在 Python 中安装包时出现弃用的 wheel 错误

Question

我正在使用 Python 3-6.10，Pycld2 支持的软件包。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，轮子似乎有问题（我不知道如何解决）， ValueError 编码和命令错误退出状态 1 的问题。不知道是不是都是同一个问题。我已经按照 link https://github.com/pypa/pip/issues/8368 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，您可以使用来自 GitHub 的源代码。下面的提交指向 0.42 版本的 pycld2 的 Zip 存档。
