pip install requirements.txt 因 AssertionError 失败：Egg-link 与安装位置不匹配

Question

我正在开发一个既是库又是应用程序的 Python/C++ 项目。我遇到了运行问题

$ pip install -r requirements.txt

两次给我以下错误（这是第二次运行）：

$ pip install -r requirements.txt

我需要尽可能多地运行它，因为pip install 将成为 Makefile 的一部分或简化应用程序的最终用户的生活。 我发现只有 one post 有这个问题，但没有找到解决方案的途径。

Answer 1

这发生在我身上，因为 myProject.egg-info 文件夹在错误的位置，Pip 在尝试卸载它时似乎摔倒了。我删除了这个，重新运行pip install -r requirements.txt，文件夹安装到指定的正确位置。
