我尝试安装一些软件包，例如 pycadf。它因以下错误而失败:
Searching for pycadf>=0.4.1
Reading https://pypi.python.org/simple/pycadf/
Best match: pycadf 0.5.1

Adding UNKNOWN 0.0.0 to easy-install.pth file

看起来它从 pypi 获取包，将其安装为“未知”。它不会发生在每个包裹上。 setuptools-5.5.1 安装在我的环境中。
要解决的任何输入都会有所帮助。
最佳答案
我遇到了，看起来像，同样的问题。我的解决方案是更新设置工具。
关于使用 pip 将 Python 包安装为 UNKNOWN，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25265334/
