I had a bunch of weird errors, like actionpack requires a certain version of rack, etc. when trying to use the gem install rails and other such commands.<\/p>\n

I found it easier to remove any gems that were old, and then just download each gem dependency from rubyforge.org. Then I could download each gem, go to that download folder in the command line, and run sudo gem install GEMNAME <\/em>– -local, and make sure the versions I wanted for everything were correct<\/p>\n

ruby extconf.rb install mysql
\nextconf.rb:1:in `require’: no such file to load — mkmf (LoadError)
\n from extconf.rb:1<\/p>\n

Make sure the package rubyXX-dev is installed. This will stop the mkmf errors.<\/p>\n

ruby extconf.rb install mysql
\nextconf.rb:1:in `require’: no such file to load — mkmf (LoadError)
\n from extconf.rb:1<\/p>\n

When installing the mysql gem in ubuntu make sure you have the following 3 packages installed: build-essential, rubyXX-dev, and libmysqlclientXX-dev, where the XXs correspond to your version numbers. <\/p>\n

If you want to read the log, in ubuntu 9.10 with ruby 1.8.7 and rails 2.3.4 it was in \/var\/lib\/gems\/1.8\/gems\/mysql-2.8.1\/ext\/mysql_api\/mkmf.log<\/p>\n

Also be aware that 9.10 ubuntu’s default mysql sock appears to be \/var\/run\/mysqld\/mysqld.sock<\/p>\n","protected":false},"excerpt":{"rendered":"
