Installing bundler
You need to install Bundler globally, not only for the current project (in the project directory). This is because Bundler provides a consistent environment for Ruby projects by tracking and installing the exact gems and versions that are needed.
Open a terminal and write
gem install bundler
You can check if the installation is successful by writing
bundle -v
