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。
