CentOS 7安装chacha20加密，遇到C preprocessor “/lib/cpp” fails sanity check解决方法

根据YouTube UP主 沙漠狐（地址点我）脚本在CentOS7上安装chacha20，遇到C preprocessor “/lib/cpp” fails sanity check。原脚本如下（略有修改）：

yum install build-essential make
wget https://download.libsodium.org/libsodium/releases/LATEST.tar.gz
tar xf LATEST.tar.gz && cd libsodium-stable
./configure && make -j4 && make install
ldconfig

遇到报错C preprocessor “/lib/cpp” fails sanity check。解决方法，运行如下脚本：

yum -y install glibc-kernheaders
