Symfony2 - generate:bundle command throws Notice: Undefined variable: output

Question

I'm new to Symfony2 framework and following an online tut. However, when I reached the point to setting up a bundle in CMD following message repeatedly appearing.

Configuration format (annotation, yaml, xml, php) [annotation]: Notice: Undefined variable: output

Does anyone encontered similar problem? (see the screen shot)

Answer 1

This error appears because you disabled exec and/or shell_exec in your php.ini . To debug run one of the following commands:

# linux/osx
php -i | grep 'disable_functions'
# windows
php -i | findstr 'disable_functions'

If the disable_functions ini-directive contains exec or shell_exec ...

disable_functions=exec,passthru,shell_exec,system,proc_open

... remove them from disable_functions in your CLI's php.ini as suggested in this answer .
