What is preventing eslint from installing based on my error code? - terminal

I am following a Udemy course and the first app we are building through Atom is called albums. I have installed linter and linter-eslint in Atom, but running this code:
npm install --save-dev eslint-config-rallycoding
leads to an incomplete install.
My first line reads:
deprecated eslint-plugin-class-property#1.1.0: please use eslint-plugin-babel and babel/semi
But the second line of my log reads:
#babel/plugin-check-constants#7.0.0-beta.38 requires a peer of #babel/core#7.0.0-beta.38 but none is installed. You must install peer dependencies yourself.
So after that, every line starts off with SKIPPING OPTIONAL DEPENDENCY.
So I am just trying to see what I may be missing or if this even is a problem?

Can't properly install hardhat using Powershell! Persistent Error HH12: Trying to use a non-local installation of Hardhat, which is not supported

Below is a short list of my setup until I stumble upon the HH12 Hardhat Error that I keep getting:
mkdir wave (Name of my directory)
cd wave
npm init -y
npm install —save-dev hardhat
npx hardhat
Choose sample project
6a. Hardhat project root (Select)
6b. Add .gitignore
Say yes to everything
install the remaining dependencies: npm install --save-dev #nomiclabs/hardhat-waffle ethereum-waffle chai #nomiclabs/hardhat-ethers ethers
npx hardhat accounts (to see all the different accounts)...
...And then it fails here! An HH12 Hardhat Error Message: "Hardhat is not installed or installed globally. You tried to run Hardhat from a global installation or not installing it at all. This is not supported. Please install Hardhat locally using npm or Yarn, and try again." (https://hardhat.org/errors/) [BTW, these 2 lines are the ONLY docs on this error on Hardhat!].
Any suggestions?
I have tried the following possible 'fixes' to sidestep this error but to no avail:
Updating most current version of node
Restarting my PC (About 17 X now as of this writing)
Using GitBash (Instead of Powershell)
Asking mods in Hardhat Discord (None) and other Discords
Opening the Hardhat docs (And the Tutorials!!) for answers... None!
StackExchange - There's literally only 1 other person who ALSO had this problem here! But the answers here are not the solution. (Have DMd that person but no reply as of yet).
So can anyone out there help?
I believe I finally figured out the solution (at least what worked for me):
I dropped back 2 directory levels from where I was for my root project and started again there.
I updated my Node version to 16.

Getting error: no matching version `^2.0.0` found for package `codec`?

Question
I'm new to Substrate and going through Add a Pallet to Your Runtime. At first, running the command cargo check -p node-template-runtime gave me error
error: failed to parse manifest at `/Users/bashar/work/substrate/start/substrate-node-template/pallets/template/Cargo.toml`
Caused by:
feature `rename-dependency` is required
consider adding `cargo-features = ["rename-dependency"]` to the manifest
I added it and then I started getting this error:
error: no matching version `^2.0.0` found for package `codec`
location searched: registry `https://github.com/rust-lang/crates.io-index`
versions found: 0.0.0
required by package `frame-benchmarking-cli v3.0.0`
... which is depended on by `node-template v3.0.0 (/Users/bashar/work/substrate/start/substrate-node-template/node)`
I tried modifying the codec version to 2.0.1 with no luck. My setup
rustup 1.23.1
rustc 1.50.0
cargo 1.30.0
Any idea what I'm doing wrong?
UPDATE
I went back to the Create Your First Substrate Chain, which this tutorial is built on, started from scratch, which the Pallet tutorial is based on. And this time, after cloning the repository for first tutorial, cargo build --release failed with the same error feature rename-dependency is required.
This built fine the first time before I moved to the second tutorial. Which makes me think maybe a recent Mac update ruined something? I even tried uninstalling Rust and re-installing it, then installing a new template. Same thing

`npm install` issues/failure with expo-cli and react-native-app

I really need some help with what seems to be the most basic task (setting up the expo/react-native project). I've installed the expo-cli (v3.11.7), react-native (v2.0.1), watchman (v4.9.0) and node (v12.14.1). I've followed the tutorial up until the point where I need to run expo start and I get the following error:
Your project is in SDK version >= 33.0.0, but the expo package version seems to be older.
Error: node_modules directory is missing. Please run npm install in your project directory.
Couldn't start project. Please fix the errors and restart the project.
Set EXPO_DEBUG=true in your env to view the stack trace.
I've then run npm install and tried again but the same error pops up. I've removed the node_modules folder and that didn't work either.
Update:
When I npm install this is the error I'm seeing:
npm WARN deprecated core-js#1.2.7: core-js#<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js#3.

I've installed yarn (v1.21.1) and tried installing using this with the same error:
warning expo > fbemitter > fbjs > core-js#1.2.7: core-js#<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js#3.

Can anyone advise?
I've managed to solve the problem. I was trying to install over my home network, which apparently has some proxy restrictions! No idea why.
Someone advised me to try again but connected to another network or my mobile hotspot. I tried this and it worked! Problem solved. So I guess for any others that may be experiencing the same problem, try connecting to another network and see if that helps.
If this fails, then I suppose looking at the proxy configuration and making changes there may help. But I wouldn't advise doing this unless you know exactly what you're doing.

How to deploy Elm and Phoenix Elixir to Heroku?

When trying to deploy a Phoenix/Elm project to Heroku I run into the following issue:
Running default compile
Elm compile: Main.elm, in web/elm, to ../static/vendor/main.js
/bin/sh: 1: elm: not found
17 Jul 15:58:21 - error: Compiling of web/elm/Main.elm failed. Command failed: elm make --yes --output ../static/vendor/main.js Main.elm
/bin/sh: 1: elm: not found
Check your digested files at "priv/static"
I'm using the buildpacks for Phoenix found in the guides and brunch/elm-brunch.
The error is caused by the elm binaries not being installed. One way to install elm is by using npm, which is already available as the Phoenix buildpack uses it.
Solution: Add elm as a dependency in package.json. This will cause the Phoenix buildpack to install elm before executing the brunch script.
Note that a local computer may have a separate installation of the elm binaries, potentially causing confusion. As long as versions match, this ought not be a problem. Note that to use the elm binaries installed by npm above, one has to include ./node_modules/.bin in ones PATH (which the phoenix buildpack does). E.g. if one has a separate elm installation which is included in PATH since before, this will be used when running commands from the prompt.

Swagger-editor running locally shows empty page

I am new to swagger.
I have created APIs in django-rest-framework. I want to document them. Hence reading about swagger.
I tried django-rest-swagger but because of lack of documentation I could not make my code suitable for documentation.
Hence I am trying swagger editor which will allow me to design API structure from scratch. I have installed it locally but it is showing me empty page at "127.0.0.1:9000". what should I do now ?
I want to write YAML or JSON file that will be consumed by swagger-editor installed locally. How can I achieve this ?
This is the error on console when I load 127.0.0.1:9000
Warn: could not find module util
http://127.0.0.1:9000/bower_components/angular-schema-form/dist/schema-form.js Failed to load resource: the server responded with a status of 404 (Not Found)

I'm not exactly sure what is the problem here. As a general note, you can always clean up npm and Bower modules and start from clean state again.
npm cache clean
rm -rf node_modules
npm install
bower cache clean
rm -rf app/bower_components
bower install
npm start
I was having the same problem.
Previously my node version was the latest v6
I reinstalled everything and then install v4.4.4
node --v
make sure it's v4.4.4
npm install -g http-server
wget https://github.com/swagger-api/swagger-editor/releases/download/v2.10.1/swagger-editor.zip
unzip swagger-editor.zip
http-server
don't use http-server swagger-editor
