今天我在我的应用程序中看到一个奇怪的错误，它是这样的

FileSystemException: FileSystemException: Getting current working directory failed, path = '' (OS Error: Too many open files in system, errno = 23)

我的应用程序有大量资产，也许是这个问题的原因？

这感觉像是两个不同的问题。一个是我们持有的包：Mac 上的测试代码，并试图一次驱动太多的测试

如何更改 macOS 上的打开文件限制？

Mac OS 一次可以打开多少个文件的默认限制相当低。如果遇到此限制，请使用以下ulimit命令增加可用文件处理程序的数量：

ulimit -S -n 2048

如果您使用 Travis 或 Cirrus 进行测试，请通过将同一行分别添加到 flutter/.travis.yml 或 flutter/.cirrus.yml 来增加它们可以打开的可用文件处理程序的数量。
