“pip install -e”中如何使用“egg=”？

Question

尝试测试可编辑安装，但我不确定如何解释结果。

我故意在这部分打错字egg=，但它仍然能够在没有我帮助的情况下找到鸡蛋：

root@6be8ee41b6c9:/# pip3 install -e git+https://gitlab.com/jame/clientapp.git      
Could not detect requirement name for 'git+https://gitlab.com/jame/clientapp.git', please specify one with #egg=your_package_name

root@6be8ee41b6c9:/# pip3 install -e git+https://gitlab.com/jame/clientapp.git#egg=
Could not detect requirement name for 'git+https://gitlab.com/jame/clientapp.git#egg=', please specify one with #egg=your_package_name

因此，如果我可以把鸡蛋名称搞得这么糟糕，为什么将其留空或设置为空会被视为错误

这是过时的表示法。如今，只要有可能，就应该使用以下符号：

python -m pip install 'ProjecName @ git+https://example.local/repository.git@1.3.1'

我猜，如果该项目是另一个项目的依赖项，那么名称很重要。例如，如果有人想要从APyPI和gitZ安装，但又依赖于.ZA

python -m pip install 'A' 'git+https://example.local/Z.git#egg=Z'

或使用新的符号：

python -m pip install 'A' 'Z @ git+https://example.local/repository.git
