【问题描述】：
当我尝试在 Linux 上配置 Firefox 46 时，我收到以下错误：
0:03.58 checking for python2.7... /usr/local/bin/python2.7

我填补了以下错误，我做了一个平分识别导致此问题的补丁：
https://bugzilla.mozilla.org/show_bug.cgi?id=1268251
补丁如下：

我联系了补丁的作者，但他没有找到解决办法。
由于我总是可以配置、编译和安装 Firefox 45 及以下版本，但不能 46（因为这个补丁），这里发生了什么？也许是 virtualenv 问题？
谢谢！
Ps：我的 Python 安装没问题。直到现在我都没有遇到过这种问题。
