Vim YouCompleteMe异常

异常信息如下：

The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). 
Unexpected error while loading the YCM core library. 
Use the ':YcmToggleLogs' command to check the logs.

1.重装YouCompleteMe

python3 YouCompleteMe/install.py --clang-completer --racer-completer

2.安装YouCompleteMe过程中提示cargo异常

ERROR: cargo is required for the Rust completer.

如果提示cargo异常，需要安装cargo，命令如下：

curl -sSf https://static.rust-lang.org/rustup.sh | sh

cargo安装成功后再重试上述步骤1
