Installation fails in CircleCI

[Gabriel Rubens Abreu]

Thanks for the great package.
I'm tried to setup a CD in CircleCI and I'm always getting this:

Arguments: -c if [ ! -f ./ppx ]; then ln -s "$(opam config var graphql_ppx:bin)/graphql_ppx.native" ./ppx && chmod +x ppx; fi
Directory: /home/circleci/repo/node_modules/graphql_ppx
Output:
chmod: cannot operate on dangling symlink ‘ppx’

this is my .circleci.yml
