 $ echo . /usr/lib/ckan/default/bin/activate >> ~/.bashrc
 # convenience to default --config value for paster commands
 $ echo export CKAN_INI=/etc/ckan/default/development.ini >> ~/.bashrc

  1. init error

    1. info

       $ vagrant init centos/7
 Vagrant failed to initialize at a very early stage:

 The plugins failed to initialize correctly. This may be due to manual
 modifications made within the Vagrant home directory. Vagrant can
 attempt to automatically correct this issue by running:

   vagrant plugin repair

 If Vagrant was recently updated, this error may be due to incompatible
 versions of dependencies. To fix this problem please remove and re-install
 all plugins. Vagrant can attempt to do this automatically by running:

   vagrant plugin expunge --reinstall

 Error message given during initialization: Unable to resolve dependency: user requested 'vagrant-cachier (> 0)'

    2. not fixed by

       $ vagrant plugin repair
 Repairing currently installed plugins. This may take a few minutes...
 Failed to automatically repair installed Vagrant plugins. To fix this
 problem remove all user installed plugins and reinstall. Vagrant can
 do this for you automatically by running the following command:

   vagrant plugin expunge --reinstall

 Failure message received during repair:

 Vagrant failed to load a configured plugin source. This can be caused
 by a variety of issues including: transient connectivity issues, proxy
 filtering rejecting access to a configured plugin source, or a configured
 plugin source not responding correctly. Please review the error message
 below to help resolve the issue:

   bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)

 Source: http://ruby.taobao.org/

    3. not fixed by

       $ vagrant plugin expunge --reinstall

 This command permanently deletes all currently installed user plugins. It
 should only be used when a repair command is unable to properly fix the
 system.

 Continue? [N]: y

 All user installed plugins have been removed from this Vagrant environment!

 Vagrant will now attempt to reinstall user plugins that were removed.

    4. fixed by

       $ brew cask uninstall vagrant
 $ brew cask install vagrant

  2. This is usually because the filesystem “vboxsf” is not available

    1. info

       $ vagrant up
 ...
 Vagrant was unable to mount VirtualBox shared folders. This is usually
 because the filesystem "vboxsf" is not available. This filesystem is
 made available via the VirtualBox Guest Additions and kernel module.
 Please verify that these guest additions are properly installed in the
 guest. This is not a bug in Vagrant and is usually caused by a faulty
 Vagrant box. For context, the command attempted was:

 mount -t vboxsf -o uid=1000,gid=1000 etc_ckan_default /etc/ckan/default

 The error output from the command was:

 mount: unknown filesystem type 'vboxsf'

    2. fixed by install vagrant-vbguest

       $ vagrant plugin install vagrant-vbguest
