Unable to generate 'react-keyed-file-browser.js' in 'dist' dir even though npm-build is successful by 'npm prepublish' or 'npm run build' command

Step-1: As I've Windows-10 OS, so modified only the 'scripts' section(build-js, build-css, build) of the 'package.json' as below in order to make the npm-build successful:

"scripts": {
    "publish-demo": "git branch -D gh-pages; git push origin --delete gh-pages; git checkout -b gh-pages; cd demo-site; yarn; npm run build; cd ..; git add .; git add -f demo-site/dist; git add -f demo-site/node_modules/uptick-demo-site/dist; git commit -m \"Demo site build\"; git push origin gh-pages; git checkout master; git push origin `git subtree split --prefix demo-site gh-pages`:gh-pages --force;",
    "test": "echo \"Error: no test specified\" && exit 1",
    "build-js": "node .//node_modules//webpack//bin//webpack.js",
    "build-css": "node .//node_modules//node-sass//bin//node-sass src//browser.sass dist//react-keyed-file-browser.css",
    "build": "npm run build-js && npm run build-css",
    "prepublish": "npm run build",
    "storybook": "start-storybook -p 9001 -c .storybook"
  },

Step-2: Executed 'npm install' or 'npm prepublish' or 'npm run build' to build the project, build is successful, 'dist' directory is created with 'react-keyed-file-browser.css' file. Not seeing the 'react-keyed-file-browser.js' file from the 'dist' dir.

Here is my build-logs after executing 'npm prepublish' command from the console:

D:\React-Workspace\react-keyed-file-browser-master>npm run prepublish
> react-keyed-file-browser@1.4.3 prepublish D:\React-Workspace\react-keyed-file-browser-master

> npm run build-js && npm run build-css
