It’s my first time learn rails. Sure I’m a noob in this area. What I did just roamed around looking for guide and stackexchange several time do this and that. Here’s how do I do that.
As I use windows, I downloaded the ruby for windows in rubyinstaller.org. As for the first timer, I just follow the basic: my laptop is 64bit so I need to download and install the 64bit version.
After workaround I thougt I was ready to learn rails. Then I typed
gem install rails
It worked. Then next time I tried was making the blog.
rails new blog
And I doomed. A lot of error showed up. What the…

Some said I had to install bundle. I did instal bundle by `gem install bundle’ and it didn’t work for me. Another Solution came from Vishnu in (stackoverflow)vishnu. He said:
Find your sqlite3 gemspec file. One example is /usr/local/share/gem/specifications/sqlite3-1.3.7.gemspec
You should adjust according with your Rubygem path and sqlite3 version. Edit the file above and look for the following line
change it to
Some people have a good time but some people got sh*t. I’m the second group. There’s a looooot more error showed up.
Then I uninstaled ruby gem from Control Panels on my Windows 10 and delete all the folder related to it.
I started brand new start. I went to rubyinstaller again and read carefully. Then I found (maybe) the source of my problems. The 64bit-version is rather new. So maybe not all the gem, dependencies and anything, tested. Okay then. I’m just have to install 32bit version then.
I installed ruby gems and its devkit without problems.
For safety, I installed bundle before install rails. I got no problem.
I ran rails server
rails new blog
and it works. But it stopped at the middle of
... run bundle
there’s a gem dependency that I couldn’t download. I was not suspiciousing anything. I try again after I install the gem ‘he’ wanted. But got another error with another gem. I think I had problem again here.
Now that RubyGems 1.8.x, 2.0.x and 2.2.x have been released, you can manually update to those versions.
First, download the proper version of RubyGems for your installation (eg.
if running version
Note: To find the version of RubyGems you’re using, please run
gem --version in
the command line.
You can find download links at GitHub under Releases.
X.Y.Z will be the matching
version for the version of RubyGems you need to update:
Please download the file in a directory that you can later point to (eg. the
root of your harddrive
Now, using your Command Prompt:
C:\>gem install --local C:\rubygems-update-1.8.30.gem C:\>update_rubygems --no-ri --no-rdoc
gem --version should report the new update version.
You can now salefy uninstall
C:\>gem uninstall rubygems-update -x Removing update_rubygems Successfully uninstalled rubygems-update-2.2.3
If you have read the above detail that describe the issue, thank you.
Now, you want to manually fix the issue with your installation.
Steps are simple:
If you’ve read the previous sections, you will know what this means (and shame on you if you have not).
We need to download AddTrustExternalCARoot-2048.pem.
Use the above link and place/save this file somewhere you can later find easily (eg. your Desktop).
IMPORTANT: File must have
.pem as extension. Browsers like Chrome will
try to save it as plain text file. Ensure you change the filename to have
.pem in it after you have downloaded it.
In order for us copy this file, we need to know where to put it.
Depending on where you installed Ruby, the directory will be different.
Take for example the default installation of Ruby 2.1.5, placed in
Open a Command Prompt and type in:
C:\>gem which rubygems C:/Ruby21/lib/ruby/2.1.0/rubygems.rb
Now, let’s locate that directory. From within the same window, enter the path part up to the file extension, but using backslashes instead:
This will open a Explorer window inside the directory we indicated.
ssl_certs directory and copy the
.pem file we obtained from
previous step inside.
It will be listed with other files like
There is actually no step 4. You should be able to install Ruby gems without issues now.
I run rails and server by typed
rails new blog2 cd bin rails server
and it works.
Lets learn a lot.Written on October 7th, 2015 by Rudi Adha Prihandoko
