npm-link-permission-denied-after-build-babel.sh

# During development of a node module (CLI) using babel to transpile ES6 code i ran in to the following problem

# EXAMPLE my-awsome-module
npm link
my-awsome-module # => Works as expected

# do some changes to my-awsome-module
# ...babel transpiles code
my-awsome-module # => zsh: permission denied: my-awsome-module

# SOLUTION
# give permissions to execute executable source files
chmod +x /src/bin/index.js
