Question

它似乎自动使用最新版本，我无法在pyinstaller文档中找到答案。
它抱怨我的python2代码语法不正确，但它没有。

Answer 1

也许使用virtualenv或 virtualenvwrapper 使用virtualenv，可以使用不同版本的Python创建单独的环境。 virtualenvwrapper是virtualenv的包装器，它更容易使用。

Answer 2

由于您不愿意像评论那样安装虚拟环境，因此可以采用以下方法：

找到安装python 2.x的路径:(不确定）：/usr/local/lib/python2.7
打开控制台
输入PATH=/usr/local/lib/python2.7:$PATH
键入python --version只是为了检查它是否说V2不是V3
使用python前缀

这不会影响系统路径（控制台的本地路径），因此无需恢复到以前的路径设置。完成后关闭控制台。

另外，请不要使用sudo，因为它不需要它会更改/重置路径，这是您确认时的问题。

当我还有3.5时，如何让pyinstaller使用python 2.7？
