Can't install in Redmine 2.6 - cannot specify same gem twice

[yozart]

While executing the migrate command, I got the below error message.

You cannot specify the same gem twice with different version requirements.
You specified: mysql2 (=0.3.11) and mysql2 (~) 0.3.11)

I used the latest version available (from 4 days ago). My redmine is bitnami redmine 2.6

you could comment out the line in plugins/redmine_didyoumean/Gemfile

This results in the following when installing on Redmine 2.6.1 on Windows without Sphinx.

type bundle install

[yozart]

Well, I have some proxy issues for the time being. I can't do any bundle install ! If anyone managed to get it working behind a firewall, I'd be glad to get some help. I saw dozens of topics on this subject but none of them helped. I guess issue is coming from the proxy

[dominch]

I'm behind firewall too, and it's not working without setting system variables:

export http_proxy=http://proxy01.company.net:3128
export https_proxy=http://proxy01.company.net:3128

That works for bash + linux, You may have different settings and different proxy access control.

[yozart]

Hello thanks for the answer but already tried it. Unfortunately didn't worked for me. I also tried to define those in Environment settings (I'm on Windows Server using Bitnami installer).

As I said, I guess it's more related to some configuration issues on the proxy or firewall. I need to see with my network team. Thanks anyway. I'll tell you up to date once I got a solution

[rlisowski]

I see few solutions for proxy problems

1. you can set it in ~/.gemrc (I think ~ is $HOME) eg:
   `

   install: --http-proxy=http://USERNAME:PASSWORD@ADDRESS:PORT
   `
   see rubygems command reference
2. set transparent socks proxy, I never tried it on windows
3. use proxy wrapper eg. proxychains or proxytunnel
4. package gems on other platform, copy to windows and instal with --local flag

FYI environment can be set in Gemfile, on top of the file write ENV['http_proxy'] = 'user:pass@proxy:port'

[yozart]

Thanks for those information. I finally went with solution "Package gems on another platform and install them using --local flag
I was failing to set proxy configuration and Proxy team was not very cooperative to help ;)
