python - 导入错误 : No module named 'setuptools.build_meta'

Question

我无法弄清楚这一点——在尝试安装包(在本例中为 zipline)时，很难找到我在 site-packages\setuptools 目录中拥有的 setuptools.build_meta 文件。像我一样无知，我尝试将此文件直接放入 site-packages\pip_vendor\pep517 中，没有任何更改。我敢肯定这很简单，但我没有看到。任何帮助，将不胜感激! 回溯如下。

所以对于遇到相同错误的任何人，我通过直接下载包并删除 pyproject.toml 文件，然后 cd path\setup.py 和“pip install”来解决这个问题。在终端/cmd 中。
