[node.js] env: node: No such file or directory in mac

I solved it this way:

$ brew uninstall --force node
$ brew uninstall --force npm

after it

$ brew install node

which suggested me to overwrite simlinks

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/doc/node/gdbinit
Target /usr/local/share/doc/node/gdbinit
already exists. You may want to remove it:
  rm '/usr/local/share/doc/node/gdbinit'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

after executing

$ brew link --overwrite node

everything worked again.
