我使用pip需求文件来维护项目的依赖项列表.

我现在发现自己必须安装一个库,pip install --install-option='some-setup.py.option' 但 pip freeze不会在输出中记录这些选项,我保存在我的项目中requirements.txt.这会导致问题,因为pip install -r requirements.txt新机器上的简单安装所有依赖项而不为这一个库提供所需的参数,并且我已经失去了简单的往返操作.

所以,我的两部分问题是:

• 有没有办法在pip冻结输出中以某种方式维护pip安装选项？
• 如果没有,有没有办法手动破解需求文件以添加安装选项？pip freeze如果必须的话,我可以失去往返性质,并切换到需求文件的手动维护.我检查了文档,但看不到任何帮助.

不必要但可能有趣的细节如下

我想安装pymongo但没有构建C扩展,所以我可以在基于eventlet的应用程序中异步使用它.

根据需要安装并构建requirements.txt:

(test)day@office:~/test$ pip install pymongo --install-option='--no_ext'
Downloading/unpacking pymongo
  Downloading pymongo-2.1.1.tar.gz (199Kb): 199Kb downloaded

如何使用django与Elastic Benastalk,它也只能在主节点上通过芹菜运行任务？

当我执行时,pip install thumbor我收到以下错误:
