Sample script from Getting Started fails with Unexpected token import

See original GitHub issue

The sample script in the Getting Started section of the readme is failing with Unexpected token import error. It seems the reason is that node 8 didn’t have import. OS is Ubuntu 20.04.

> node -v
v8.11.4

Same issue here:

You’re using Node 8 in 2021. I think that might be your problem.

That’s what the readme says: use version 8.11!

If I switch to the latest version of node/npm then I get an error installing the library. What version should we use?

$ node -v

Please use the latest version of Node and the SDK. If that doesn’t work try installing with yarn.

npm install --global yarn
yarn add opensea-js

Please follow this issue for the latest updates on the npm install: https://github.com/ProjectOpenSea/opensea-js/issues/471

I will close this out to avoid duplicates and confusion!
