper Installation: Run:

   pnpm i
   

2. Clear and Reinstall:

   rm -rf node_modules
   pnpm i
   

3. Validate Lockfile:

   rm -rf node_modules pnpm-lock.yaml
   pnpm i
   

4. Check Workspace Configs: Ensure pnpm-workspace.yaml and lockfile are up to date, then run:

   pnpm i
