回答1:

Looks like mean stacks postinstall script is hardcoded with Unix style paths. In Unix ./somethig/or/another signifies accessing the something directory starting HERE (the meaning of .).

I'd suggest submitting a bug on their GitHub page to start. Then you might be able to get away with editing the package.json to have the post install script use Windows style paths. It would be something like node_modules\bower\bin\bower install. I don't have windows so cannot say for certain.

The postinstall doesn't work really well now for this repository on Windows. Try to run npm install -g bower and then bower install in the project's folder. It should do the same thing without postinstall.

If you want to call something from node_modules/bin, you don't have to point at it directly. You can just call the tool by name in NPM script definition, i.e.:

"postinstall": "bower install"
