I am trying to learn how to use blockstack https://docs.blockstack.org/browser/hello-blockstack.html which is a react.js type of application.
When I build the app and run npm install this is the error I receive:

Does anyone know what I must do to fix this error?
These types of node-gyp errors can be caused when Python 3 is installed on the system and it is expecting Python2.7. The node-gyp contributors claim Python3 support is not perfect at the moment and recommend Python2.7 if you encounter any problems.
It may not be necessary though to change Python versions in your case just yet, since it looks like you are on a Windows machine and it's failing on the node-gyp rebuild step. It's probably worth trying the following command first (make sure you are either in CMD or Powershell in Administrator mode:
npm install -g windows-build-tools
The windows-build-tools package is required for node-gyp to work properly on Windows, as stated here. After this, try running npm install again.
Still fails?
If the problem persist or another error related to node-gyp occurs, you might have to install Python2.7 and set npm to use Python2.7
npm config set python /path/to/executable/python2.7
You can read more about possible node-gyp issues and how to resolve them on the node-gyp github page.

I'm using brain.js library for creating Nural network.
Package installed perfectly, but when I ran the server then I get this error.
Cannot find module gpu.js
Then I installed "npm i gpu.js"
Then I got this error - This below error says that install visual studio 2022 latest version and run this in that. I did but didnt worked.

I have cloned my project from git and when trying to do the npm install, it's not working.
I can't fix any of the errors - for example when trying to fix the core-js error with npm install --save core-js#^3 I still get the same message, that I need to upgrade.
Why is this happening? there were no errors before I cloned this repo?
npm WARN deprecated #babel/polyfill#7.12.1: 🚨 This package has been deprecated in favor of separate inclusion of a polyfill and regenerator-runtime (when needed). See the #babel/polyfill docs (https://babeljs.io/docs/en/babel-polyfill) for more information.

Even I faced same kind of issue... might be this may be helpful to you.. :)
I have created a folder called "projects (Folder Name)" in that I have taken the clone of my project - called "xyz project (projects >> xyz project)"..
now by mistake I tried to install - npm install in "projects folder (parent folder)"..
but node modules have to be installed in "xyz project" (child folder)
So when I have used npm i... in xyz project... then node modules have installed SUCCESSFULLY..
Try this..
I'm currently learning how to work with React and everytime I try to work on a course file and run npm install I get back a million errors and warning. On literally every file I try this on. I've made sure I'm inside the right directory and that there is a json file.

I've already tried to reinstall node, update npm to latest version (i'm on 6.14.4) and run npm cache clean but none of those worked. The only thing that worked once was to run a command that was something along the lines of npm install missing dependencies but that's not it, i can't remember it or find it anywhere online now.
You are having a problem with the C compiler of node. Often, this module (node-gyp) is a dependency of one of your dependencies. The problem usually occurs, if not all settings are correctly set. Follow the official installation guide of node-gyp:
Windows: https://github.com/nodejs/node-gyp#on-windows
Mac OS: https://github.com/nodejs/node-gyp#on-macos
You need to install node-gyp
npm install -g node-gyp
When trying to install brain.js, a strange error occurs and I can't understand what the problem is and where does the python come in since this is the installation of a library through npm. I didn't find similar situations in Google (I don’t even understand how to google this).

There is not a word about this problem in the documentation for brain.js. Everything is simple there - run npm install brain.js and that's it.
UPDATE 16.08.2019
This instruction marked option 2 helped me
https://github.com/nodejs/node-gyp#on-windows
Make sure the Path and Env variables are set for the Python installed. Also, I found something similar here.. hope it helps!!
Use the command without dot:
npm install brainjs

If some more info is needed, please comment.
Check if the dependencies of node-xmpp module is installed.
Try to see node xmpp documentation
You need to install first node-expat which is dependent of libexpat library. I tried
yum install libexpat
but it does not exist. I was able to find another library which helps.
Try:
(for CentOS)
yum install libicu-devel
(for Debian 6 system)
apt-get install libicu-dev
Then
npm install node-expat
Then you can install node-xmpp module.
