在一個virtualenv建關的Python 2.6.6，我試圖pip install的2.8.10.1 2.6 Unicode的 DMG發現here從而：無法的virtualenv中安裝舊的wxPython（無法解壓縮文件/無法確定歸檔格式）
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
當然，這個URL是有點猜測的。
我得到（將在日誌中二）：

是 「有一個錯誤檢查最新版本PIP的」 顯著？
點子是的virtualenv自己：
