问题
Since I upgraded to OS X 10.10 Yosemite, I get the following error when trying to install a ruby gem:
ERROR: While executing gem ... (Gem::Exception)
Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources
But when I do which openssl it shows me the path:
/usr/local/bin/openssl
I have uninstalled and reinstalled rvm and ruby but still get the same error.
How do I install Ruby gems?
回答1:
OpenSSL issues with Ruby on Yosemite could be a result of your installed version of Ruby trying to locate OpenSSL certificates in /etc/openssl/certs instead of its new location at /usr/local/etc/openssl/certs. Try reinstalling ruby using the --disable-binary switch so that the source is re-built on your local machine instead of using the pre-compiled binary. For example:
rvm uninstall 2.2.0
rvm install 2.2.0 --disable-binary
回答2:
Looks like the gem installer can't find your openssl.
Try this with your ruby version:
brew install openssl
rvm reinstall 2.3.4 --with-openssl-dir=`brew --prefix openssl`
