The reason for this error is the security setting on your pc that does not allow you to execute a script.  This is the so-called Execution Policy. By default, the Execution Policy is set to Restricted. This setting means that you may not run any PS1 script at all.

An overview of the policy levels:

Restricted: Individual cmdlets can run, but not saved Powershell scripts. This is the default setting.
AllSigned: Scripts can run, but must have a digital signature even if written on the local computer. Prompts you before running scripts from trusted publishers.
RemoteSigned: Scripts written on the local computer do not need a digital signature, but any script downloaded from outside (email, IM, Internet) must have a signature to execute.
Unrestricted: Any script can run, but scripts downloaded from outside will run with a warning.
