使用 pip 将 Python 包安装为未知

Question

我尝试安装一些软件包，例如 pycadf。它失败并出现以下错误：

Searching for pycadf>=0.4.1
Reading https://pypi.python.org/simple/pycadf/
Best match: pycadf 0.5.1
Downloading https://pypi.python.org/packages/source/p/pycadf/pycadf-0.5.1.tar.gz#md5=0386d95acb2045231fbcbe12fcaa2779

Adding UNKNOWN 0.0.0 to easy-install.pth file

Installed /usr/local/lib/python2.7/dist-packages/UNKNOWN-0.0.0-py2.7.egg
error: Could not find required distribution pycadf>=0.4.1

看起来它从 pypi 获取包，并将其安装为“未知”。并不是每个包裹都会发生这种情况。setuptools-5.5.1 安装在我的环境中。

任何需要解决的输入都会有所帮助。

我也遇到了同样的问题。我的解决方案是更新安装工具。
