我一次又一次地尝试......但它不起作用。请帮帮我！！

【解决方案1】：

我们在这里遗漏了一些信息；你说你得到一个安装错误，但这些只是关于不推荐使用的依赖项的警告。此外，这些依赖项看起来与@vue/cli 本身并没有太大关系……

这些是全局安装的依赖项吗？您可能想使用 npm-check 并在全局范围内使用它来查看这些是否是您应该更新（或摆脱）旧的全局依赖项：

$ npm-check -ug

【讨论】：

我尝试 npm-check -ug.. 但它不起作用。所以我安装了npm install -g npm-check，但打开了错误消息npm WARN deprecated cross-spawn-async@2.2.5: cross-spawn no longer requires a build toolchain, use it instead npm WARN deprecated core-js@2.6.12: core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.
这也不是错误，仍然是警告。 npm-check 现在应该已经安装好了，所以再次尝试该命令，看看它是否有任何作用？
我会做npm-check -ug，但会打印错误消息zsh: command not found: npm-check
好吧，我不能在这里说太多......如果你输入@vue/cli --version，会出现什么吗？
错误看起来像这样.. zsh: no such file or directory: @vue/cli

【解决方案2】：

我已经用这个方法解决了：

npm 卸载 –g @ionic/cli
安装nodejs
再次重新安装：npm install –g @ionic/cli

【解决方案3】：

对于 Mac 用户

首先，卸载 angular/cli：sudo npm uninstall -g @angular/cli

然后，转到 https://www.brew.sh/ 并复制 Install Homebrew 下面的链接并将其粘贴到终端并按 Enter。

然后，输入：brew install angular-cli 并回车。

最后查看版本：ng --version
