无法正确安装@angular/cli

Question

npm install 崩溃了：

sudo npm install -g @angular/cli

我尝试用 cash clean 卸载它几次，然后用 @angular/cli 重新安装它，它总是崩溃。

Answer 1

彻底删除你的 node_modules 目录，然后再次运行 sudo npm install

如果需要的话你可以试试这个：

要在本地安装 @angular/cli，请运行 npm install @angular/cli --save，而要在全局安装它，请运行 npm install -g @angular/cli。

但如果它需要 root 访问权限，那么您必须包含 sudo，这将是 sudo npm install -g @angular/cli。

或视情况检查您的网络连接（互联网）。

希望对你有帮助
