安装失败 requirements.txt 但可以使用 pip install
Install fails with requirements.txt but works with pip install
使用 requirements.txt 与直接使用 pip 安装相比，我看到了一些奇怪的行为。希望你能对此有所了解。
这可能与这个未回答的问题相同：pip install -r requirements.txt fails on scipy, but works when run manually line-by-line
Python 2.7.6
Django 1.6.11
当我像这样使用 requirements.txt 安装 mailchimp3 时：
sudo /usr/local/python/django/bin/pip install -r config/myvr/requirements.txt
安装失败，我看到：

这必须使用要求文件安装，而不是直接为我们的生产环境安装。你有没有机会知道这里有什么？
您还需要其他信息吗？
无法查看您的错误消息，但您可以检查您的 requirements.txt 是否包含依赖于同一文件中所列包的包。假设 req 文件包含 pack1 和 pack2，如果稍后调用 pack1 import pack2 和 pack2，则安装将失败。我遇到了问题，这是一个类似的 problem on github
问题是 requirements.txt 文件中存在对 lxml 的依赖关系，并且该依赖关系设置为在没有线程的情况下安装，因此它看起来像这样
lxml==3.5.0 --install-option='--without-threading'
任何时候通过 --install-option（或 --build-options 或 --global-options），将禁用所有轮子。
在 mailchimp3 的情况下，它需要轮子才能正确安装。
我们的解决方案是将 lxml 的安装移动到单独的构建步骤中。
