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：

执行npm ls，有不少UNMET OPTIONAL DEPENDENCY的模块，最后还报了一堆错：

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

干净了，没有任何报错。

我的项目是chokidar这个模块依赖了fsevents，chokidar又是browser-sync、webpack等依赖的。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
