rubygems - Need Help Installing Ruby Gem nio4r

Question

First-time poster and super new to coding. Appologies if I got any of the formatting/structure wrong.

I'm using WSL on Windows 10. This is the error I'm getting when running bundle install

current directory:
/mnt/c/Windows/System32/launch_school/another_book_viewer/vendor/bundle/ruby/2.7.0/gems/nio4r-2.5.4/ext/nio4r
/usr/bin/ruby2.7 -I /usr/lib/ruby/2.7.0 -r ./siteconf20210205-385-1b9hve3.rb extconf.rb
checking for unistd.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

extconf failed, exit code 1

Gem files will remain installed in
/mnt/c/Windows/System32/launch_school/another_book_viewer/vendor/bundle/ruby/2.7.0/gems/nio4r-2.5.4 for inspection.

An error occurred while installing nio4r (2.5.4), and Bundler cannot continue.
Make sure that `gem install nio4r -v '2.5.4' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  puma was resolved to 5.2.0, which depends on<br>
    nio4r

Here are the contents of the mkmf.log file:

"gcc -o conftest -I/usr/include/x86_64-linux-gnu/ruby-2.7.0 -I/usr/include/ruby-2.7.0/ruby/backward -I/usr/include/ruby-2.7.0 -I. -Wdate-time -D_FORTIFY_SOURCE=2   -g -O2 -fdebug-prefix-map=/build/ruby2.7-W7xcA4/ruby2.7-2.7.0=. -fstack-protector-strong -Wformat -Werror=format-security -fPIC conftest.c  -L. -L/usr/lib/x86_64-linux-gnu -L. -Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-z,now -fstack-protector-strong -rdynamic -Wl,-export-dynamic     -lruby-2.7  -lm   -lc"<br>

checked program was:
/* begin */
1: #include "ruby.h"
2: 
3: int main(int argc, char **argv)
4: {
5:   return !!argv[argc];
6: }
/* end */

When I try to run gem install nio4r -v 2.5.4 I get this error:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.7.0 directory.

Is my issue because I don't have permissions to write to the directory? If so, how can I give myself permissions?

Thanks for reading.
