Answer 1

Andrei's answer worked for me, however I ran into a huge roadblock when trying to reinstall Ruby 1.9.3. Because I had installed a new version of Xcode since installing 1.9.3 I was unable to reinstall until I opened the Xcode Preferences and installed the Command Line Tools from the Downloads tab.

Answer 2

Andrei's answer didn't work for me on Mac OSX 10.8.3. I had reinstalled openssl to install ruby 2.0 some time ago and since then always got this error. I fixed it thanks to Andrei's answer and instructions from the Rails project.

I ran:

$ rvm -v
$ rvm get head
# Installation of latest version of rvm...
$ rvm -v
# rvm 1.19.5 (master)
$ rvm osx-ssl-certs status all
# Certificates for /usr/local/etc/openssl/cert.pem: Old.
# Certificates for /Users/mpapis/.sm/pkg/versions/openssl/0.9.8x/ssl/cert.pem: Old.
$ sudo rvm osx-ssl-certs update all
# Updating certificates...

Then I checked if the certificates were correctly updated by running rvm osx-ssl-certs status all again but /usr/local/etc/openssl/cert.pem was still not updated. I don't know if that was necessary but I did the following:

$ cd /usr/local/etc/openssl/
$ curl -O http://curl.haxx.se/ca/cacert.pem
$ mv cacert.pem cert.pem

After that the problem was fixed. Hope that helps someone else who runs into the same issue.

Answer 3

I've fixed this on Mac OS X Lion 10.7.4 with this solution:

$ rvm remove 1.9.3 (or whatever version of ruby you are using)
$ rvm pkg install openssl
$ rvm install 1.9.3 --with-openssl-dir=$rvm_path/usr

after this you will need to download the missing cacert.pem file:

$ cd $rvm_path/usr/ssl
$ sudo curl -O http://curl.haxx.se/ca/cacert.pem
$ sudo mv cacert.pem cert.pem

Answer 4

For Windows 7: the above solution link of Neil Hoff (Fix for Windows: https://gist.github.com/867550) did not work for me.

Here is what works:

Using cmd.exe:

curl -o c:\cacert.pem http://curl.haxx.se/ca/cacert.pem
set SSL_CERT_FILE=c:\cacert.pem

using msysgit bash:

curl -o /c/cacert.pem http://curl.haxx.se/ca/cacert.pem
export SSL_CERT_FILE=/c/cacert.pem

If you do not have curl on your windows 7 command line get it here: http://www.confusedbycode.com/curl/#downloads
