When I attempt to run rake assets:precompile I am having a weird issue that appears to be related to my database.yml. However, accessing the website directly works fine (if i change the environment to fall back on the asset pipeline).<\/p>\n

Rails 3.2.12, ruby 1.9.3p385, Windows Server 2008.<\/p>\n

My database.yml file (host, username, and password removed):<\/p>\n

\nproduction:\n  adapter: mysql2\n  encoding: utf8\n  reconnect: true\n  database: images\n  pool: 5\n  username: username\n  password: password\n  host: host\n<\/pre>\n
A snippet of the top portion of the error:<\/p>\n

Here is the contents of connection_specification.rb, it bombs out on this line: :database => config.path.sub(%r{^\/},\"\"),<\/code>:<\/p>\n

    Your output generates this: RAILS_ENV=assets:precompile<\/p>\n
    however I do not think you’ve declared an assets environment.<\/p>\n
    try $:. rake assets:precompile RAILS_ENV='production' RAILS_GROUPS='assets'<\/code><\/p>\n
    PS: windows is.. let’s say undeveloped when it comes to rails support so you may want to think about switching to another OS. My personal favorite is Debian sqeeze<\/p>\n<\/li>\n<\/ol>\n
