Does ri know about all ruby classes?
题
When I pass CSV
to ri
I get this output
Nothing known about CSV
I thought all ruby classes are documented with ri.
解决方案
CSV is a part of standard library and is fully documented. That issue may be linked wit rvm using. Try to prepare rvm docs generate
command.
其他提示
If RI returns "NOTHING KNOWN ABOUT..." the documentation may be missing.
RI documentation isn't included when Ruby is installed. It must be manually generated - ideally, immediately after installing EACH VERSION of Ruby (before the downloaded installation files are cleaned up).
To generate it:
$ rvm docs generate
If that doesn't work, check this RVM.io page for command options & scenarios.
