pip install 错误：安装脚本指定了绝对路径

Question

我遭受了 pip 的奇怪行为。 调用

pip install git+https://github.com/username/repo

通常可以，但在某些包上它会以异常方式失败

Downloading/unpacking git+git://github.com/artscoop/django-inplaceedit
  Cloning git://github.com/artscoop/django-inplaceedit to /tmp/pip-rl1_7G-build
  Running setup.py egg_info for package from git+git://github.com/artscoop/django-inplaceedit

Installing collected packages: django-inplaceedit
  Running setup.py install for django-inplaceedit

    error: Error: setup script specifies an absolute path:

        /tmp/pip-rl1_7G-build/AUTHORS.rst

    setup() arguments must *always* be /-separated paths relative to the
    setup.py directory, *never* absolute paths.

setuptools-git 显然已安装，我发现关于此错误的零信息，尽管我已经被这个问题击中了十几次。 我找不到为什么它抱怨有绝对路径，因为它是生成它们的那个。

Answer 1

就我而言，这个问题的解决方案是我的MANIFEST.ini 文件包含静态路径（它不是偶然创建的，对旧鸡蛋进行核对没有帮助）：

错误：

recursive-include resources /*.*

右：

recursive-include resources *.*

?

Answer 2

我遇到了同样的错误并通过注释掉它来修复它

include_package_data=True

在setup.py 模块中

Answer 3

这是由项目的 egg-info 中的 SOURCES.txt 文件中指定的绝对路径引起的，如果 include_package_data=True 存在于 setup.py 中。在这种情况下，'django_inplaceedit.egg-info/SOURCES.txt' 包含字符串 /tmp/pip-rl1_7G-build/AUTHORS.rst，这是一个无效的绝对路径。在某些情况下，pip 和/或setuptools 可能会将来自源树的文件的完整路径放入其中。我还不能有效地重现这一点，但我怀疑setup.py 中的include_package_data 标志会加剧这个问题。要修复，只需在 egg-info 目录中删除 SOURCES.txt 文件，然后从源目录再次运行 setup.py install。
