New versions of node break the build

[grandafrato]

When I tried building with node js 1.14+ i got this error:

/tmp/codon/tmp/buildpacks/046a7dbb0bd21772e3b9d262d0fbe72be102671d/lib/build.sh: line 29: fail_bin_install: command not found

And the whole deployment would fail. However, when I used version 10.20.1 (because that's the version used in the phoenix docs) it just suddenly did work. I did not test for any versions in between that one and 1.14.0

I also had a problem with a newer Node version (12.15.0):

Same problem here with a deployment using Heroku. npm 6.14.13 and yarn 1.22.11

Edit : The version of node was wrong. The error was solved by adding this to phoenix_static_buildpack.config :

node_version=14.17.3
npm_version=6.14.13
yarn_version=1.22.11
