【问题描述】：

在项目期间我想效仿（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命令，但它不再识别命令ionic cordova emulate ios：

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

  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)
    doctor <subcommand> ...... Commands for checking the health of your Ionic project (subcommands: check, list, treat)

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

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

【问题讨论】：

对我来说工作正常。你能仔细检查一下你是否在全球范围内安装了cordova？
但它在以前的版本中对我有用，并且在我升级后，为什么无法正确安装 Cordova？

标签： cordova ionic-cli

【解决方案1】：

遇到了同样的问题。解决方法是全局安装 ionic CLI：

作为开发者用户，从您的 ionic 项目根目录执行以下操作：

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 4.0.1 版

【解决方案2】：

我也面临同样的问题。

解决方法：降级到旧版本 npm i -g ionic@3.20.0

在您的 ionic cordova 命令中添加 --no-interactive 参数以忽略更新问题

【讨论】：

是的，在发布这个问题后我已经降级了......一切正常 - 但我想跟上更新......如果我会被抛在后面这么久，东西会停止工作：/
