+**nvm node version not found in vim shell**
+
+If you set node version to a version other than your system node version `nvm use 6.2.1` and open vim and run `:!node -v` you should see `v6.2.1` if you see your system version `v0.12.7`. You need to run:
+
+```shell
+sudo chmod ugo-x /usr/libexec/path_helper
+```
