Question

在virtualenv内置的 Python 2.6.6 中，我正在尝试pip install 2.8.10.1 2.6 unicode dmg found { {3}}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有点猜测。

我得到（将日志分成两部分）：

“检查最新版本的pip时出错”是否显着？

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)

Answer 1

我不认为错误检查版本对您的问题很重要（这只是pip试图更新自己）但它导致了错误。也许旧版本的Python不支持所需的SSL设置？您可以使用以下命令禁用此更新检查：

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

无法在virtualenv中安装旧的wxPython（无法解压缩文件/无法确定存档格式）
