Hi @r65068! I'm Dosu and I’m helping the dify team.

The error happens because your environment (often a container or restricted filesystem) blocks Python from creating symlinks during virtual environment setup, which is required by Python 3.12. This is a common issue in Docker or when volumes are migrated with zip (which loses symlinks) instead of tar.

You have a few options:

• If you can, adjust your container or filesystem settings to allow symlinks. For Docker, make sure you use tar for volume migration to preserve symlinks, not zip [details].
• The most reliable workaround is to use the dify-plugin-repackaging tool on an online machine. This tool downloads and bundles all plugin dependencies into an offline package, so Dify won’t need to create a new virtual environment with symlinks during install. Then, upload the offline package via "install from local file" in the Dify plugin page [instructions].
• If you use the offline install method, set FORCE_VERIFYING_SIGNATURE=false in your .env file and restart your Dify containers to avoid signature errors.
• As a last resort, you can manually enter the plugin daemon container, recreate the virtual environment, and install dependencies, making sure symlinks are preserved [steps].

If you need more targeted help, sharing your OS, container runtime, and filesystem details can help pinpoint the restriction.

To reply, just mention @dosu.
