Leaving this gist in the hopes that this helps someone some day.

I was using a docker image with Alpine linux. In this docker container I installed a specific version of node via several methods (nodenv, asdf, etc.) and each time I had to add the gcompat package so I could run glibc applications.

When I tried to install many npm packages such as yarn and corejs and others I would get the error:

Error: spawn sh ENOENT

I belive I finally realized that Error: spawn sh ENOENT is happening since npm is trying to launch sh and there is some incompatibility with a glibc app running with gcompat trying to launch a non-glibc app like sh

For the numbers 1 through 1000

• if the number is divisible by 5 print Iron

• if the number is divisible by 7, print Yard

• if it is divisible by both 5 and 7, print IronYard

• that is:

1

First step is to install the correct version of the Ruby environment:

rvm install ruby-2.4.2
