webpack-dev-server missing dependency 'hpack.js' - javascript

Starting a new project, I've installed the latest versions of webpack and webpack-dev-server. I've added the webpack-dev-server command to my start script in my package.json. Oddly, the dev server was working the first time I ran the project, but I then blew away my node_modules folder and reinstalled. Since reinstalling I am continually blocked by the following missing dependency error.
npm start
> webpack-dev-server
module.js:442
throw err;

spdy-transport seems to be the culprit, but I am still getting the error even after explicitly running "npm install" on spdy-transports root, and ensuring that "hpack.js" exists.
Has anyone else experienced this missing dependency?

Resolved by running npm i -g npm#latest-4. Some versions of NPM don't correctly set the "main" field of package.json if the package contains a period.

I can't run npx create-react-app or any npm commands including uninstalling or updating npm. Yesterday I installed yarn, could that be part of the problem? I also updated my Mac to Catalina 10.15.5 recently. I'm not sure if either/both of these caused the npm issue or not.
What's causing this and how can I fix it?
Found a solution. A modified version of this answer worked.
I ran:
brew uninstall --force node
sudo rm -r /usr/local/lib/node_modules
brew install node
and that did the trick.

Any suggestion?
You probably have to make a clean install your dependencies again with npm install, as you might have broken some symlinks (just assuming as I'm not a Windows user).
You can manually delete your node_modules folder and run npm install, or if you have an existing package-lock.json, use npm ci to install exactly the same versions of deps you had before.

React: "react-scripts start" cannot find module webpack

I am getting this error when I am not even using webpack in this particular branch. I have never encountered this error in my main branch before. However, I wanted to learn webpack so I created a webpack branch of my project and install webpack in that branch(Assuming that I did correctly install webpack locally). Now when I switch back to my main, and tried to run "npm start". I am getting into this error.

Many SO posts suggesting downloading webpack, but I do not wish to use webpack for this branch, so many SO posts are not helpful.
What I have tried:
I checked my package.json file, there is no webpack dependency in my main branch. However, I do see webpack in my package.lock.json file when I search for the word webpack
What I am using:
I am using create-react-app library.
What I need help with:
I am trying to figure out the cause of this error and how to fix it. Does it have to do with me installing webpack in the other branch?
I faced this when I was trying to use react-scripts in an existing react app that wasn't scaffolded using create-react-app. The problem was the package-lock file. Deleting node_modules and package-lock.json and running npm install did the trick for me.
Ok, this is weird but this is how I fixed it.
I think this error has to do with "react-script"
I was using react-script#1.3, as soon as I upgrade my react script to 2.1.3, which is the latest version published 4 days ago, this error is fixed.
You are using CRA (Create React App) which is already using webpack (with it's own config file). CRA offers the option to 'eject', which will expose the webpack config file that you can then modify and play with. If you do choose to eject, do so on another branch (in case you decide to go back). Be aware that ejecting is non-reversible.
Hope this helps!

Error: Cannot find module ' buffer-shims'

I am working on a Reactjs project and was in the process of installing Electron. Every time I tried to install Electron globally I didn't have permission. I thought that by installing Homebrew I wouldn't run into this problem anymore. However, it created a bigger issue. I uninstalled homebrew to go back to my base. Now, every time I run NPM I get this error message:

I had this problem on my Mac. When I was trying to update npm.
/usr/local/lib/node_modules was owned by root and not by me on my machine.
I did a sudo chown -R <username_here> /usr/local/lib/node_modules on that directory. Then I deleted the whole directory rm -r /usr/local/lib/node_modules and then did a brew uninstall npm and a brew reinstall npm to fix this issue.

Sails lift error 'Cannot find module 'express/node_modules/cookie'

I tried manually removing the 'node_modules' folder, inserting express as a dependency in my package.json and running 'npm install', but that did not work.
Im running Node v6.2.2 Sail v0.10.5 and NPM v3.10.6
What am i missing here?
update sails version to latest, it is issue of npm structure, old version use tree level dependency while new version use same level structure
sails upgrade version
It's a dependency issue with npm, this worked for me when I had the issue.
npm -g install npm#latest
