使用emacs（aquamacs）与python 3.2 [英] Use emacs(aquamacs) with python 3.2

问题描述

Mac osx雪豹上的默认python版本是python 2.6.1。我正在学习python 3，所以我必须改变口译员。我已经改变了这个设置，所以它指向 /Library/framework/python.framework/version/3.2/bin/python3.2 。我相信这是我的3.2解释器的安装位置。
当我重新启动Emacs，一切都正常。当我开始翻译时，它说python 3.2：

The default python version on mac osx snow leopard is python 2.6.1. I am learning python 3, so I have to change the interpreter. I have changed the setting in preference, so that it points to /Library/framework/python.framework/version/3.2/bin/python3.2. I believe that is where my 3.2 interpreter is installed. When I restart Emacs, everything works fine. When I start the interpreter, it says python 3.2:

Python 3.2 (r32:88452, Feb 20 2011, 11:12:31) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

但是，当我要求Emacs执行缓冲区时，会显示以下消息：

However, when I ask Emacs to execute a buffer, this message shows up:

execfile(r'/var/folders/yV/yVXYrzONGSaZeoBmB-mdkE+++TI/-Tmp-/python-2180L5f.py') # PYTHON-MODE
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'execfile' is not defined

我不知道如何修复它。它与我的代码无关，因为即使我尝试执行这个消息显示：

I don't know how to fix it. It has nothing to do with my code though, because this message shows up even when I try to execute:

print ("Hello World")

推荐答案

这是一个较长的答案，因为我不得不研究一下。

This is a longer answer, as I had to look into it.

1. 需要在系统上安装Python 3。我已经安装了HomeBrew，所以这涉及到 $ brew install python3 。您可以使用其他方法安装。

1. Python 3 will need to be installed on your system. I already installed HomeBrew, so this involved $ brew install python3. You can install with other methods as well.

我使用一个virtualenv for Python 3.我通过使用 virtualenv - P python3 myproj Aquamacs让你 Mx virtualenv-activate 来设置它。

I use a virtualenv for Python 3. I make a virtualenv by using the virtualenv -P python3 myproj Aquamacs lets you M-x virtualenv-activate to set it.

在 python-mode.el 文件中存在一些问题，一个Lisp文件隐藏在您的 /Applications/Aquamacs.app/Contents/Resources中/口齿不清/ aquamacs /编辑模式/蟒模式。 Andreas Roehler 修补了 bug 。如果主要的蟒蛇模式页面仍然在6.1.2版本，那么您将下载一个新的 python-mode.el 这里，并将其复制到现有版本。

There were problems in the python-mode.el file, a lisp file hiding down in your /Applications/Aquamacs.app/Contents/Resources/lisp/aquamacs/edit-modes/python-mode. Andreas Roehler patched the bug. If the main python-mode page is still on version 6.1.2, you download a new python-mode.el here and copy it over your existing version.

现在应该工作。
