Angular-cli需要root访问权限

Question

我使用命令npm install -g angular-cli安装了angular-cli。但是，每次我尝试运行任何ng命令时，它都会给我一个错误

Error: EACCES: permission denied, open '/home/m041/.config/configstore/ember-cli.json'
You don't have access to this file.

临时修复方法是更改文件权限。但是，每次我运行ng命令时，权限都会被重置！我的npm权限已修复。我可以在没有sudo的情况下安装包。但我正面临着cli的问题。任何帮助我们都将不胜感激。
