1. When running: npm run build:admin, an error occurred: NX Failed to process the project graph with “nx-js-graph-pllugin”. See Figure 1.

2. The reason is likely that the default package manager for this project is pnpm. See Figure 2.

3. Finally, I ran pnpm install and pnpm run build:admin in sequence. The execution succeeded, and the error no longer occurred. Generally, it is recommended to stick to a single package manager for a project and avoid switching back and forth, as this may cause issues.
