angular 安装运行没有权限的问题

问题症状

g new my-project
/usr/local/lib/node_modules/angular-cli/node_modules/configstore/index.js:54
                throw err;
                ^

Error: EACCES: permission denied, open '/Users/xuys/.config/configstore/ember-cli.json'
You don't have access to this file.

    at Error (native)
    at Object.fs.openSync (fs.js:549:18)
    at Object.fs.readFileSync (fs.js:397:15)

解决方法：

修改ng目录的权限为当前用户的权限。

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
