Prettier: yarn run prettier throws an error, but directly invoking prettier works

[deepakjois]

Encountered this issue on OS X Sierra, on bash/tmux.

This does not work:

10:17 $ yarn run prettier --write 'src/**/*.js'
yarn run v0.19.1
$ "/Users/deepak/code/personal/moocfetcher-appliance/client/node_modules/.bin/prettier"
Usage: prettier [opts] [filename ...]

Available options:
  --write                  Edit the file in-place. (Beware!)
  --stdin                  Read input from stdin.
  --print-width <int>      Specify the length of line that the printer will wrap on. Defaults to 80.
  --tab-width <int>        Specify the number of spaces per indentation-level. Defaults to 2.
  --single-quote           Use single quotes instead of double.
  --trailing-comma         Print trailing commas wherever possible.
  --bracket-spacing        Put spaces between brackets. Defaults to true.
  --parser <flow|babylon>  Specify which parse to use. Defaults to babylon.
  --color                  Colorize error messages. Defaults to true.
  --version                Print prettier version.

Boolean options can be turned off like this:
  --no-bracket-spacing
  --bracket-spacing=false
error Command failed with exit code 1.

$ ./node_modules/.bin/prettier --write 'src/**/*.js'
src/AppDispatcher.js
src/app.js
src/CopyCourses.js
src/CopyProgressPoller.js
src/CourseItem.js
src/CourseList.js

You need to add in a --:

yarn run prettier -- --write 'src/**/*.js'
