一整天，再怎么努力也没有成功安装...

For a whole day, no amount of effort has yielded a successful installation...

我禁用了防病毒软件并且多次重复安装，还重启我的机器，确保>VS Studio Code 关闭...，运行 npm cache clean，然后 npm cache clean --force，然后手动删除两个 npm 缓存 和 npm 文件夹位于 %APPDATA% 路径下，然后使用 npm install -g @angular/cli 重新安装 angular 所有相同的 EPERM 错误，...不同的文件，但相同的错误.

I have disabled the antivirus and severally repeated the install, also reboot my machine, ensured VS Studio Code is closed..., run npm cache clean, then npm cache clean --force, then manually deleted both npm cache and npm folders under the %APPDATA% path and then reinstalled angular with npm install -g @angular/cli all to the same EPERM error,... different files but same error.

我在某处阅读了降级到版本的建议.7，但我不能，因为我需要 angular ver.8...此外，ver.8 应该以某种方式成功安装！由于某个 React Native 项目，我还需要一个相当新的 Node.js.我到底应该怎么做?请帮忙.

I have read somewhere recommendations to downgrade to ver. 7, but I can't because I need angular ver. 8... Besides, ver. 8 should install successfully somehow! I also need a fairly recent Node.js because of a certain React Native project. What on earth should I do differently?? Pls help.

推荐答案

尝试使用以下方法卸载 CLI:

Try to uninstall the CLI using:

npm uninstall -g @angular/cli

并使用以下方法重新安装:

and reinstall using:

npm install -g @angular/cli
