Calling grunt fails on linux server

While trying to run grunt on a new machine using a file that I have seen work before I get this error:

```
grunt[41447]: ../src/node_contextify.cc:676:static void node::contextify::ContextifyScript::New(const v8::FunctionCallbackInfo&): Assertion `args[1]->IsString()' failed.
1: 0xa04200 node::Abort() [grunt]
2: 0xa0427e [grunt]
3: 0x9f5b93 node::contextify::ContextifyScript::New(v8::FunctionCallbackInfo const&) [grunt]

7: 0x1401319 [grunt]
Aborted (core dumped)
```

This is similar to #1660, but since I have never had any prior version of node or npm on this server, I'm at a lost to how to fix this. If a lower version of node, or a specific version of natives is required, it would be nice to have this in the documentation.

Node: 14.15.5 (also failed on 10.19.0)
Npm: 6.14.11

Start by reproducing the failure with the reported Node 14.15.5 and 10.19.0 versions, then compare the symptoms and troubleshooting context in issue #1660. Determine whether the failure is a compatibility or documentation problem; done means the required Node, npm, or natives versions and a reliable workaround are documented.
