python - 如何让 Vim 识别 Python3 语法？

Question

我搜索了相关帖子并尝试了几种方法，但在使用 Python3 语法时，我仍然在 Vim 中收到语法错误。

收到错误的代码:

types_of_people = 10; f"There are {types_of_people} types of people."

运行 $ vim --version 的输出:

$ vim --version

你可能注意到上面的 Vim 包括 python3 而不是 python

我已经使用以下方法重新安装了 Vim:

$ brew uninstall vim
$ brew install vim --with-python3

我还尝试将 python 别名为我的 Python3 版本:

$ alias python='python3.6'

我的路径:

$ echo $PATH  
/Library/Frameworks/Python.framework/Versions/3.6/bin:/Users/garythegoat/.rbenv/shims:/usr/bin/python:/usr/local/heroku/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin:/usr/local/go/bin:/Users/garythegoat/golang/bin

:echo has('python') 返回 1

:echo has('python3') 返回 0

感谢任何建议

这是一个难题，因为这与您的操作系统配置的默认 python 有关。

我找到的最有用的相关问题是this one .

两种解决方案都对我有用:

1. 使用 virtualenv 设置虚拟环境.这很累人，因为每次需要打开 vim 时都必须启动虚拟环境。

2. 添加 let g:syntastic_python_python_exec = 'python3' 到 .vimrc 配置文件。我不确定您的配置是否基于 syntastic 插件，但这是最糟糕的调查。
