誤差與蟒（MAC）虛擬ENV

我有virtualenv中對MAC ......工作中的問題，這是我做的：誤差與蟒（MAC）虛擬ENV

根本原因是'導入錯誤：dlopen的（/Users/tester/Documents/myproject/foobar/lib/python2.7/lib- dynload/_io.so，2）：符號未找到：__PyCodecInfo_GetIncrementalDecoder'。祝你好運。你堅持2.7嗎？或者你可以嘗試更新的版本，如3.5？ –

我正好遇到了同樣的問題。

原來我是使用python-2.7.13降級到2.7.10解決了這個問題。

如果使用的是蟒蛇，你可以做，通過運行：
$ conda install python=2.7.10
