npm Error Failed at the node-sass#4.9.0 install script

I received This error when I am trying to run "ionic start MyApp" on windows terminal.
I am running from a new machine and I already tried to reinstall nodejs and ionic but the same error is coming all the time.
Can anyone help me?

Try installing the latest version of ionic:
$ npm cache verify
$ npm i -g ionic cordova
If this doesn't work, you need to install the library minimatch manually:
$ npm i --save minimatch

Solve the problem with those steps:
$ npm uninstall cordova ionic
$ npm cache clean -f
$ npm install npm -g
Then uninstall nodejs, reinstall again and reinstall ionic cordova
$ npm install -g cordova ionic

parse-server fails to start

I have followed the commands below (https://github.com/parse-community/parse-server) to install parse server locally.
$ npm install -g parse-server mongodb-runner
$ mongodb-runner start
$ parse-server --appId myserver --masterKey myserver --databaseURI mongodb://localhost/test
the server files are downloaded and stored at ~/.npm-global/lib/node_modules/parse-server.
when i try to run the 3rd command
parse-server --appId myserver --masterKey myserver --databaseURI mongodb://localhost/test on the terminal, I get the error below
parse-server: command not found
When i try to run npm start on the terminal from the same folder, I get the error below
parse-server#2.7.4 start /home/user/.npm-global/lib/node_modules/parse-server

how can i run it?
Another thing, I had already installed mongodb and was using it before trying to install parse-server on my laptop. did
npm install -g parse-server mongodb-runner
mongodb-runner start
install another mongo db on my laptop?

I was able to solve the problem by updating my nodejs version from 4.2.6 to 8.11.1 using the commands below
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
After that, I added parse-server path to /etc/enviroment file
sudo gedit /etc/enviroment
appended this line :~/.npm-global/bin
then I run source /etc/enviroment command
and was able to start parse-server from the terminal
parse-server --appId myserver --masterKey myserver --databaseURI mongodb://localhost/test

Webpack config not in strict mode, don't want to change the code

I trying to build production webpack of BitShares UI
https://github.com/bitshares/bitshares-ui
The issue is that webpack is not running in strict mode
I don't want to have to change the code though. Is there a way to force that webpack config is interpreted in strict mode so that I avoid this problem?

Please check your nodejs version.
BitShares-UI depends node Node.js, and version 8+ is required.
On Ubuntu and OSX, the easiest way to install Node is to use the Node Version Manager.
To install NVM for Linux/OSX, simply copy paste the following in a terminal:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash
nvm install v9
nvm use v9
After this run npm run build

Go you your 09-mongodb folder, then run npm install command, then run npm run start.
npm install -
This command installs a package, and any packages that it depends on.
If the package has a shrinkwrap file, the installation of dependencies
will be driven by that.
By default, npm install will install all modules listed as
dependencies in package.json.
