C:\RubyDevKit>gem install jekyll ERROR: Could not find a valid gem 'jekyll' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/latest_specs.4.8.gz)

Any Ideas?

[EnterpriseWide]

I just found this and it worked so this may be worth putting in your doco.

$ gem sources --remove https://rubygems.org/ $ gem sources -a http://rubygems.org/ $ gem install jekyll

I found this info here - https://github.com/jekyll/jekyll/issues/1409

@EnterpriseWide This problem (and fix) is desribed here: https://gist.github.com/luislavena/f064211759ee0f806c88 I agree, it could be included in the guide.

@EnterpriseWide in step 2 can you help me ?

[EnterpriseWide]

Hi there, When I did this, the installer was very fussy about the url used. When I run gem sources , I get http://rubygems.org/. I think you may have to put the forward slash on the end.

Regards

Hi,

just went here to file this issue. I just had the same error. Installing any gem failed due to some certificate validation issues. I found the solution by myself on the web, but took some time, so I think it would be really useful to include some note about this on the guide.

I simply removed the SSL source and added the plain HTTP one

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

I used ruby 2.0 x64 on a Windows 8.1 machine.

Thx

I just ran into the same issue on Ruby 2.1 x64 + Windows 8.1, and found another solution: https://stackoverflow.com/questions/5720484/how-to-solve-certificate-verify-failed-on-windows/16134586#16134586 .

[bst27]

I hade the same issue and solved it by creating a gemrc file (workaround 3) like described there: http://railsapps.github.io/openssl-certificate-verify-failed.html

[dmcglinn]

The solution suggested by @juristr worked for me, thanks!

[tnbuig]

Thanks @juristr its help for me as well

[DONGChuan]

Thanks to @juristr. It works well. But It's better to fix this issue in beloved jekyll itself

[MohammedRabaya]

I just tried installing the latest version of gem manually and it worked!

[joeywen]

Thanks to @EnterpriseWide . It works well

[josekenya]

I encountered the same issue.The fix is here https://gist.github.com/luislavena/f064211759ee0f806c88 Thx Everyone.

Just upgrade to the latest rubygems available and it should fix the issue. Specifically, 2.2.3, 2.0.15, 1.8.30 have this fix backported. Note that on Windows 2.4.x might have other issues so in that case switch to 2.3.0.

For Chinese user blocked by the Great Wall , you can refer ruby.taobao.com do this:

$ gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/

[WhaleChen]

@EnterpriseWide @juristr 3x。 It really works！ @wenzhishen Great Wall Oh! 3x!

[zdawei]

@EnterpriseWide thank you .

[JashonWang]

@juristr Your suggestion worked for me! Thanks very muck.

[jeffersondesouza]

@juristr suggestion worked to me, I'm using windows 7

[MukunziChild]

Thanks man, you saved my ass from a lot of pain. I've been dealing with this for months every time I installed a new gem in my rails projects.

Thanks Ben @EnterpriseWide

@juristr your suggestion works for me, i'm using windows 10, thank you

[Donatoni-zz]

This worked for me and I got the guide off of Jekyll's install page. So I'm pretty confident this will work for anyone having the same issue.

http://guides.rubygems.org/ssl-certificate-update/

[costanzo]

@EnterpriseWide you solution is perfect!

[SalN3t]

Make sure you have all the packages

sudo apt-get update
sudo apt-get install ruby ruby-dev make gcc 

If you do then remove ruby first

sudo apt-get remove ruby

Then run the ones above.

Then do the commands @EnterpriseWide shared above

gem sources --remove https://rubygems.org/
gem sources -a http://rubygems.org/
sudo gem install jekyll

What @juristr said fixed my gem install problem on macOS Sierra 10.12.6 (16G29)

[ashirafzal]

juristr you boii you have fixed my problem on windows 7 thnx for it buddy ! @juristr . Many many thx

请尽可能用比较新的 RubyGems 版本，建议 2.6.x 以上。

$ gem update --system # 这里请翻墙一下 $ gem -v 2.6.3 $ gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/ $ gem sources -l https://gems.ruby-china.com

确保只有 gems.ruby-china.com 2020年3月31日 14:11:03

如果遇到 SSL 证书问题，你又无法解决，请修改 ~/.gemrc 文件，增加 ssl_verify_mode: 0 配置，以便于 RubyGems 可以忽略 SSL 证书错误。
