在项目期间，我想模仿 ( ionic cordova emulate ios)，然后它问我（我通常说是）：

? The Ionic CLI (local version) has an update available (3.20.0 => 4.0.1)! Would you like to install it? Yes
> npm i -D -E ionic@latest
✔ Running command - done!

[OK] Updated Ionic CLI to 4.0.1! 

Please re-run your command.

Note: You can downgrade to your old version by running: npm i --save -E ionic@3.20.0

之后我尝试重新运行该命令，但它就像它不再识别该命令ionic cordova emulate ios：

[ERROR] Unable to find command: /usr/local/bin/node /Users/$ME/.npm-packages/bin/ionic cordova emulate ios

   _             _
  (_) ___  _ __ (_) ___
  | |/ _ \| '_ \| |/ __|
  | | (_) | | | | | (__
  |_|\___/|_| |_|_|\___|  CLI PRO 4.0.1


  Usage:

    $ ionic <command> [<args>] [--help] [--verbose] [--quiet] [--no-interactive] [--no-color] [--confirm] [options]

  Global Commands:
   ...
  Project Commands:

    build .................... Build web assets and prepare your app for any platform targets
    cordova <subcommand> ..... Cordova functionality (subcommands: build, compile, emulate, platform, plugin, prepare,
                               requirements, resources, run)

    serve .................... Start a local dev server for app dev/testing (alias: s)
    ssl <subcommand> ......... (experimental) Commands for managing SSL keys & certificates (subcommands: generate)

不知道它到底想要什么，语法没有改变（仍然ionic cordova $something）同时，我已经降级了......：/

有同样的问题。修复方法是全局安装 ionic CLI：

作为开发人员用户，从您的 ionic 项目根目录执行以下命令：

npm uninstall ionic

然后作为用户“root”执行以下操作：

npm i -g ionic@latest

之后，您应该可以使用新的 ionic CLI 版本 4.0.1

我面临同样的问题。

解决方法：降级到旧版本 npm i -g ionic@3.20.0

将 --no-interactive 参数添加到您的 ionic cordova 命令以忽略更新问题
