Error when starting the Rails server on Windows

Question

Right after launching rails server command Ruby terminal doesn't start the server and writes following:

When looking for answers to similar question, I haven't found any working solution. I can say that:

1. Application is created in directory, in which path are only English symbols.
2. I tried to fix problem using: gem cleanup bundle install
3. I tried to start the server using: bundle exec rails server .
4. I tried to delete the gems which contain "problem" in the gemfile.
5. Also tried to fully reuninstall Ruby and Rails with all gems.

All that didn't help, so I would really appreciate for working in my case solution!

PS I am working on: Windows 8.1 (64-bit), Ruby 2.3.0, Rails 5.0.0

Answer 1

Find your sqlite3 gemspec file. One example is

`/usr/local/share`/gem/specifications/sqlite3-1.3.7.gemspec`

Windows: C:\\Ruby21\\lib\\ruby\\gems\\2.1.0\\specifications.

You should adjust according with your Rubygem path and sqlite3 version. Edit the file above and look for the following line

s.require_paths=["lib"]

change it to

s.require_paths= ["lib/sqlite3_native"]

Hope that helps!!!
