Got this error after starting amber watch (very new to web dev)

Can you compile a simple crystal program?

Try this:

crystal init app hello
cd hello
shards build
bin/hello

[faustinoaq]

Analyzing your logs, I think this is an openssl issue on macOS, see: crystal-lang/crystal#6875

[oshybrid]

Did the trick. Thank you

Try this:
echo 'export PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig' >> ~/.bash_profile
