  • 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:

    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: 3,
    npm ERR!   code: 'EACCES',
    npm ERR!   path: '/usr/local/lib/node_modules/coffee-script',
    npm ERR!   fstream_type: 'Directory',
    npm ERR!   fstream_path: '/usr/local/lib/node_modules/coffee-script',
    npm ERR!   fstream_class: 'DirWriter',
    npm ERR!   fstream_stack: 
    npm ERR!    [ 'DirWriter._create                 (/usr/local/lib/node_modules/npm/node_modules/fstream/lib/dir-writer.js:36:23)',
    npm ERR!      '/usr/local/lib/node_modules/npm/node_modules/mkdirp/index.js:37:53',
    npm ERR!      'Object.oncomplete (fs.js:297:15)' ] }
    npm ERR! 
    npm ERR! Please try running this command again as root/Administrator.

      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。
