After careful observation, it is found that UNMET, OPTIONAL, DEPENDENCY and npm, ERR are the same batch of modules, which are also the modules that are installed in warning.
A closer look reveals that these are the modules fsevents relies on.
fsevents can only be installed under macOS, not on linux systems. fsevents modules are skipped under linux and modules that are fsevents dependent are not installed.
This is actually a npm 1 bug, npm i times Warn, npm ls Err, again not before and after 1, easy to have a misunderstanding.
No matter which version of npm is used, npm i --no-optional cannot solve this problem.
These errors do not affect the normal operation of the project because linux does not require fsevents.
If you do not want to see npm Err, you can use npm i -f mandatory installation, installation process does not have warn, after the installation of npm ls see:
└ ─ ┬ chokidar@2.1.5
└ ─ ─ fsevents@1.2.7
It's clean. There's no error.
My project is chokidar. This module relies on fsevents, and chokidar relies on browser-sync, webpack, etc.
