Got this error message:

/path/to/test/node_modules/geotiff/src/dataview64.js:1
(function (exports, require, module, __filename, __dirname) { class DataView64 {
                                                              ^^^^^

SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

Still use '--use-strict' switch to workaround this issue.

You can use the built version from the dist directory (which was originally meant for usage in older browsers) and was transpiled using babel. I'm currently preparing a modernized buildchain where the modules to be included are all transpiled.
