Keep Getting NoMethodError when trying to install Plugins

Added by Neal Bharadwaj about 10 years ago

I am able to get the plugins to show up under the plugin list. Some, like the screenshot capture, and new issue alert work fine.

When installing the charts plugin and the Require Closing note I keep getting a similar error.

Redmine 0.9.6
mysql 5.1.48
php 5.3.2
Ruby 1.8.7
Apache 2.2
Gem List

actionmailer (2.3.5)
actionpack (2.3.5)
activerecord (2.3.5)
activeresource (2.3.5)
activesupport (2.3.5)
cgi_multipart_eof_fix (2.5.0)
gem_plugin (0.2.3)
mongrel (1.1.5 x86-mingw32)
mongrel_service (0.3.4 i386-mswin32)
mysql (2.8.1 x86-mingw32)
rack (1.0.1)
rails (2.3.5)
rake (0.8.7)
win32-service (0.5.2 mswin32)

I followed this tutorial to set it up on the computer I am working on.

Your help is appreciated.

RE: Keep Getting NoMethodError when trying to install Plugins - Added by Felix Schäfer about 10 years ago

Those are version mismatches, or at least for the charts plugin. The charts plugin tries to call a method that is present in trunk redmine, but not in 0.9.6.

RE: Keep Getting NoMethodError when trying to install Plugins - Added by Neal Bharadwaj about 10 years ago

I used Yuja's version of Charts which is supposed to have the fix to make it work with 0.9.6

RE: Keep Getting NoMethodError when trying to install Plugins - Added by Maciej Szczytowski about 10 years ago

The issue has been fixed in the latest version of plugin.

I tried your fork with redmine 1.01, but have the same problem (error 500) as with the original plugin
