### 检测是否安装GCC
gcc --version

if [ $? != 0 ]
then
	echo 'Before you proceed, make sure that your system has a C compiler'
	exit 0
fi

# 显示python版本
echo "Python3 Version:"
python3 -V

if [ $? != '0' ]
then
	echo 'Before you proceed, make sure that your system has a python3'
	exit 0
fi

### 设置变量
LATEST='libsodium-*'

echo 'Server IP address'
read server_ip
echo 'Port number to be used'
read server_port
echo 'ShadowSocks password'
read password

	then
		echo 'Encryption method : aes-256-cfb'
