React start up problem with new react app windows [solved] - node.js

Hello i am not really sure how to explain my problem or how to ask for help.
But am going to try it anyway lately when i create a react app it installs like normal.
But from the moment i use npm start i get this error (npm start error terminal).
Which says it has nothing wrong with node js/npm so i suspected it was something about the react app dependency that was wrong. When i downgrade to a older version of react scripts it works but the newest version 16.13.1 doesn't work even tho i use this version of react on my windows laptop. In case it helps to solve my issue here is the error log that npm generates (error log npm) i hope this helps to solve my issue

I have found the solution for my problem by setting the path value for system32.
You can do this by the following steps
Goto > Control Panel\System and Security\System\Advance system setting\Enviroment variable and set system variables path C:\Windows\System32\ variable and restart your System.
After i have done these steps it seems to work

Node cannot run serverless cmd

I tried updating both Serverless module and Node, but still receives the same error.
I count not even find the solution in the internet for this simple problem.
can someone suggest.
The issue for me was that I was missing the following directory in my Windows PATH env variable:
%AppData%\npm
Once I added that I could run serverless, SLS, etc.
Don't forget the restart your PC.

Why does my computer keep forgetting node and npm installation?

My computer keeps forgetting that I have node installed despite the fact that all of the files are still there. So far, I have tried installing through the node installer on the nodejs website, using brew, using nvm, and also several of the suggestions in this gist. No matter what I try, within a couple of hours or a couple of days, I am working away and then I am suddenly throwing node errors, and when I check node -v or npm -v, I get the error command not found: node or command not found: npm. The only thing that I can figure out to get node working again is to uninstall whatever I most recently tried and then to reinstall.
It seems like I might be having some sort of env or path issue, but I don't know where to begin to start troubleshooting anything like that.
EDIT
Based on the suggestion below, I added these to my .bash_profile and it seems to have fixed my issue. Not sure why the install wasn't adding them here or in .bashrc, but adding it manually fixed the issue:
export PATH="$HOME/.npm-packages/bin:$PATH"
export PATH="$HOME/.node_modules/bin:$PATH"
maybe you forgot to add node & npm binaries to your path that's why when you open a new instance of your terminal it says that it doesn't know node and npm
Simply add the line that register the binaries into your path within your .profile file that might be located in your home directory

Issues running React app on Windows environement

I have a working react app that I had hosted on a linux environment, but the client has switched their hosting provider and now I have to run the app on a Windows environment. I personally am unfamiliar with Windows and having some serious issues getting my app to work now.
After loads of debugging and testing I now can get my app to run, but when I start it, it will throw some errors which will results in a broken app in the browser.
So when I run npm start it will start up the app and spit out this error:
Screenshot of the terminal error 1/2
Screenshot of the terminal error 2/2
It seems to spit out some complaints when using npm run watchJS which runs this command babel src --watch --out-dir lib.
I am completely lost at this point and have no idea where to go from here.
I can provide as much detail as anyone needs after looking at the question, I just don't know what else to add to this issue and don't want to fill up this question with irrelevant info.
Thanks in advance for any help
It is likely a bug with the version of npm you are using.
See this thread:
https://github.com/npm/npm/issues/18380
Try rolling back your version of npm to 5.3
The issue appears to be exclusive to windows with babel packages.

const INLINE = 'inline'; with npm related commands

Today I was trying to work on Angular2 (template https://akveo.github.io). As per installation guide, I ran following commands.
I have installed Node.js v6.9.1.
npm install --Worked fine.
npm server --Failed with below error.
E:\........\node_modules\script-ext-html-webpack-plugin\index.js:3
const INLINE = 'inline';
^^^^^
SyntaxError: Use of const in strict mode.
at exports.runInThisContext (vm.js:73:16)
at Module._compile (module.js:443:25)
After many random searches and failing to resolve it, I decided to think about it with a calm head. To me it looks like it is a problem with ES2015/ES6. Package script-ext-html-webpack-plugin uses const variable which is a ES2016 feature. However system is unable to resolve it.
Also this problem can come with any package like hapi, selinium etc. But everything should have same solution I guess.
I have tried many related commands on the installation guide of the website mentioned above but nothing works and ends with same error. I have also many have faced same issue online but nothing concrete is visible as answer.
Could anyone help me out?
Update
Below approach has also fixed many of my colleague's machine who were facing some random errors with nodejs.
This problem is resolved in at least my machine. I am certainly not a person who understand nodejs completely but got it working after some googling. The solution given below may be common to many other issues I guess.
The system I am working has Windows 10 as Operating System and has 64 bit processor.
Go to control panel and uninstall nodejs (just to make sure you do not have traces of any previous install).
Install latest version of nodejs from their website (I installed v6.9.1 for 64 bit processor).
Go to Environment variables for system (just type environmental variables in start menu if using Windows 10) and edit the Path. Delete ‘C:/Program Files (x86)/nodejs’ (as I had installed 64 bit nodejs). This ensures when using command you do not use any other previously installed nodejs.
Start command prompt in Admin mode and navigate to your project and run npm install.
In case you get any/some error, then run npm info graceful-fs -v or npm info graceful-fs whichever runs in your machine.
Then run npm update -g npm.
Then run npm install again and this time it should work.
Run npm start and everything should work fine.
On running website, sometimes we see any other issue and that can be seen from console logs. But good thing is, console logs also tell you the problem. In most cases its related to 32 bit and 64 bit processor due to our recent changes. In my case, I was facing issue with SASS configuration due to 32/64 bit machine and console log asked me to run npm rebuild node-sass to fix the issue.
Go back to command prompt, hit Ctrl+C to stop npm server. Run node rebuild node-sass. Run npm start again and everything should be working.
Hope it helps.

Cannot find module 'assetmanager'

I'm trying to run the MEAN stack on windows. I've installed all the pre-requisites (I think) but when I try to start the server via the gulp command I get the error:
Error: Cannot find module 'assetmanager'.
IMAGE:
I have tried running npm install assetmanager which run fine but I still get this error.
This is my first time trying to run node on a machine (I should have used a linux box) so go easy on me as I am learning :-).
Any and all help appreciated.

I had exactly the same problem on Linux Mint 17.2.
The failing way: This was my first project that I'd generated and I don't think I had all the dependencies installed before I ran the init command (g++ was missing).
I tried the npm install assetmanager command as you did and then install worked. Running gulp after this, it got further but this time I was missing mongoose. I installed that then it couldn't find .../config/env/all so I sylinked the default.js config. Then running gulp again, errorhandler was missing. I figured it shouldn't be this hard so...
The working way: I deleted that failure of a project and init'd a new one and it worked. Unfortunately I'm not sure if the init didn't work the first time but I missed the error/warning or something else caused it. All I can recommend is try creating another project and see if that works.
