在 Python 中安装包时出现已弃用的轮错误

Question

我正在使用 Python 3-6.10，该包受Pycld2. 但是当我pip install pycld2在命令提示符或 Jupyter Notebook 中调用时，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，似乎是轮子有问题（我不知道如何解决），ValueError编码和命令错误退出状态1有问题。我不知道它们是否都相同问题。我已点击链接https://github.com/pypa/pip/issues/8368，但仍然找不到解决方案。

此问题已在https://github.com/aboSamoor/pycld2/issues/23上报告。作为解决方法，您可以使用 GitHub 中的源代码。下面的提交指向 0.42 版本 pycld2 的 Zip 存档。
