我已经下载了pyocd并成功构建了它。现在我可以从任何位置从命令行运行该工具。但是，当尝试使用 pexpect 运行它时，它会显示以下错误：

Traceback (most recent call last):

pkg_resources.DistributionNotFound: The 'pyocd==0.14.1.dev277+dirty' distribution was not found and is required by the application

请帮助理解什么是错误的以及为什么它可以从命令行工作？

问题是我试图生成pyocd.exe并且pexpect找不到包。我将线路更改为python -m pyocd，它工作正常。我是 Python 新手，错误地认为 exe 是编译代码，就像 Windows 中的其他 exe 文件一样。但是，这只是使用 Python 运行包的指令。
