Using flatpak-pip-generator resulting in "ERROR: could not find a version" when compiling

Question

完整的日志可以在下面看到。我正在使用 flatpak-pip-generator 和 requirements.txt。如果不使用需求文件，我会得到同样的错误。（我在编译项目时遇到错误）

  ERROR: Command errored out with exit status 1:
   command: /usr/bin/python3 /usr/lib/python3.8/site-packages/pip install --ignore-installed --no-user --prefix /tmp/pip-build-env-myezehl4/overlay --no-warn-script-location --no-binary :none: --only-binary :none: --no-index --find-links file:///run/build/python3-numpy -- 'setuptools<49.2.0' wheel 'Cython>=0.29.21'
       cwd: None

我已经通过锁定我的 python 依赖项的特定版本解决了我的问题（奇怪的是，如果我使用 flatpak-pip-generator，它如何只对我有效）。我还使用了 cppy，因为显然 matplotlib 依赖于它，尽管它似乎没有在依赖轮中明确声明。我的 requirements.txt 文件现在是：

numpy==1.17.3
# matplotlib implicitly requires cppy
cppy==1.1.0
matplotlib==3.1.1
sympy==1.6.2
