npm install報錯 npm ERR! enoent ENOENT: no such file or directory

在npm以後出現以下錯誤:vue

$ npm install
npm WARN checkPermissions Missing write access to /Users/lucas/code/js/vue/train/vue-sample/node_modules/follow-redirects
npm ERR! path /Users/lucas/code/js/vue/train/vue-sample/node_modules/follow-redirects
npm ERR! code ENOENT
npm ERR! errno -2

npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/lucas/.npm/_logs/2017-12-12T16_03_34_223Z-debug.log

關於這個錯誤,網上有不少解決方法,可是都不適用在我這裏。node

解決方法

從錯誤來看, 是 /Users/lucas/code/js/vue/train/vue-sample/node_modules/follow-redirects 這個文件沒有權限或者沒有找到。
而後 ls 了一下這個文件, 獲得以下結果:shell

$ ls -lt | grep follow-redirects
lrwxr-xr-x    1 lucas  staff     40 12 12 23:39 follow-redirects -> _follow-redirects@1.2.6@follow-redirects

能夠看到這個是一個軟鏈接,連接到 _follow-redirects@1.2.6@follow-redirects 這個上面,很明顯,在這個目錄是沒有follow-redirects 這個東西的。
怎麼辦呢? 很簡單 npm install follow-redirects 把這個東西安裝上去就行了。npm

安裝完成以後, 再 ls 一把this

$ ls -lt | grep follow
drwxr-xr-x   10 lucas  staff    320 12 13 00:22 _follow-redirects@1.2.6@follow-redirects
lrwxr-xr-x    1 lucas  staff     40 12 12 23:39 follow-redirects -> _follow-redirects@1.2.6@follow-redirects

能夠看到已經有了。debug

而後在 npm install 就沒有錯了。code
