linux - YouCompleteMe 不可用 : unable to load Python

Question

我使用 Linux CentOS-7-x86_64 并尝试使用 vundle 安装 YouCompleteMe。我收到错误:

YouCompleteMe unavailable: unable to load Python.

但是，当我输入 vim --version 时，我得到:

并且，当我使用 .configure 安装 vim 时，我包括

--with-features=huge --enable-python3interp --enable-pythoninterp

我该怎么做才能解决这个问题？

Answer 1

我建议你去你的 ~/.vimrc 并在你开始你的插件声明之前将它添加到文件的开头。

if has('python3')
endif

~/.vimrc 示例:

if has('python3')
endif

call plug#begin('~/.vim/plugged')
Plug 'https://github.com/ycm-core/YouCompleteMe.git'
call plug#end

从那里你可以

:PlugInstall 

然后 cd 到你的 YouCompleteMe 目录。如果您安装了 Anaconda，请确保不要将其与它一起安装。

改用/usr/bin python。

例子:

/usr/bin/python3 install.py --all

最后，一旦一切就绪并完成，请重新启动计算机并再次打开 Vim。

我使用 https://github.com/junegunn/vim-plug 安装了 YouCompleteMe但只要你的 vimrc 中有“if”语句，它就应该可以工作。
