Answer 1

Try removing ~/.bundle/cache/. That fixed this issue for me.

On Windows: Try to reinstall rubyinstaller-devkit.

Answer 3

How do I install sqlite3 for Ruby on Windows?

it was here my solution !

You can also download ruby on rails with devkit https://github.com/oneclick/rubyinstaller2/releases/download/RubyInstaller-2.6.3-1/rubyinstaller-devkit-2.6.3-1-x64.exe

Even though the question has been answered, I want to post my research to help others. I found a lot of information online, but being a Ruby newbie I had a tough time following all. The basic answer comes from the following post https://github.com/luislavena/sqlite3-ruby/issues/82 with instructions by "paulwis" on how to properly install sqlite3 for ruby 2.0.0-p0 and some comments on https://github.com/rails/rails/issues/10150 . So here it is:

1. Install the Ruby Devkit for your setup (DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe for me since I use a x64 machine)
2. Download and extract the autoconf package from Sqlite.org
3. Run msys.bat (it is inside the ruby devkit root folder)
4. cd into the path where you downloaded the sqlite source (for example: "cd /c/dev/sqlite3" for path "c:\dev\sqlite3" if you are new to MSYS/MINGW32)
5. "./configure"
6. Run "make"
7. Run "make install"

8. Get the sqlite3 gem again, this time specifying the platform and the path to the newly compiled binaries:

   gem install sqlite3 --platform=ruby -- --with-sqlite3-include=[path\to\sqlite3.h] --with-sqlite3-lib=[path\to\sqlite3.o]
   

For example:

gem install sqlite3 --platform=ruby -- --with-sqlite3-include=/c:/dev/sqlite3/ --with-sqlite3-lib=/c:/dev/sqlite3/.libs/

(from the paths given in step 4)

Check the Gemfile.lock of your rails app and make sure that it points to the correct sqlite3 version. Mine was "sqlite3 (1.3.7-x86-mingw32)" and manually changed it to "sqlite3 (1.3.7-x64-mingw32)". Removing the platform also works: "sqlite3 (1.3.7)".
