spring = 1.7.2 on Mac Sierra & Ruby 2.3.3 #6
Description
Received the following error using spring = 1.7.2
'You have requested:
spring = 1.7.2
The bundle currently has spring locked at 2.0.1.
Try running 'bundle update spring'
If you are updating multiple gems in your Gemfile at once,
try passing them all to 'bundle update''
I used 2.0.1 for the tutorial and it worked out fine.
