I have created a new node (MERN) app on my mac osx. Im learning (from rails).
I don't know why, but whilst I do have a package.json file, I cannot generate a node_modules folder. I have tried all of the suggested answers in this post.
When I go to the terminal and test:
ls node_modules
I get a long list of all the modules listed in my package.json (but no node modules folder in my app file in atom).
That list includes all of my babel modules.
When I try to start the app, I get an error that arises out of my using import statements instead of require (which I should be able to do if babel were working).
node server.js

Does anyone know how to configure a new node app so that it generates the node modules folder? Apart from the post above, I can't find any suggestions on how to work through this problem. The answers in the post linked above haven't worked.
hi you may want to make sure you are in the directory of your folder
e.g.
cd Desktop/My_Project
The safest way is the then run npm init get all the required things fill out and run npm install --save babel-core at this point you should be able to see the node_modules folder found in "Desktop/My_Project/node_modules"
Try this out and hope this helps :D

I am new to Bubblewrap. I downloaded Node.js and then did npm i -g #bubblewrap/cli. It threw some warnings, but it did finish.
After this, when I am doing bubblewrap init --manifest https://beegle.app/bpro-manifest.json, I am getting some errors which I don't understand and don't know how to solve.
Here are the error messages:
[Mukeshs-MacBook-Air:beeglepro-bubblewrap mghatiya$ bubblewrap init --manifest https://beegle.app/bpro-manifest.json

What is going wrong?
It looks like I had old version of Node.js installed and for whatever reason, even though I had just downloaded Node.js from the website, the latest one was not loaded or it was not loaded at the correct place or whatever.
So basically warnings thrown by npm i -g #bubblewrap/cli were indeed strong ones and it had not completed its job.
I upgraded to the latest Node.js version with nvm install node --reinstall-packages-from=node and now the errors that I posted have gone in the bubblewrap init action.
Of course, as is the case with all development things, now I face the new errors and warnings.
I was using Windows with npm in version 8.16.2 (nvm). Thanks #mukesh for pointing that point. Following nvm list and nvm use 14.18.0, I reinstalled bubblewrap and the bubblewrap init command worked this time.
I am attempting to create a nuxt app in the command line, going to build a Vue web app running off this and Vuetify. I am not sure what I am doing wrong but I run the exact scaffolding command that the docs tell me to run and it errors out everytime with this message.

Has anyone else run into this, google searching is turning up nothing, figure I would check here to see if anyone know what might be up.
Thanks!
I determined that is-promise pushed a commit 2 hours ago that broke.
They are fixing it sounds like.
I am not an expert in Vuejs or Vuecli, but I do manage to get stuff working.

The package.json file is right there in the root director and also the .lock file. Dont know what is the reason for this error in compiling.
Any help hightly appreciated
As #vesperknight mentioned in the comment, this issue tends to happen when you move the project's folder to another location.
To solve this (on Linux), from the root directory of your project:
Delete existing node modules.
rm -r node_modules
Reinstall all dependencies:
npm install
The first step seems to be important.
I'm new to npm and I can't understand how to run a tutorial I found on GitHub. I suspect it has something to do with my lack of knowledge of npm
The tutorial is this one: https://github.com/IrfanBaqui/react-router-v4-tutorial
I'm on Windows 7.
I first tried running serving the index.html pages inside each folder via XAMPP... however, that didn't work (I just get a blank page).
Next, I tried navigating inside a folder via the command prompt and running npm start... that didn't work either... (I do have npm and node.js globally installed)
I get this error:
Cannot find module 'webpack'

Advice would be appreciated.
Inside each sub folder you need to do
npm install it will install every lib you need.
npm start it will run the project
The server should be running. To access the site it should be localhost:9000
Well #sheplu has already answered your question. I would just like to let you know why it is needed.
It is a node project. The guys whose code you are trying to run have used many of the dependencies for each lesson (each folder in his repository).
what npm-install does is, download and resolves all the dependencies used in the project specified in the file named package.json. So, whenever you see a file package.json it would be there specifying dependencies for dev or prod environment.
So, run npm-install in the directory where you see package.json file.
There can be another file bower.json with the same purpose (listing the required dependencies). if you see bower.json, you should run bower-install in that case.
And finally the script to run the project. npm start in your case.
And the error you just posted is clearly saying that some-module not found or could not resolve or something like that. That is because, you've resolved the dependencies required, which you'll have to using npm-install or bower-install for package.json and bower.json respectively
I'm attempting to use the React Starter Kit with SemanticUI on Windows. I can install and build RSK, but when I run npm install semantic-ui and go through the set up, I always hit the same module error and I am unsure how to solve it.

I have tried nuking the directory and reinstalling multiple times, but I am unable to get this to work. What is causing the issue?
You may be hitting the same issues people are having on npm 2701. The issue appears to be related to version updates between installing NPM modules (from a quick read over the later parts of the report). Suggestions include running:
npm set registry https://registry.npmjs.org/
And alternatively, removing all currently installed node modules including globally installed modules (in /usr/node-modules/ or C:\Program Files\nodejs\node_modules for example). The user deleted them manually (i.e. not using npm).
I also faced same issue while running react app. I simply installed it
npm install inflight
Although after it there prompt another error msg which was failed to find moudule 'source-list-map' then I installed it as well
npm install source-list-map
I hope it will help you
