I’m trying to automate a ruby app deployment on a Windows machine with a batch script.

Everything is going dandy, except for the following line: 

gem install bundler

If I type this in manually, all goes well. If I use a batch script, however, the process is killed as soon as the installation completes. This is what I’m using: 

pause
gem install bundler --no-ri --no-rdoc
pause

I’ve tried with the -f switch and also all docs; nothing seems to prevent the window from getting killed. I need the process to stay alive so I can bundle install. Any idea why this is happening, and how I can keep it alive post-install?

    gem is a batch file (gem.bat). When you’re invoking a batch file from another one, it is transferring control to it and not resuming.

    You should try using CALL instead:

    CALL a second batch file
    The CALL command will launch a new batch file context along with any specified arguments.
    When the end of the second batch file is reached (or if EXIT is used), control will return
    to just after the initial CALL statement.

    Documentation here:
    http://ss64.com/nt/call.html

    You can also avoid the batch file by doing ruby -S gem ... which is more verbose and will work since there is a gem (extensionless) file along gem.bat.

    Hope that helps.
