Jammit installation issue (no such file to load — win32/open3 (LoadError)) in Windows
Installed jammit gem.
gem install jammit
Added to gem file.
Started my server and got error no such file to load — win32/open3 (LoadError)
Then I installed the win32-open3 gem.
gem install win32-open3
Again started the server got the same error and then I added it in gemfile.
Things started working properly.
