无法从install\u requires安装依赖项

Question

我想在我的setup.py中有以下依赖关系：

setup(
    ...
    install_requires=[

        'pcapy>=0.10.0',
    ],
    ...
)

但是pcapy无法使用tox加载：

^{pr2}$

无论解决方案是什么，每次都是同一个问题。在

默认情况下，它不想从pypi加载0.10.3版本（参见下面的pip日志）。在

如果我使用github上指向最新版本的dependency_链接

setup(
   ...
    install_requires=[
        'pcapy==0.10.8',
    ],
   dependency_links = ['http://github.com/CoreSecurity/pcapy/tarball/master#egg=0.10.8']
   ...
)

返回相同的pip日志。在

有什么想法吗？在

PS1:PIP由tox用以下命令调用

install_command = pip install --allow-external pcapy --allow-unverified pcapy {opts} {packages}

PS2:PIP日志错误
