Windows 10 failure

Trying to run the newest mydomoathome on win7 and getting this error. mydomoathome 0.2.39 runs fine on the same system/node version. Any idea what's could be causing this? note: xxx's for privacy.

empierre, thanks for responding. Here is what I get when I type 'npm' on the command line: C:\utils\nodejs-apps\MyDomoAtHome-nodejs>npm -v 6.14.8

is the syscall 'spawn npm' a newer addiition? because domoathome 0.2.39 works fine. Here is the log when I did a "npm install' on the 0.2.41 release: xxxx>npm install npm WARN deprecated istanbul@0.3.22: This module is no longer maintained, try this instead: npm WARN deprecated npm i nyc npm WARN deprecated Visit https://istanbul.js.org/integrations for other alternatives. npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142 npm WARN deprecated mkdirp@0.5.4: Legacy versions of mkdirp are no longer supported.

I found the cause of this - it involves a long known crossplatform bug on node.js. It looks like the addition of the ability of mdah to query npm version broke cross platform compatibility at some point. There are a few solutions to use. I went with adding the node module 'cross-spawn' lib and then making a change to mdah.js. This fix should be cross-platform compatible:

1. 'npm install cross-spawn'
2. change mdah.js: remove: 2758: const { spawn } = require("child_process"); add: 2758: const spawn = require('cross-spawn');

followup note on this: the reason it broke is "npm" is implemented as a batch script named "npm.cmd" on Windows and the regular jscript spawn does not find things in the path other than '.exe' files.
