无法在 virtualenv 中安装较旧的 wxPython（无法解压文件/无法确定存档格式）
Unable to install older wxPython within virtualenv (Cannot unpack file / Cannot determine archive format)
在基于 Python 2.6.6 构建的 virtualenv 中， 我正在尝试 pip install 2.8 .10.1 2.6 unicode dmg 发现 here 因此：
pip install -Iv http://sourceforge.net/projects/wxpython/files/wxPython/2.8.10.1/wxPython2.8-osx-unicode-2.8.10.1-universal-py2.6.dmg/download
当然，URL 是一个猜测。
我得到（将日志一分为二）：

"There was an error checking the latest version of pip"重要吗？
pip 是 virtualenv 自己的：
/Users/Pyderman/Downloads/Pyderman/venv/bin/pip --version
pip 7.1.2 from /Users/Pyderman/Downloads/Pyderman/venv/lib/python2.6/site-
packages (python 2.6)
我不认为错误检查版本对您的问题很重要（这只是 pip 试图自我更新）但它导致了错误。也许 Python 的旧版本不支持所需的 SSL 设置？您可以使用以下方式禁用此更新检查：
pip install -Iv http://sourceforge.net/projects/wxpython/files/wxPython/2.8.10.1/wxPython2.8-osx-unicode-2.8.10.1-universal-py2.6.dmg/download --disable-pip-version-check
