Question

我创建了我的第一个包。当我尝试在新创建的virtualenv中使用pip安装它时，我收到一条错误，指示无法导入库，但它们已添加到install_requires中的setup.py字段中。如果我在vierualenv之外做，一切都好。我的setup.py在这里：https://github.com/tdi/pyPEPA/blob/dev/setup.py

重现错误：

mkvirtualenv something -p /usr/bin/python3
workon something
pip install pypepa

Downloading/unpacking pypepa
 Running setup.py egg_info for package pypepa

Answer 1

您的安装脚本导入pypepa，导入pypepa.pepa_model导入pyparsing，但尚未安装pyparsing（我们甚至没有完成运行安装脚本以了解依赖项）。解决方案是在pypepa和setup.py中重复版本号（这样你可以删除导入），或者不在__init __中导入PEPAModel。py。

Answer 2

Python3使用distutils，setup()将使用requires关键字参数。来自the docs：

可以通过向setup（）提供 requires 关键字参数来指定对其他Python模块和包的依赖性。

将 setup.py 脚本中的install_requires更改为requires。

Python包似乎忽略了我的要求
