在 Python 中安装 package 时出现 Deprecated wheel 错误

Question

I am using Python 3-6.10, package which is supported by Pycld2 . But when I call pip install pycld2 in command prompt or in Jupyter Notebook, the same message appears:

**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.**

From what I understand, it seems that there is a problem with the wheel (I don't know how to solve that), a problem with ValueError encodings and command error exit status 1. I don't know whether they are all the same problem. I have followed the link https://github.com/pypa/pip/issues/8368 and still can't find the solution.

This issue has been reported at https://github.com/aboSamoor/pycld2/issues/23 . As a workaround, you can use the sources from GitHub. The commit below points to a Zip archive of the 0.42 version of pycld2.

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