点冻结> requires.txt错误 [英] pip freeze > requirements.txt error

问题描述

我收到以下错误：

$pip freeze > requirements.txt 
Warning: cannot find svn location for distribute==0.6.16dev-r0

这是我的require.txt文件：

This is my requirements.txt file beforehand:

Django==1.3
django-registration==0.7

推荐答案

首先，我会注意到这不是错误，而是一个警告（虽然这是一个严重的）

First, I'd note that is not an error, but rather a warning (though it is a serious one).

这似乎是一个开放的问题，在这个发行页面。当pip正在安装一个持有在不是SVN的存储库上的开发版本时，会出现此问题。问题页面的一个例子是：

This appears to be an open issue in pip, judging by this issue page on the github repository. The problem arises when pip is installing something a development version that is held on a repository that is not SVN. One example that issue page provides:

mkvirtualenv test --no-site-packages
workon test
pip install flask==dev
pip freeze > requirements.txt

它将打印此结果为标准错误：

It will print this result to standard error:

Warning: cannot find svn location for Flask==0.9-devdev-20120114

但文件仍然会有：

## FIXME: could not find svn URL in dependency_links for this package:
Flask==0.9-devdev-20120114
Jinja2==2.6
Werkzeug==0.8.2
wsgiref==0.1.2

但是，我将来无法使用此文件来安装Flask。参见这里：

However, I won't be able to use this file in the future to install Flask. See here:

mkvirtualenv test2 --no-site-packages
workon test2
pip install -r requirements.txt

输出错误：

Downloading/unpacking Flask==0.9-devdev-20120114 (from -r requirements.txt (line 2))
Could not find a version that satisfies the requirement Flask==0.9-devdev-20120114 (from -r requirements.txt (line 2)) (from versions: )
