在Python中安装软件包时不推荐的滚轮错误

问题描述

我正在使用Pycld2支持的Python 3-6.10软件包。 但是，当我在命令提示符或Jupyter Notebook中调用pip install pycld2时，会出现相同的消息：

**ValueError: path '/home/rmyeid/code/pycld2/bindings/encodings.cc' cannot be absolute**
  ----------------------------------------
ERROR: Failed building wheel for pycld2
Running setup.py clean for pycld2
Failed to build pycld2
DEPRECATION: Could not build wheels for pycld2 which do not use PEP 517. 
pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. 
**A possible replacement is to fix the wheel build issue reported above. 
You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.**

据我了解，方向盘似乎有问题（我不知道如何解决）， ValueError编码和命令错误退出状态1出现问题。 我不知道它们是否都是相同的问题。 我已经点击了链接https://github.com/pypa/pip/issues/8368，但仍然找不到解决方法。

解决方法

已在https://github.com/aboSamoor/pycld2/issues/23上报告了此问题。解决方法是，您可以使用来自GitHub的资源。下面的提交指向pycld2的0.42版本的Zip存档。

pip install https://github.com/aboSamoor/pycld2/zipball/e3ac86ed4d4902e912691c1531d0c5645382a726
