从pexpect运行已安装的软件包

Question

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，它显示以下错误：

Traceback (most recent call last):
  File "c:\Users\elephant\AppData\Local\Programs\Python\Python37-32\Scripts\pyocd-script.py", line 6, in <module>

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

请帮助从命令行了解错误及其原因？

问题是我试图生成pyocd.exe并且pexpect无法找到包。 我将行改为python -m pyocd ，它运行正常。 我是Python的新手，并错误地认为exe是编译代码作为Windows中的其他exe文件。 但是，这只是使用Python运行包的指令。
