Hi, could someone tell me how to list and update the currently

Thanks in advance,

If you’ll run gem\_server and then point you browser to  
[http://localhost:8808](http://localhost:8808) you’ll see a list of your installed gems.

I use

c:\>gem list

to see the list. I believe

c:\>gem update --include-dependencies

will update all your gems and all of their dependencies. I usually  
update one gem at a time, for example:

c:\>gem update rake --include-dependencies

but according to the help (gem update --help) it seems to imply that all  
gems will be updated if you don’t specify a particular gem.

Conrad-

```
This command will list all your currently installed gems:

```

$ gem list

```
And this one will list all the gems available from rubyforge:

```

$ gem list --remote

```
And to update all your installed gems:

```

$ sudo gem update

```
Also this is your friend:

```

$ gem help
