LoadError: cannot load such file — bcrypt_ext on Windows 2008 x64 server

Question

I upgraded my environment from Ruby 2.0.0 to 2.2.3.

I also upgraded (overwrite) DevKit, and re-run ruby dk.rb install.

I removed Gemfile.lock and ran bundle

Answer 1

Here is the solution worked for me:

    C:\> gem uninstall brcypt
    C:\> gem install --no-ri --no-rdoc bcrypt
    C:\> cd (path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri
    C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> ruby extconf.rb
    C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> make
    C:\(path to gems root)\bcrypt-3.1.7-x86-mingw32\ext\mri> make install
