`"postinstall": "opencollective || exit 0"` reportedly fails in PowerShell

[hedgerh]

I wanted to pass this along from an issue in nestjs: nestjs/nest#7049

The setup provides this postinstall script:

"scripts": {
  "postinstall": "opencollective || exit 0"
},

According to the reporter of this issue above, that script fails on PowerShell, throwing this error:

> opencollective || exit 0

At line:1 char:16
+ opencollective || exit 0
+                ~~
The token '||' is not a valid statement separator in this version.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : InvalidEndOfLine

Because || isn't a valid operator in PowerShell. It uses something like -or/-and instead of ||/&&. As a result, they aren't able to install a project that uses nestjs v7.

I'm not sure why the || exit 0 is required, but I wonder if there's a cross-platform alternative that would work for PowerShell.
