Core module subpaths are not supported

Trying to use import modules that specify a subpath aren’t supported and I haven’t been able to find a way to work around it.

Error:

Unable to resolve path to module ‘path/posix’. eslint(import/no-unresolved)

Example:

import { join, parse, relative } from 'path/posix';
import { readFile, writeFile } from 'fs/promises';

I tried the following with this plugin to no avail:

"rules": {
  "import/no-unresolved": ["error", {
      "ignore": ["path/posix", "path\/posix", "path\\/posix"]
    }],
},
"settings": {
    "import/core-modules": ["path/posix", "path\/posix", "path\\/posix"]
}

Similarly, this problem exists with node/no-missing-import but I can use the following workaround:

"node/no-missing-import": ["error", {
  "allowModules": ["path/posix"] 
}]

For anyone that finds this still. VSCode still ships with v12 Node where fs/promises is not available.

You can solve this by adding the following VSCode setting, to use your system node.

{
     "eslint.runtime": "node"
}

@ljharb I am getting it both in the terminal running eslint as well as in VS Code. Let me try to track down what the real fault is then.
