我做了npm安装，但仍然没有成功，根据你来自哪里？

由于

Answer 1

您需要重新安装@angular/cli。请按照以下步骤操作：

npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm install --save-dev @angular/cli@latest
npm install

Answer 2

sudo npm cache clean --force
sudo npm install -g @angular/cli@latest

它对我有用

我尝试使用npm install npm @ latest -g它现在完美无缺，谢谢大家：）
