【问题描述】：
我一直在尝试在我的机器上设置 YouCompleteMe，除了一个小问题外，我大部分时间都在那里。当我将cout 用于简单的cout << "Hello world!" << endl; 时，YCM 会突出显示cout，第一个<< 和字符串作为错误，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 os
import ycm_core
# These are the compilation flags that will be used in case there's no
# compilation database set (by default, one is not set).
# CHANGE THIS LIST OF FLAGS. YES, THIS IS THE DROID YOU HAVE BEEN LOOKING FOR.
flags = [
'-Wall',
'-stdlib=libc++',
'-std=c++11',
'-x', 'c++',
# This path will only work on OS X, but extra paths that don't exist are not
# harmful
'-isystem', '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/7.0.2/include'

# Set this to the absolute path to the folder (NOT the file!) containing the

【问题讨论】：
-
您是否包含了正确的标题并添加了 using 声明/指令？
-
好像你忘记在
.ycm_extra_conf.py文件中添加编译标志 -
@DennisS 好吧，我已经添加了一个 .ycm_extra_conf.py 文件，并将其作为全局后备添加到 ~/.vimrc 中，但我不知道从哪里开始编译器标志。到目前为止我有
'-Wall', '-std=c++11', '-stdlib=libc++', '-x', 'c++', '-isystem', '/usr/lib/c++/v1' -
@HeliosPanoptes 您是否收到了来自 vim 的确认请求，然后您试图从您的 C++ 项目中打开任何文件？类似
Found /path/to/file/.ycm_extra_conf.py. Load? -
@DennisS 我没有收到确认请求，但我认为那是因为它是全局后备。它确实有效，只是在标准库上搞砸了一点。
