状況

警告やエラーの内容をみると、権限がたりないっぽい。

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules/e2d3/node_modules/basic-auth
npm ERR! Error: EACCES: permission denied, access '/usr/local/lib/node_modules/e2d3/node_modules/basic-auth'

回避策

sudoつけて再実行したらいけた

  • ×　 $ npm install -g e2d3
  • ○　 $ sudo npm install -g e2d3

sudoなし(失敗)

実行例

$ npm install -g e2d3
