Does not work in Node 10 (Assertion `args[1]->IsString()' failed)

[Nickersoft]

Expected behaviour

karma start should execute tests as expected.

Actual behaviour

Running karma start results in the following error, a known issue in Node 10:

node[9155]: ../src/node_contextify.cc:629:static void node::contextify::ContextifyScript::New(const FunctionCallbackInfo<v8::Value> &): Assertion `args[1]->IsString()' failed.

Our tests all pass on node 10 in Travis.

What makes you think this is a karma-runner bug, since you note: a known issue in Node 10?

[ktajpuri]

I am getting exactly the same issue. I also have node 10. Did you find a resolution?

@ktajpuri
Fix:
Run - npm install natives

[chrisdarroch]

If you have a lockfile, check that you're on at least version 1.1.4 of natives. Prior versions won't work in Node v10.

Help, i dind solve my problem

[johnjbarton]

This does not look like an issue karma-runner can fix: it depends on the installed node environment.
