Angular 安装问题和权限在 Mac 上失败，为什么？

Question

这是第一次使用 Angular。我检查我有所需的节点版本，但我会收到权限错误，我不确定为什么？我正在使用 Mac，但出现权限失败或拒绝错误。我还尝试了 sudo npm install -g @angular/cli。有什么猜测吗？因为我不知道该怎么办。

您的~/.npm-global 目录中似乎存在权限问题。

如果存在 .npm-global 文件夹，请首先检查您的主目录。

如果有，请尝试这些命令。

sudo chown -R $(whoami) ~/.npm
sudo chown -R $(whoami) ~/.npm-global

然后尝试再次安装 Angular。

如果你没有.npm-global文件夹，我建议你用节点版本管理器重新安装npm。
