本文解决了一个常见的YouCompleteMe插件在Vim编辑器中出现的错误，即'undefined symbol: clang_getCompletionFixIt'。通过修改安装脚本中的Python版本设置为Python3，可以成功解决该问题，确保了代码补全功能的正常运行。

- ERROR - /home/admin/.vim/bundle/YouCompleteMe/third_party/ycmd/ycm_core.so: undefined symbol: clang_getCompletionFixIt
Traceback (most recent call last):
File "/home/admin/.vim/bundle/YouCompleteMe/third_party/ycmd/ycmd/utils.py", line 639, in ImportAndCheckCore
ycm_core = ImportCore()
File "/home/admin/.vim/bundle/YouCompleteMe/third_party/ycmd/ycmd/utils.py", line 630, in ImportCore
import ycm_core as ycm_core
ImportError: /home/admin/.vim/bundle/YouCompleteMe/third_party/ycmd/ycm_core.so: undefined symbol: clang_getCompletionFixIt

解决办法：在YouCompleteMe目录下运行install.sh

cd  ~/.vim/bundle/YouCompleteMe
./install.sh

这里可能会报错，是关于python版本的问题，只需要将install.sh里的python/python2全部改成python3即可。

#!/bin/sh

echo "WARNING: this script is deprecated. Use the install.py script instead." 1>&2


SCRIPT_DIR=$(dirname $0 || exit $?)

command_exists() {
  command -v "$1" >/dev/null 2>&1 ;
}

PYTHON_BINARY=python3
if command_exists python3; then
  PYTHON_BINARY=python3
fi

$PYTHON_BINARY "$SCRIPT_DIR/install.py" "$@" || exit $?
