virtualenv - pip -r 在 vi​​rtualenv 中没有按预期工作

Question

我对 pip 在 vi​​rtualenv 中的行为有一个非常奇怪的问题。

我已经设置了

export PIP_REQUIRE_VIRTUALENV=true
export PIP_DOWNLOAD_CACHE=$HOME/.pip/cache
export VIRTUALENV_DISTRIBUTE=true

现在，当我在我的 virtualenv 中并想要安装我的依赖项时:

pip install -r requirements/_base.txt

(出于测试目的，requirements/_base.txt 只包含:)

Django==1.5

无论如何，当我尝试安装它时，我只得到:

Downloading/unpacking Django==1.5 (from -r requirements/_base.txt (line 1))
Running setup.py egg_info for package Django

warning: no previously-included files matching '__pycache__' found under directory '*'
warning: no previously-included files matching '*.py[co]' found under directory '*'

之后，Django 没有安装。

奇怪的部分来了:当我手动安装 Django 时

pip install Django==1.5

它运行良好(尽管出现了相同的两个警告):

Downloading/unpacking Django==1.5
Running setup.py egg_info for package Django

warning: no previously-included files matching '__pycache__' found under directory '*'
warning: no previously-included files matching '*.py[co]' found under directory '*'

我遇到了类似的问题，并意识到删除版本要求可以解决问题。不知道为什么...
