我有节点11.2.0

继续收到这个错误。

Answer 1

您正面临文件权限问题。

-g参数npm的意思是“全局”，它将将这些文件安装在系统目录中，特别是在您的计算机/usr/local/lib/node_modules中，其中所有者可能是root，并具有rwxr-xr-x权限，这意味着那些不是root的人将没有写入的权限。

然后，您可以使用sudo获得该权限，或者像NPM modules won't install globally without sudo所说的那样，将npm前缀设置到您拥有权限的路径中：

$ npm config set prefix '~/.npm-packages'

Answer 2

你所需要做的就是在它之前用sudo运行相同的命令，

sudo npm install -g @vue/cli

系统会提示您输入管理密码。
