<Psych::SyntaxError: did not find expected key while parsing a block mapping

Question

When I start the server, I get this error:

I18n::InvalidLocaleData
can not load translations from /Users/Apple/myapp-website-freelance/config/locales/fr.yml: #<Psych::SyntaxError: (/Users/Apple/myapp-website-freelance/config/locales/fr.yml): did not find expected key while parsing a block mapping at line 2 column 3>

Although, the yaml file seems normal at line 2 column 3:

fr:
  Electronics_Circuits_Simulator_Realistic_Interface: "Simulateur de circuits electroniques. Interface reelle."

Any idea?

Answer 1

This error is often misleading and points the wrong line out

Look for extra spaces in the entire YML file and try to replace all enclosing single quotes by "", it should work !

One possible reason is:

default: &default
  a: 1
production: *default
  b: 2

in place of:

default: &default
  a: 1
production:
  <<: *default
  b: 2

Answer 2

Check for any extra whitespace in your YML file. Also, if you were like me you might forgot to remove {} in YML template.
