ImportError:没有名为“setuptools.build\u meta”的模块

Question

我很难弄明白这一点——在尝试安装软件包（本例中是zipline）时，它很难找到setuptools.build_元文件，我在site packages\setuptools目录中确实有这个文件。尽管我很无知，但我还是尝试直接将此文件放入站点packages\pip\u vendor\pep517，没有任何更改。我相信这很简单，但我看不出来。任何帮助都将不胜感激！ 追溯如下

Answer 1

我通过将setuptools版本升级到最新版本解决了此问题：

    sudo /usr/bin/python3.9 /usr/bin/pip3 install setuptools==58.0.4

其他版本：

/usr/bin/python3.9 /usr/bin/pip3  version
pip 20.0.2 from /usr/lib/python3.9/dist-packages/pip (python 3.9)

/usr/bin/python3.9  version
Python 3.9.5

lsb_release -d

Answer 2

在我的例子中，我使用python -m pip install pip==9.0.1将我的pip版本降级到9.0.1，它对我起了作用

Answer 3

因此，对于有相同错误的人，我通过直接下载包并删除pyproject.toml文件，然后在终端/cmd中删除cd path\setup.py和“pip install.”来解决这个问题
