问题
When I try using rake db:migrate I get this error:
LoadError: cannot load such file -- tiny_tds/tiny_tds
D:/myrailsapp/config/application.rb:7:in `<top (required)>'
D:/myrailsapp/Rakefile:4:in `require_relative'
D:/myrailsapp/Rakefile:4:in `<top (required)>'
LoadError: 126: The specified module could not be found. - D:/RailsInstaller/Ruby2.2.0/lib/ruby/gems/2.2.0/gems/tiny_tds-1.1.0-x86-mingw32/lib/tiny_tds/2.2/tiny_tds.so
D:/myrailsapp/config/application.rb:7:in `<top (required)>'
D:/myrailsapp/Rakefile:4:in `require_relative'

(See full trace by running task with --trace)
This is my database.yml file:
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
#
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
development:
adapter: sqlserver
mode: odbc
dsn: railsapp
database: sqlserverapp
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
database: db/production.sqlite3
Can somebody help? I can't seem to find a solution, I've looked basically everywhere on the web and can't find a proper solution to this specific case, I've tried uninstalling and reinstalling, and both gems are declared on gemfile.
回答1:
I ran into this problem recently, and it turns out that the issue was due to the Ruby DevKit not being included in my Windows system and user PATH variables.
