Rails需要RubyGems> = 1.3.2。 请安装RubyGems，然后重试（我有rubygems 1.3.6！）

Question

I'm running rails version 2.3.5 and rubygems version 1.3.6, when I script/server I get this error

Rails requires RubyGems >= 1.3.2. Please install RubyGems and try again: http://rubygems.rubyforge.org

any ideas how to fix this?

Answer 1

The first thing you should do is run: gem env

This will output, amongst other things, the RUBYGEMS_VERSION and your GEM_PATHS. Verify that everything you think is true, is indeed true.

In the GEM_PATHS, you will probably see multiple paths, the top most being the primary path.

You can set GEM_HOME to the primary gem directory in the your .bash_login/etc file. Open a new terminal and run gem env again to make sure that it is being picked up.

As Gordon indicated, make sure these GEM paths are in your PATH.

Some other things to think about ownership/permissions. If you use sudo when working with gems on your system, they get installed in a different directory than when you install/update normally.

Perhaps you installed the rubygems using sudo, but rails is not running as root.

Read the installation notes if you still cannot figure it out: ruby gems installation

Answer 2

Maybe it's not finding your correct gem path. I've had similar problems related to that. You might need to update your bash prefs eg in .basrc you might have something like this:

GEMS=/home/me/ruby1.8/lib/ruby/gems/1.8/bin/ export PATH=$RUBY:$GEMS:$HOME/bin:$PATH:$NGINX:$MONIT:$GIT

Answer 3

I just ran into this issue today, and for those of you who do something similar to what I did here is the fix and a little background.

I was installing some dependencies for rmagik, took the easy way out and used macports, it automatically went ahead and updated my default ruby to /opt/... so rubygems went missing since it only intalled ruby.

my advise, use rvm (http://rvm.beginrescueend.com/) like raphael_turtle says, since you will want RVM to be in charge of updating your links to ruby, rubygems and rails.

*Be wary when installing via macports or brew, just make sure you see what else is being installed, and don't accidently overwrite your local configs.

Answer 4

I had the same problem. My installation was done for me by technical support, so it was not me who did the installation (security problems).

The problem was that I didn't have some access rights, so this helped:

sudo - su user_name_with_enough_access_rights

And then run scripts/server again.

Answer 5

我不知道出了什么问题，所以我在rvm上安装了新版本的rails和ruby。
