Npm install failed with “cannot run in wd”

  Linux环境下,root账户,安装某些npm包的时候报下面的错误,例如安装grunt-contrib-imagemin时:

Npm install failed with “cannot run in wd”

Error: EACCES, mkdir '/usr/local/lib/node_modules/coffee-script'
npm ERR! { [Error: EACCES, mkdir '/usr/local/lib/node_modules/coffee-script']
npm ERR! errno: ,
npm ERR! code: 'EACCES',

  解决办法如下:

  1. 执行npm install命令时加上--unsafe-perm选项:
    [sudo] npm install --unsafe-perm
  2. 或者将unsafe-perm选项添加到package.json文件中:
    "config": {
    "unsafe-perm":true
    }
  3. 不要使用preinstall脚本来安装全局模块,你可以单独安装它们然后在非root账户下安装其它模块,就像下面这样:
    sudo npm install -g coffee-script node-gyp
    npm install

  具体内容可以看下面这两个页面的介绍:

https://docs.npmjs.com/misc/scripts#user

https://docs.npmjs.com/getting-started/fixing-npm-permissions

  大致意思就是说:如果npm是在root账户下执行的话,它会将uid改成当前账户,或者uid的值从user配置文件中获取,而默认情况下uid的值为nobody。所以在root账户下运行npm install时需要将unsafe-perm选项加上。
