pip install错误:安装脚本指定了绝对路径 [英] pip install Error: setup script specifies an absolute path

问题描述

我遭受一种奇怪的点子行为. 打电话

I suffer a strange behaviour of pip. Calling

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

通常可以使用，但是在某些软件包上，它会以异常方式失败

generally works, but on some packages it fails in an abnormal way

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

    setup() arguments must *always* be /-separated paths relative to the

setuptools-git显然已安装，并且我发现了有关此错误的零信息，尽管我被这个问题打了十二遍. 我找不到它为什么抱怨拥有绝对路径的原因，因为它是产生绝对路径的那个.

setuptools-git is obviously installed, and I found zero information on this bug, though I've been struck by this a dozen times. I can't find why it complains of having absolute paths since it's the one generating them.

推荐答案

如果在setup.py中存在include_package_data=True，则由项目的egg-info中的SOURCES.txt文件中指定的绝对路径引起.在这种情况下，'django_inplaceedit.egg-info/SOURCES.txt'包含字符串/tmp/pip-rl1_7G-build/AUTHORS.rst，这是无效的绝对路径.在某些情况下，pip和/或setuptools可能会将文件的完整路径从源树放入文件中.我还不能有效地重现此问题，但是我怀疑setup.py中的include_package_data标志会加剧此问题.要解决此问题，只需在egg-info目录中删除该SOURCES.txt文件，然后从源目录再次重新运行setup.py install.

This is caused by an absolute path specified in a SOURCES.txt file within the project's egg-info, if include_package_data=True is present in setup.py. In this case, 'django_inplaceedit.egg-info/SOURCES.txt' contains the string /tmp/pip-rl1_7G-build/AUTHORS.rst, an invalid absolute path. Under some circumstances either pip and/or setuptools may put in the full path of a file from a source tree into it. I have not been able to effectively reproduce this yet, but I suspect the include_package_data flag in setup.py aggravates this issue. To fix, simply just nuke that SOURCES.txt file in the egg-info directory and rerun setup.py install again from the source directory.
