Error installing Python Plugin: ModuleNotFoundError: No module named <module>
Error installing Python Plugin: ModuleNotFoundError: No module named <module>
我正在尝试使用 Poetry 为 Saleor 构建一个 Python 插件，但在 Saleor 上安装该插件时遇到问题。我 运行 poetry add ../social_auth 在 saleor 上安装插件并且它成功了但是当我尝试 运行 Saleor 我得到这个错误：
No module named 'social_auth'

问题是 pyhton 找不到插件源，因为它不在 PYTHONPATH 中，我不得不使用此命令将它添加到 PYTHONPATH 环境变量中：
PYTHONPATH=path/to/plugin
