 If your config contains missing values, you can run the 'init fill-config'
 command to fill in all the defaults, if possible:
 
-python -m spacy init fill-config tmp/starter-config_invalid.cfg --base tmp/starter-config_invalid.cfg
+python -m spacy init fill-config tmp/starter-config_invalid.cfg tmp/starter-config_invalid.cfg
 ```
