无法在 Ubuntu 16.04 中安装 Angular CLI

Question

我无法在 Ubuntu 16.04 中安装 Angular CLI。进入后sudo npm install-g angular-cli，加载和写入需要很长时间。

您需要从“/usr/local/bin”中手动删除“ng”文件夹。

因此运行以下命令：

sudo rm -rf /usr/local/bin/ng

然后再次安装 Angular Cli：

sudo npm install -g @angular/cli

如果第二个命令仍然不起作用，请尝试强制安装添加-f：

sudo npm install -g -f @angular/cli

面临同样问题的其他用户可能必须删除/usr/bin/ng而不是/usr/local/bin/ng.
