I try to migrate Redmine 0.9.1 to 3.4.2 and one migration plugin failed. The plugins is question

My plugins migration failed with this command.

I want to install Redmine on my Raspberry Pi2. When I tried to run the command sudo bundle install --without development test rmagic I got this as output:

And when I wanted to run gem install rake -v '12.0.0' or gem install i18n -v '0.7.0' the command did not started and I got only > symbol on the start of the row, like when I want to edit something on mySQL through CLI.

What I missed? I didn't found this in the Documentation. I installed followed by these steps.
