node.js - 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sudo npm install -g angular-cli后，加载写入时间较长。

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。
