Hi, I try to install discourse v1.7.0.beta10 version.

There are some reason that I can’t use docker which discourse offer.  
so I try to install from source directly.

I have base ubuntu which installed discourse v1.6.4 before and I reuse this one.  
But I get this error when I try to db migrate.

`TypeError: no implicit conversion of nil into String`

I guess it is because of ruby or postgres version.  
On my ubuntu, I use

```plaintext
ruby : 2.3.0
postgres: 9.4

```

Is there any specific version do I have to use?

Even when not using the supported install, you should [take a look at it](https://github.com/discourse/discourse_docker/blob/master/image/base/Dockerfile) to see what it uses.

We are using PostgreSQL 9.5 currently.

You might try starting with the development environment install instructions and then try to switch to production mode.
