see https://github.com/jamiew/git-friendly for more ideas
|
|
|
|
maybe this should be two files
|
|
one which includes cloning diaspora/diaspora, and one that assumes you already cloned it yourself
|
|
maybe one script just calls another?
|
|
|
|
|
|
other ideas what we could do
|
|
|
|
1. check that you have ruby installed, if not, point to wiki page and exit
|
|
2. check to see if we need sudo (generally, if it is a system ruby you need sudo, which you can check
|
|
if which ruby is /usr/bin/ruby, or does not have rvm in the path)
|
|
3. check if you have bundle installed and install it, and install with/without sudo if you need it
|
|
|
|
check if you have mysql and/or postgres installed, point to wiki page if neither is found.
|
|
(maybe even switch database.yml if this is the case?)
|
|
|
|
make it work if you have just cloned diapsora and want a quick setup, or
|
|
support magic install, like this http://docs.meteor.com/#quickstart

RVM was not found on your system (or it isn't working properly).

It is higly recommended to use it, since it's making it extremely easy

It worked! :)

Now, you should have a look at
|
|
|
|
- config/database.yml and
|
|
- config/application.yml
|
|
|
|
and change them to your liking. Then you should be able to
|
|
start Diaspora* in development mode with:
|
|
|
|
`rails s`
|
