Answer 1

I'm totally new to Ruby and Sass. I didn't want to risk security and I'm on a Windows machine. I had already installed latest ruby, but kept getting the same error message as the OP when trying to run gem install sass at the command prompt.

Here's what solved the problem for me.

Go to: https://rubygems.org/pages/download and follow the instructions on the page starting here (for manual installation):

If you don't have any RubyGems installed, there is still the pre-gem approach to getting software, doing it manually:

1. Download from above (URL above)
2. Unpack/unzip into a directory and cd there (into the directory you unzipped it)
3. Install with: ruby setup.rb (at the command line type that command. You may need admin/root privilege)

After I installed ruby gems, I opened Ruby command prompt (using Start Command Prompt with Ruby from the start menu) and ran the command gem install sass and it worked:

C:\Users\chris>gem install sass
Fetching: sass-3.4.22.gem (100%)
Successfully installed sass-3.4.22
Parsing documentation for sass-3.4.22
Installing ri documentation for sass-3.4.22
Done installing documentation for sass after 36 seconds
1 gem installed

Wanted to detail it as much as possible for other newbies like me. Hope this helps someone.

The first step to Rubygems(http://rubygems.org/) then download sass on（http://rubygems.org/gems/sass） put in: npm install

Answer 3

The error has something to do with being vulnerable to the Poodle SSL bug, it will not be verified for that reason. If there's a way to upgrade to a better certificate, but at the time of writing this answer, I could not find the upgraded certificate.

I used the non-SSL host instead, altough I should note that this is not the best nor a permanent solution, it lacks security.

The command used:

gem source -a http://rubygems.org/

A discussion about this subject can be found here: https://github.com/rubygems/rubygems/issues/515#issuecomment-65326585

Update: There seems to be a permanent solution now, which replaces the certificate with a proper protected one. It can be found on the following URL, an tutorial is included in that page. https://gist.github.com/luislavena/f064211759ee0f806c88#installing-using-update-packages-new

I also encountered the same problem today。

Running gem install sass returned

ERROR:  Could not find a valid gem 'sass' (>= 0), here is why:Unable to download data from https://rubygems.org/ -SSL_connect returned=1 errno=0 state=SSLv3read server certificate B: certificate verify failed(https://api.rubygems.org/specs.4.8.gz)

Then I find a way to fix it:

1. gem sources -a http://rubygems.org/
2. gem install sass

Adding http://rubygems.org/ to sources solves this.

Here is a capture of my terminal

Changing from http to https makes your computer vulnerable to hackers

I explain some solutions in my answer here: https://stackoverflow.com/a/40075753/845413

If you found this error by searching and are using RVM on OSX just run.

rvm osx-ssl-certs update all

Bundler outlines a few other solutions in their troubleshooting guide for this error: http://bundler.io/v1.16/guides/rubygems_tls_ssl_troubleshooting_guide.html#troubleshooting-certificate-errors

and include...

gem install bundler
gem update --system

Finally, you can simply reinstall RVM or rubygems manually.

Manually install Ruby gems: https://rubygems.org/pages/download

Manually install RVM (recommended): http://rvm.io/

For me it was a proxy issue. When I appended the proxy details to the gem install command it worked.

gem install sass --http-proxy=http://<yourproxy>:<port>
