Observations

[Ignore this: I believe the current version is 4.1 yet despite looking and trying several times, I seem to be downloading 4.0.0 each time I try. ]

Edit - downloaded 4.1.1 from another computer. This gives same error and also does not have the node_modules dir.

I last looked at this on Feb (at v4.0.0)and running the same NPM command in that older directory works. Comparing the two directories, the one I used in Feb has a node_modules sub dir and the current ZIP does not (nor does the git appear to have one).

Is this my problem, and if so why is node_modules missing from the ZIP file today?

Answer 1

Generally it's not recommended to include node_modules when publishing to the web.

Instead users are expected to install the packages using NPM (in this case). Just run npm install, and NPM will create the folder for you.

Ps. NPM finds the module list from package.json
