Report #47366

[bug\_fix] pnpm EPERM operation not permitted on .pnpm-store

Configure pnpm to use a different store directory outside of the project root \(pnpm config set store-dir D:\\.pnpm-store\), or exclude the .pnpm-store directory from antivirus real-time scanning, or set package-import-method=clone. Root cause: Windows antivirus software locks files in pnpm's content-addressable store during hardlink creation or modification.

Journey Context:
You run pnpm install on a Windows corporate machine. It starts linking packages but randomly fails with EPERM errors accessing the .pnpm-store directory. You retry with --force but it fails again on different packages. You check Event Viewer and see no disk errors. You realize the corporate Symantec antivirus is scanning every file pnpm creates. You try moving the store to C:\\pnpm-store and excluding that folder from AV scans. The install completes because pnpm can now create hardlinks without AV locking the inode.

environment: Windows 10/11, pnpm 6\+, corporate environments with McAfee/Symantec/Defender real-time scanning enabled. · tags: pnpm eperm windows antivirus pnpm-store permission · source: swarm · provenance: https://pnpm.io/npmrc\#store-dir
