我正在尝试安装角度cli。我安装了npm版本5.6.0和节点v8.11.1。这是我在命令提示符（admin）中所做的：
justine:~ justine$ sudo npm install -g @angular/cli

让你知道我尝试了什么：
npm cache verify不知道下一步该尝试什么。你能帮忙吗？
使用npm cache clean清理缓存，卸载angular-cli npm uninstall -g angular-cli并使用npm install -g @angular/cli重新安装或者尝试使用npm install -g -f angular-cli强制安装。
如果将节点和npm版本升级到最新版本会更好。之后请按照以下步骤安装angular / cli：
希望上面的技巧解决你的问题。
我有同样的问题。我用这个解决了：sudo npm install -g --unsafe-perm angular-cli
