Changing python interpreter for emacs

提问by sam

Emacs uses an older version of python(2.3) i have for the default python mode, is there a way for me to tell emacs to use the newer version that i have in my home directory?

Emacs 使用旧版本的 python(2.3) 我有默认的 python 模式，有没有办法告诉 emacs 使用我在主目录中的新版本？

btw I'm using a red hat distro and dont have root privileges.

顺便说一句，我使用的是红帽发行版并且没有 root 权限。

It is good habit to check customize-groupof things you wanna tweak. Just do:

检查您想要调整的自定义组是一个好习惯。做就是了：

M-x customize-group RET python RET

you've got now multiple options of which one should be interesting:

您现在有多种选择，其中一个应该很有趣：

Python Python Command

You can customize it there and Save for further sessions.

您可以在那里对其进行自定义并保存以供后续会话使用。

Via .emacs:

通过.emacs：

Try to add to your ~/.emacsfile:

尝试添加到您的~/.emacs文件中：

(setq python-python-command "~/your/python/bin-dir/python")

or

或者

Via the shell environment:

The python command that is run by Emacs is typically python, so you can try the simple approach of changing your path:

python-python-commandis for the older "loveshack python.el". For recent versions of Emacs, which use "gallina python.el", use the variable python-shell-interpreter.

python-python-command适用于较旧的“loveshack python.el”。对于使用“gallina python.el”的最新版本的 Emacs，请使用变量python-shell-interpreter.

(setq python-shell-interpreter "/path/to/python")

On Windows 10, I had two versions of Python installed:

在 Windows 10 上，我安装了两个版本的 Python：

1. v3.5 installed under C:\ProgramData\chocolatey\bin
2. v3.6 installed under C:\Program Files\Python36\

1. v3.5下安装 C:\ProgramData\chocolatey\bin
2. v3.6下安装 C:\Program Files\Python36\

Emacs was using v3.5 but I preferred for it to use v3.6. Therefore, I did the following to correct this by editing my Environment Variables:

Emacs 使用的是 v3.5，但我更喜欢它使用 v3.6。因此，我通过编辑我的环境变量做了以下工作来纠正这个问题：

1. Start -> Type in "environment variables"
2. Select Edit the system environment variables-> Environment Variables...
3. Under System variables, select Pathvariable -> Edit...-> New
4. Add the path to your desired Python directory
5. Click Move upto place the new filepath above whatever the other Python directory.

1. 开始 -> 输入“环境变量”
2. 选择Edit the system environment variables->Environment Variables...
3. 在 下System variables，选择Path变量 -> Edit...->New
4. 将路径添加到所需的 Python 目录
5. 单击Move up以将新文件路径置于其他 Python 目录之上。

In my case for #4 & #5 above, I added C:\Program Files\Python36\(v3.6 directory) and then moved it above C:\ProgramData\chocolatey\bin(v3.5 directory)

在我上面的#4 & #5 的情况下，我添加了 C:\Program Files\Python36\（v3.6 目录）然后将它移到上面C:\ProgramData\chocolatey\bin（v3.5 目录）
