安装Yo时权限被拒绝

Question

我正在尝试设置你以使用角度生成器进行项目.我按照这里详细说明的步骤进行操作:http://yeoman.io/learning/index.html

我已经安装了Node.js和NPM.

但是当我使用命令时:

sudo npm install -g yo bower grunt-cli

它失败了,我收到了这个错误:

> spawn-sync@1.0.11 postinstall /usr/lib/node_modules/yo/node_modules/cross-spawn/node_modules/spawn-sync
> node postinstall


fs.js:439
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);

我尝试使用chmod 777 on /usr/lib/node_modules但似乎没有更好的效果.

我可以安装Bower和Grunt,它有效,但是当我尝试安装Yo时,它每次都失败了......

我不知道该怎么办,因为我尝试过chmod或者chown没有用过.

谢谢你的帮助!:)

Answer 1

我使用以下方法解决了这个问题:

sudo npm install -g yo --unsafe-perm

--unsafe-perm在此错误报告中使用nyakto建议的.

编辑 - 意识到这是@Stephan在他的回答中发布的URL.

我不知道有关--unsafe-perm的具体信息 - 我只能说它允许我安装你没有错误,我经历过与OP非常相似/相同的错误.

Answer 2

github repo中的评论解决了我的问题.基本上只需要更新节点版本.列出以后参考的步骤:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable
node -v
