app crashed - waiting for file changes before starting...

"app crashed - waiting for file changes before starting..."这个报错信息表示应用程序崩溃了，正在等待文件更改后重新启动。这可能是因为在应用程序启动之前，文件发生了一些变化，导致应用程序无法正常启动。

要解决这个问题，有几个可能的步骤可以尝试：
1. 检查是否有其他程序正在使用相同的端口。根据报错信息中的"Starting inspector on 127.0.0.1:9229 failed: address already in use"可以得知9229端口已被占用。可以使用命令行工具（如lsof或netstat）来查找并杀死占用该端口的进程。这样，应用程序就可以在重新启动时使用该端口。

2. 检查应用程序代码中是否存在错误。有时，应用程序崩溃的原因可能是代码中的错误或逻辑问题。可以通过仔细检查代码并调试来查找并修复这些错误。特别是检查与文件更改相关的代码，以确保没有错误导致应用程序崩溃。

3. 如果报错信息中提到了构建过程，可以尝试重新进行构建。根据引用，在构建应用程序时，使用正确的签名和配置是非常重要的。确保正确设置了App Store的签名，而不是ad-hoc provisioning的签名。

需要根据具体情况来确定最佳的解决方法。如果以上方法都没有解决问题，可能需要进一步调查和分析日志或错误报告来找到导致应用程序崩溃的原因。

koa2 服务器出现[nodemon] app crashed - waiting for file changes before starting...

If you are encountering the error message "[nodemon] app crashed - waiting for file changes before starting..." when running your Koa2 server with nodemon, it means that there is an error in your code that is causing the server to crash.

To diagnose the issue, you can do the following:

1. Check the logs: When the server crashes, nodemon should print an error message to the console. Look for this message and see if it provides any clues as to what went wrong.

2. Debug the code: Use a debugger to step through your code and identify the problem. You can set breakpoints in your code using the `debugger` statement, or use a tool like VSCode's debugger to step through the code.

3. Check dependencies: Make sure that all the dependencies required by your server are installed and up-to-date.

4. Check file permissions: If your server is trying to access files, make sure that the appropriate file permissions are set.

5. Check network settings: If your server is trying to connect to external resources, make sure that your network settings are configured correctly.

Once you have identified the issue, you can fix the code and restart the server. If you are still encountering issues, feel free to ask me for further assistance.
