“ionic serve”失败且没有错误

Question

重置 git head one commit back 并确认 ionic 更新后，ionic serve 在 'build dev started...' 上退出，没有错误：/

我已尝试使用 npm update 从项目结束安装中删除 package.lock.json 和 node_modules 文件夹 - 问题未解决

然后我发现在另一个 ionic 项目上，ionic 也没有工作，有同样的问题。

ionic serve
[WARN] No local CLI detected.
       Starting with CLI 3.6, the CLI must be installed locally to use local CLI plugins.

? Install now? Yes

> npm install --save-dev --save-exact ionic@latest
✔ Running command - done!
[OK] Installed Ionic CLI locally!

Please re-run your command.

Answer 1

重启整台机器解决了这个问题！

编辑（14.aug.2017）：我发现这只是两个 'ionic serve' 进程的冲突。从现在开始，拥有多个 ionic serve 实例就没有问题了，例如当我同时打开两个项目时。此问题在 Starting with CLI 3.6, the CLI must be installed locally to use local CLI plugins. 更新后出现。所以从现在开始，取消其他进程就可以解决问题了。
