I have downloaded yarn yarn-1.7.0-1.noarch.rpm

when I run `sudo rpm --install yarn-1.7.0-1.noarch.rpm` I get the following error

```
error: Failed dependencies:
        nodejs is needed by yarn-1.7.0-1.noarch

```

If I run `node -v`

I get `v8.9.4`

I know node is installed anyway because we are already using it on this server for many microservices.

I am unable to use npm because I am behind a proxy and npm is now unusable with error 418 I am teapot
