No package ‘openssl‘ found

Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `openssl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'openssl' found

解决方法

1. 检查是否安装了openssl

sudo apt install openssl

如果还是报错

2.安装

sudo apt-get install libssl-dev
