VIM:在 python 模式下使用 python3 解释器 [英] VIM: Use python3 interpreter in python-mode

问题描述

我最近切换到 vim 并使用 本 教程.之前，我使用 这篇 文章.

I have recently switched to vim and configured it for Python-programming using this tutorial. Before, I have made sure that vim supports python3 (vim --version shows +python/dyn and +python3/dyn) using this article.

但是当从 python-mode 执行文件时，仍然选择了 python2.7 解释器.

But when executing a file from python-mode, still the python2.7 interpreter is chosen.

如何配置 vim(或 python 模式)以在 python3 解释器上运行文件?

How can I configure vim (or the python-mode) to run files on the python3 interpreter?

我的操作系统是 Ubuntu 14.04 x64.

My OS is Ubuntu 14.04 x64.

推荐答案

尝试将其添加到您的 .vimrc 文件中

Try adding this to your .vimrc file

let g:pymode_python = 'python3'

我在帮助文档中找到了这个.在 vim 类型中:

I found this in the help docs. In vim type:

:help python-mode

默认情况下，vim 不支持 python3 编译，所以当我尝试这个时，我遇到了各种各样的错误......这告诉我它正在尝试使用 python3.但是如果你的 vim --version 输出显示 +python3 你应该没问题.

By default, vim is not compiled with python3 support, so when I tried this, I got all kinds of errors... Which tells me it's trying to use python3. But if your vim --version output shows +python3 you should be good.

默认情况下，Ubuntu 14.04 不支持 +python3.并且由于限制，您不能同时拥有 python2 和 python3 支持.

By default, Ubuntu 14.04 doesn't come with +python3 support. And due to limitations, you can't have both python2 and python3 support.

所以，你必须编译支持 python3 的 vim.

So, you have to compile vim with python3 support.

这些是对我有用的步骤:从 linux 命令行:

These are the steps that worked for me: From a linux command line:

安装软件包

sudo apt-get install checkinstall mercurial python-dev python3-dev ruby ruby-dev libx11-dev libxt-dev libgtk2.0-dev libncurses5 ncurses-dev

获取最新版本的vim

hg clone https://vim.googlecode.com/hg/ vim

配置

cd vim
./configure \
--enable-perlinterp \
--enable-python3interp \
--enable-rubyinterp \
--enable-cscope \
--enable-gui=auto \
--enable-gtk2-check \
--enable-gnome-check \
--with-features=huge \
--enable-multibyte \
--with-x \
--with-compiledby="xorpd" \
--with-python3-config-dir=/usr/lib/python3.4/config-3.4m-x86_64-linux-gnu \
--prefix=/opt/vim74

编译

make

测试一下

make test

安装

sudo checkinstall

链接包

sudo ln -s /opt/vim74/bin/vim /usr/bin/vim-py3

现在，您拥有两个版本的 vim

Now, you have both versions of vim

要使用普通的 vim (python2) 输入 vim file.py

To use normal vim (python2) type vim file.py

使用带有python3支持类型的vim vim-py3 file.py

To use vim with python3 support type vim-py3 file.py

如果你只想要python3版本，那么你只需要链接到新的vim

If you just want the python3 version, then you only need to link it to the new vim

ln -s /opt/vim74/bin/vim /usr/local/bin/vim

如果你想切换回python2版本，去掉链接

And if you want to switch back to the python2 version, remove the link

rm /usr/local/bin/vim
