我一直试图在我的机器上设置 YouCompleteMe，除了一个小问题，我大部分时间都在那里。当我将 acout用于 simplecout << "Hello world!" << endl;时，YCM 将cout、 first<<和 string 突出显示为错误，告诉我：二进制表达式的操作数无效（'ostream'（又名'int'）和'const char *'）。
我知道我的程序是正确的。它编译并运行。什么可能导致这种行为？
如果我遗漏了任何信息，请告诉我。
谢谢！
编辑：我的 .ycm_extra_conf.py 文件是这样的：

import ycm_core

# compilation database set (by default, one is not set).
# CHANGE THIS LIST OF FLAGS. YES, THIS IS THE DROID YOU HAVE BEEN LOOKING FOR.
