bundle exec ...の次はインデント2つにしないとダメ
deployment: production: branch: master commands: - bundle exec cap production deploy: timeout: 1500
Note that YAML is very strict about indentation each time you add a new property. For that reason, modifiers must be indented one level from their command. In the following example, we treat the bundle install command as a key, with timeout, environment, and pwd as the command's hash values.
