问题
by searching to access my Postgres DB on Openshift, i'm currently facing problem using net-ssh.
- At this step - note that the installed Ruby version is 2.2.0 and net-ssh is 2.9.3-beta1
To be able to access the DB from my local DB IDE, i need to execute:
rhc port-forward myappname
But the execution returns this error: Checking available ports ... Could not parse PKey: no start line
As you can see in this post (an other ones e.g. this one), the fix is to back to a stable version of net-ssh. the 2.9.2. What i've succesfully done.
But now, running rhc port-forward myappname is giving me the following error: .../2.2.0/rubygems/core_ext/kernel_require.rb:54:in 'require': cannot load such file
And the fix is to upgrade net-ssh to the 2.9.3-Beta1 version (see this post).
This is really weird! Seems that "the snake is biting its own tail" (don't know if that french expression got english translation).
Note that i've tried to make a clean setup with new ssh key gen (automatically and manually). My system is runnin' Win 7 64bits.
I made uninstall/install of last version of Ruby. Reinstall of rhc. Last version running on rhc-1.36.4. The problem goes on.
Can you help? Should i install an older version of ssh-net and/or Ruby (i'm not allowed to use ssh-net 2.5.2 due to new version of rhc)?
(sorry for my bad english)
回答1:
You need to use an older version of Ruby, try 1.9.3 or 2.0, or maybe even 2.1.
回答2:
rhc/Gemfile & rhc/rhc.gemspec required gem "net-ssh", "<= 2.9.2"
net-ssh version 2.9.2 use require dl/import atleast on pageant.rb
dl/import is removed from ruby see https://github.com/ruby/ruby/blob/v2_2_0/NEWS#L148-L149
instead fiddle is recommended
net-ssh 3.* seems to fix this(uses fiddle/{import,{ for ruby >= 2.1)
net-ssh version 3. seems to have drop in compatibility(still working on mine) for rhc
So a simple hack is to modify rhc/Gemfile & rhc/rhc.gemspec and install the gem
A guy already have done it.
A Solution(Untested)
gem 'rhc', :git => 'git://github.com/thrasher-redhat/rhc.git'
from https://stackoverflow.com/a/7421712/2382629
Alternative Solution(Tested even on windows 7 32bit :p)
git clone https://github.com/openshift/rhc
cd rhc
modify rhc/Gemfile & rhc/rhc.gemspec like https://github.com/openshift/rhc/pull/748/files then
gem build rhc.gemspec
it should output like
blah! blah! blah! warnings and msgs......
