** Using WeBWorK **

Glenn, thanks for your help. We restored our WW server back to its state before trying the upgrade so I could start over from scratch with your suggestions. This got me much farther into the upgrade instructions. But I got stuck at:

Then run npm to install (or upgrade) third party javascript and minimize local javascript and css:
> cd /opt/webwork/webwork2/htdocs
> npm install

This is the result
> prepare
> npm run generate-assets

npm ERR! code 243
npm ERR! path /opt/webwork/webwork2/htdocs
npm ERR! command failed
npm ERR! command sh -c npm run generate-assets

npm ERR! A complete log of this run can be found in:

Here is the completge log

When I try to log into Webwork, the page loads but is missing css styling and there is a warning message
ERROR: '/opt/webwork/webwork2/htdocs/static-assets.json' not found!
You may need to run 'npm install' from '/opt/webwork/webwork2/htdocs'. at /opt/webwork/webwork2/lib/WeBWorK/Utils.pm line 1875.

which seems to be a consequence of the original difficulty with running npm install in htdocs. If I enter the admin id and password, then click on the continue button, nothing happens.

Incidentally, running npm install in pg/htdocs worked with no problems.

Do you have any suggestions for what I need to do to resolve this npm install issue in webwork2/htdocs?
