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

Question

我正在研究一个既是库又是应用程序的Python/C++项目。我具有运行

$ pip install -r requirements.txt 

问题两次给了我下面的错误（这是第二次运行）：

$ pip install -r requirements.txt

我需要运行它多次可能的，因为pip install会成为Makefile的一部分或者缓解应用程序最终用户的生活。 我发现只有one post与此问题，但没有解决方案的路径。

Answer 1

这是发生在我身上的，因为在错误的地方有一个myProject.egg-info文件夹，Pip在尝试卸载它时似乎崩溃了。我删除了这个，reran pip install -r requirements.txt，并且该文件夹被安装到指定的正确位置。
