有个项目在mac下开发,安装包npm i,一切正常;
把这个项目放到linux机器上,安装包npm i,报了一堆warning:

仔细观察发现UNMET OPTIONAL DEPENDENCY的模块和npm ERR是同一批模块,也是安装时报warning的那些模块。
再仔细观察发现这些都是fsevents依赖的模块。
fsevents只能在macOS下安装,无法在linux系统安装。linux下会跳过fsevents模块,也不会安装fsevents依赖的模块。
这其实算是npm的一个bug,npm i时报Warn,npm ls又报Err,前后不一致,容易有误解。
目前无论用哪个版本的npm都会有这个问题,npm i --no-optional也不能解决这个问题。
这些报错不影响项目的正常运行,因为linux不需要fsevents。
如果不希望看到npm Err,可以用npm i -f强制安装,安装过程没有warn,安装完后npm ls看下:
└─┬ chokidar@2.1.5 └── fsevents@1.2.7
