Emacs中的Python 2和3都是如此

I have been using Emacs to write Python 2 code. Now I have both Python 2.6 and 3.0 installed on my system, and I need to write Python 3 code as well.

我一直在使用Emacs编写Python 2代码。现在我的系统上安装了Python 2.6和3.0，我也需要编写Python 3代码。

Here is how the different versions are set up in /usr/bin:

以下是在/ usr / bin中设置不同版本的方法：

python -> python2.6*
python2 -> python2.6*
python2.6*

python3 -> python3.0*
python3.0*

Is there any way to set this up so that Emacs uses the correct version of Python, depending on which language I am using? For instance, C-c C-c currently runs the buffer, but it always calls python2.6, even if I am writing Python 3 code.

有没有办法设置它，以便Emacs使用正确版本的Python，具体取决于我使用的语言？例如，C-c C-c当前运行缓冲区，但它总是调用python2.6，即使我正在编写Python 3代码。

If you are using python-mode.el you can try to change py-which-shell. In order to do this on a per-file basis you can put

如果您使用的是python-mode.el，可以尝试更改py-which-shell。为了在每个文件的基础上执行此操作，您可以放置

# -*- py-which-shell: "python3"; -*-

at the first line of your file - or at the second line if the first line starts with #!. Another choice is to put

在文件的第一行 - 如果第一行以＃！开头，则在第二行。另一个选择是放

# Local Variables:
# py-which-shell: "python3" 
# End:

at the end of your file. Perhaps you should give the full path to python3 instead of just "python3".

在你的文件的末尾。也许你应该给python3的完整路径而不仅仅是“python3”。
