Gem documentation is installed in [RUBY]/lib/ruby/gems/doc, where [RUBY] is the directory into which you installed Ruby (C:/ruby on my machine).

I don't see why you shouldn't just delete the folders representing the gems for which don't don't need documentation: you can always regenerate it.

I understand there is a .gemrc file that may be used.

puts the two lines in it.
I believe you put the .gemrc file in your $Home directory.

I can't answer the first part of your problem (I have the same issue myself) but I have managed to not install documentation by default.

You can specify some default command line options in the <a href="http://docs.rubygems.org/read/chapter/11" rel="nofollow noreferrer">gem config file</a>, you can specify not to generate documentation (something like --no-rdoc and --no-ri).

This command worked for me in removing documentation installed by install.

<pre><code>rm -r "$(gem env gemdir)"/doc/*
</code></pre>

Here's another way to go about it;

To locate the folder where gems are installed on your system, simply run the following on terminal or shell

<pre><code>gem env home
</code></pre>

This will display an output like

<pre><code>/home/username/.rbenv/versions/2.5.5/lib/ruby/gems/2.5.0
</code></pre>

You can then locate the docs folder and delete all the documentations that you find there for each gem in a ruby version

I also want to add this too to the answers provided, 

if want to prevent gems from generating documentation during installation, then turn off local documentation generation by creating a file called ~/.gemrc which contains a configuration setting to turn off this feature:

Simply run this code in your terminal or shell 

<pre><code>printf "install: --no-rdoc --no-ri\nupdate: --no-rdoc --no-ri\n" &gt;&gt; ~/.gemrc
</code></pre>

OR

<pre><code>echo "gem: --no-document" &gt; ~/.gemrc
</code></pre>

This will prevent gems from generating documentation during installation, saving you the stress of deleting/removing gem documentations on your system later.

That's all

I hope this helps.

I know it's possible to install a gem without the documentation, but unfortunately, I didn't for the first three months I used ruby. In that time, I managed to install a significant amount of gems, but not once since I started using ruby have I used the documentation on my computer. I always look to docs on the internet.

What is the best way to safely remove the documentation from my computer? Also, is there a way to configure ruby to not install documentation by default?

How do you remove the documentation installed by gem install?

我知道可以在没有文档的情况下安装gem，但不幸的是，我在使用ruby的前三个月没有这样做。在那段时间里，我成功地安装了大量的gem，但自从我开始使用ruby以来，我一次也没有在我的电脑上使用过文档。我总是在网上找医生。从我的计算机中安全删除文档的最佳方法是什么？另外，有没有办法将ruby配置为默认不安装文档？
