Version of nodejs
Based on the screenshots, you are attempting to install the node-sass package.
It's deprecated and, as you can see, depends on a binary module that needs to be compiled separately on Windows using the Visual Studio toolchain.
You have two options:
follow the instructions in the readme to also install the node-gyp prerequisites
switch your project to use the sass module (recommended).

Encounter errors when create react project

When I try to run npm create-react-app <name>, I encounter error reports. I've tried updating my node.js/npm and several other things and just don't work.
as you see in the error message, you have to install the last version of Visual Studio, take a look at node-gyp README, there is a guide to install and configure the dependencies.
suggest: use the npx to initialize a new react project with CRA, this way you will install the latest version each time.

How do I add npm packages into visual studio 2019 with .net core project?

I am using react for front end along with .net core in backend. I am told to to use visual studio 2019 to work with .net core and this is the first time I am using visual studio. I installed react + redux template and I am wondering how can I add npm packages such as react-table or #material-ui/core in my project ? Can I just straight add to dependencies inside package.json file like "#material-ui/core": "version" and will it automatically install when I save ? And also how do I uninstall npm packages as well ?
To install npm packages into your project just simply use
npm install <package name>
To uninstall you use
npm uninstall <package name>
You need to use these commands within the terminal.
You can open a integrated terminal window in vscode:

How do i downgrade expo and install a specific package?

Some of your project's dependencies are not compatible with currently installed expo package version:
- #react-native-community/netinfo - expected version range: 5.5.1 - actual version installed: ^5.8.0
Your project may not work correctly until you install the correct versions of the packages.
To install the correct versions of these packages, please run: expo install [package-name ...]
Im getting this above warning. is there any cli command to do install specific expo package? if yes then please provide it. Thanks.
Into your package.json file, update the version of #react-native-community/netinfo to the right one (5.5.1), and make a npm install again.
You can also provide the version by using the cli command :
npm i #react-native-community/netinfo#5.5.1

Installing Definitely Typed packages in VS 2015 RC AspNet5 using Gulp and TSD

I am trying to install angular.d.ts in my MVC6 application and am running into major headaches.
I have set up Gulp to "REINSTALL" any packages I need using tsd, but I cannot figure out how to get the packages installed in the first place. All the instructions tell me to run tsd install xxx or some such but I cannot get Windows to recognize it. I realize I can add it to my path etc. But everyone seems to think I can just run it. Is there some trick I never learned in VS in regards to this?
You should either:
Install tsd globally: npm install -g tsd.
or
Use local executable: ./node_modules/.bin/tsd.
