I did the following to install react-webcam,
sudo npm install -g --save react-webcam
npm WARN react-webcam#3.0.1 requires a peer of react#>=15.3.0 but none is installed. You must install peer dependencies yourself.
npm WARN react-webcam#3.0.1 requires a peer of react-dom#>=15.3.0 but none is installed. You must install peer dependencies yourself.
+ react-webcam#3.0.1
added 1 package from 1 contributor in 0.351s
but it wasnt added to the dependencies in package.json, So how can I add it to the node modules?
I am installing material-ui: npm install #material-ui/core (which is the latest version) for React.
I got the latest npm version (npm i -g npm, which is now + npm#6.1.0).
And I also have tried: npm install --save material-ui.
But it always keeps showing me this:
$ npm install #material-ui/core
npm WARN ajv-keywords#3.2.0 requires a peer of ajv#^6.0.0 but none is installed. You must install peer dependencies yourself.
#material-ui/core#1.2.1
updated 1 package and audited 14597 packages in 8.235s
found 0 vulnerabilities.
I don't know if this is a material-ui latest version problem? or it is the latest npm problem? So, how do I proceed to install the material-ui for React?
You need to install ajv#^6.0.0
npm install -S ajv#^6.0.0
Edit: to add to this, as described in this post, it seems that npm removed the automatic installation of peer dependencies on npm 3, but if you'd like that to be taken care of automatically, you can use npm-install-peers
Whenever I do a npm init then npm install react - I get this error

npm install react --no-optional
Inside your project directory, can you please first run the following commands:-
1) rm -rf node_modules
2) Try installig react again now and other packages which are in your package.json file.
I was trying to install dependencies which resulted in this warning:
npm WARN angular2-in-memory-web-api#0.0.12 requires a peer of #angular/core#2.0.0-rc.2 but none was installed.
npm WARN angular2-in-memory-web-api#0.0.12 requires a peer of #angular/http#2.0.0-rc.2 but none was installed.
I then tried to manually install #angular/core#2.0.0-rc.2 so i used:
npm install -g #angular/core#2.0.0-rc.2
Which also resulted in
npm WARN #angular/core#2.0.0-rc.2 requires a peer of rxjs#5.0.0-beta.6 but none was installed.
npm WARN #angular/core#2.0.0-rc.2 requires a peer of zone.js#^0.6.6 but none was installed.
I then used
npm install -g rxjs#5.0.0-beta.6
npm install -g zone.js#^0.6.6
Which threw no warning. I then proceed to again install #angular/core#2.0.0-rc.2, but it threw same warning as before, like those two modules weren't installed at all. Has anyone met similliar problem?
What is causing this? I am trying to wrap my mind about it but can't find a solution, is there a way how to fix it?
Thanks for help.
Currently failing to learn how to use terminal as a development tool.
Trying to set up the MEAN stack by using yeoman to scaffold the project. However, when I run npm install -g generator-angular-fullstack it installs successfully here (/Users/xxxx/npm/lib/node_modules) and then when I run yo angular-fullstack it says I haven't got that generator.
I have two generators installed already but the new generator (angular-fullstack) isn't adding to the list even though the global install was successful:
mean
meanjs
This might be irrelevant but when I try and uninstall these generators I get this message - npm WARN uninstall not installed in /Users/xxxx/npm/lib/node_modules
What I'm trying to do is:
1. install the angular-fullstack generator
2. scaffold a project using angular-fullstack
I've tried uninstalling yeoman, npm, clearing npm cache and all sorts of things but I can't get it to work. I've been working on this on and off for about 3 weeks now and all I want to do is get a mean project structure set up and running. So if anyone can help that'd be great.
Being a rookie I didn't want to resort to Stack Overflow, but I'll take the abuse now. ;)
Thanks in advance.
UPDATE: Tried to install a different generator (angular) and can't access this either. This is the message I get when installing.

First, you'll need to install globally yeoman and these required tools:
npm install -g yo bower grunt-cli gulp
