I did go through the suggesstions in following posts [תמונה] Plugin using own gem Development Gems declared in a plugin are installed and loaded differently as per our implementation: In order to get it to work, you’ll have to specify all the gem’s dependencies which are not already included in the Gemfile.

I don’t know, but you might make sure that the directory that is getting to write to is world writable.

I can run the plugin locally… But in the server, the docker rebuild causes this issue. Are you suggesting that I should enter inside docker, and change the permissions of folder to writable? I will try that out, but if it would have been possible from plugin itself, it would be great.

This is not how you include gems, [תמונה] Plugin with custom gems Development Add your gem dependencies (all the dependency tree) to your plugin.rb file: The version has to be specific, you can not use ~>

Apparently, the most salient part of my earlier message was “I don’t know”. :slight_smile:

Hi @sam, thanks for answer. I tried this many times in different configurations, but it failed. Then I came to know real cause, though I do not know the solution When I install the discourse-backups-to-dropbox plugin from github (plugin that you shared), the docker builds properly. But if I put it discourse-backups-to-dropbox in private repository like bitbucket, it throws the error. The error logs for the plugin are same as shared in first post ie E -u discourse bundle exec rake db:migrate ERROR: While executing gem … (Errno::EACCES) Permission denied @ dir_s_mkdir - /var/www/discourse/plugins/discourse-backups-to-dropbox/gems I, [2017-07-10T18:18:41.229582 #15] INFO – : /root is not writable. Bundler will use `/tmp/bundler/home/discourse’ as your home directory temporarily. gem install public_suffix -v 2.0.5 -i /var/www/discourse/plugins/discourse-backups-to-dropbox/gems/2.4.1 --no-document --ignore-dependencies You are specifying the gem public_suffix in /var/www/discourse/plugins/discourse-backups-to-dropbox/plugin.rb, however it does not exist! I, [2017-07-10T18:18:41.230126 #15] INFO – : Terminating async processes So I guess the problem lies in the my private repo configuration. But if the plugin(without any gem) gets installed properly from bitbucket, I do not know why would installing plugin with gem throw error. It should not matter whether the plugin is in open repository like github or in private repo like bitbucket. My private repo config exec: cd /var/www/discourse && sudo -u discourse bundle install --deployment --without test --without development exec: mkdir /root/.ssh exec: ssh-keyscan -t rsa bitbucket.org > /root/.ssh/known_hosts exec: echo “Host bitbucket\n\tStrictHostKeyChecking no\n\tHostName bitbucket.com\n\tIdentityFile /root/.ssh/id_rsa\n” >> /root/.ssh/config file: path: /root/.ssh/id_rsa chmod: 600 contents: | -----BEGIN RSA PRIVATE KEY----- … … -----END RSA PRIVATE KEY----- file: path: /root/.ssh/id_rsa.pub chmod: 600 contents: ssh-rsa … exec: cd $home/plugins && git clone git@bitbucket.org:path/to/discourse-backups-to-dropbox.git exec: cd $home && sudo -E -u discourse bundle exec rake db:migrate exec: cd $home && rm -fr tmp/cache exec: cd $home && sudo -E -u discourse bundle exec rake assets:precompile exec: rm /root/.ssh/id_rsa exec: rm /root/.ssh/id_rsa.pub Its same as mentioned in tutorial https://meta.discourse.org/t/install-a-plugin/19157/33?u=net_deamon

You are awesome @pfaffman. Thanks :slight_smile: :+1:

[תמונה] pfaffman: chmod - r 777 That is one hell of a scary advice. I advise to figure out which user needs write permissions, and then chown it to that user, keeping the permissions at 0755.

Thanks :slight_smile: , Yes I am now rebuilding with 755. Atleast I got to know where the issue was. I had been struggling with this for 3 days …

Yes. Once you see if that fixes it and what the ownership of the files created are, you should take steps to lock things back down.

I still don’t know.

If sounds like a permissions problem. You might chmod - r 777 the repo after you clone it.
