OpenSSL development packages not installed
So you are ready to install Node on your Ubuntu box and run
./configure, to which you are greeted by a nasty looking error:
"Could not autodetect OpenSSL support. Make sure OpenSSL development packages are installed. Use configure --without-ssl to disable this message."
You know damn well OpenSSL is installed on the system, but why is
./configure failing to find it?
./configure is looking for something else (libssl-dev), not openssl. Fixing it is a breeze, just run the command below.
sudo apt-get install libssl-dev
You could configure your Node.js installation with "--without-ssl" to get past the
./configure error, but you will end up without the
crypto module - not recommended at all!
Whichever OS you are on, just make sure you have libssl-dev installed.
