Question

我正在尝试将Angular / CLI安装到我的Ubuntu系统上。

Ubuntu 18.04.4 LTS 64位

 node -v


npm -v

npm版本为 3.5.2

npm install -g @angular/cli

我已经安装了Node，它的显示版本为 v8.10.0 ，但是当我尝试安装Angular / cli时，它显示了一些错误，如下所示

 npm install -g @angular/cli

任何人都可以帮助我摆脱这个错误。

Answer 1

似乎您的NodeJS版本与Angular CLI版本不兼容。请参阅Angular CLI/Angular/NodeJS/Typescript兼容性详细信息here

我也建议使用NVM来管理NodeJS-这样，您可以轻松地在NodeJS版本之间进行切换。

Answer 2

您没有创建目录的写许可权，请尝试使用：

sudo npm install -g @angular/cli

Answer 3

尝试一下：

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

为我工作！

Answer 4

我有同样的问题：

解决方案很简单：依次运行以下命令。

sudo npm缓存清理-f
sudo npm install -g n
sudo n稳定

之后，运行以下命令来创建新项目。

ng新的

如果仍然有问题，则只需关闭终端，然后再次打开即可。

你很好！!!!
