Wy I can't find a right guide to install redmine on centos7.0?
It's Very Very Pity,
So far, I haven't find a right guide to install redmine on centos 7?
But it failed in "gem install passenger" ,the error as:
[root@localhost redmine-3.3.0]# gem install passenger ERROR: Error installing passenger: rack requires Ruby version >= 2.2.2.
2. While I use other guide, the guide tells me to use ruby of v1.9? When I use to install rails, the error tell me to install ruby above 2.0 version.....
3. While, I use the update the ruby version to 2.2, there is another question occured: #25224
So, How can I do??????????????????
