Webpack-cli postinstall script fails to run

[csimi]

There seems to be some sort of module resolution bug.

Reproduce:

docker run --rm node:12-alpine npx webpack-cli@3.3.2 help

Result:

internal/modules/cjs/loader.js:626
    throw err;
    ^

Error: Cannot find module '/root/.npm/_npx/1/lib/node_modules/webpack-cli/bin/opencollective.js'
