HelloWorld vert.x not starting - javascript

I'm trying to get a vert.x HelloWorld project running based on this: https://vertx.io/blog/vert-x3-says-hello-to-npm-users/
I've done npm init and installed vertx3-min 3.8.3. But when i execute "npm start" I get the following error:
vertxdemo#1.0.0 start C:\Users\Tiago Redaelli\Desktop\VertxDemo
vertx run server.js

PS C:\Users\Tiago Redaelli\Desktop\VertxDemo>
The part trying to start server.js taken from the example looks like this:
"start": "./node_modules/.bin/vertx run server.js"
This is the project directory
Update
After installing vertx 3.8 and setting the path to C:\Program Files\vertx\bin I can enter "vertx version" but it still complains over the contents in the shell file as seen previously.
This is the file referenced by the start command:
#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
case `uname` in
*CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;;
esac
if [ -x "$basedir//bin/bash" ]; then
"$basedir//bin/bash" "$basedir/../vertx3-min/vertx/bin/vertx" "$#"
ret=$?
else
/bin/bash "$basedir/../vertx3-min/vertx/bin/vertx" "$#"
ret=$?
fi
exit $ret

You're on windows operating system, so your start script should be the bat one:
vertx.bat
Try replacing the previous commands with that one instead and your application should work.

I don't understand why did I get such errors? Now I'll try to describe you detailed what I did I made several steps:
Download the latest node.js version via https://nodejs.org/en/download/
I set NODE_HOME in system variables
Created empty folder
Opened empty folder in command prompt, (cd 'path to this empty folder')
Wrote 'npm init wdio .' into the command prompt
Then I just chose the default options
I was waiting and such errors appeared
I tried to update npm to the latest version. It doesn't help.

Cant build React app - pipeline fails miserably

So there is the error "can't find file" but actually THERE IS a public directory with the index.html file inside. I don't know why this is happening...
Edit: Im adding the docker file used in config pipe
# -- Base node --
FROM node:13.7-alpine AS build
WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
ARG BUILD_ENV
RUN npm run build ;
# -- final build --
FROM nginx:1.17.8-alpine
COPY --from=build /app/build /var/www
COPY nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
I notice you are running this on docker, so you did wrong on docker during copy your react app directory to docker container.
You have not added your Dockerfile code here
So we suggest you to fix your dockerfile first. Also check your .dockerignore file and debug getting into docker container, if the directory exist there or not
So your docker file should be similar to this
COPY . ./
RUN npm run build
It should be like this (Not . /app):
# Copy other project files and build
COPY . ./
RUN npm run build

I keep getting this error after typing npm start into the terminal

I keep getting these errors. Recently developed a simple web app and posted on my repository and kept getting these errors thereafter.

i kept getting erros even after deleting the node modules and package.json, i uninstalled node and installed again, ran npm innit to get my package.json and i got this error
'CALL "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" prefix -g' is not recognized as an internal or external command,

ENOENT means no such file or directory, meaning something being referenced by some process doesn't exist where the process thought it did, such as the node executable, cmd.exe, or the react-scripts executable in node_modules. In this case it seems to be a Windows-specific issue. Adding cmd.exe to your path may fix things. See this question for more.

I am receiving this error and because of that I'm not able to: npm run dev-server.
Is there a way to replace ./ part?
Just refer to the binary directly:
"scripts": {
"dev-server": "webpack-dev-server --config config/webpack.config.js"
},
npm will run the script in an environment where all the installed packages' binaries (namely node_modules/.bin/) are directly available in PATH, including webpack-dev-server.
Also using / as a path separator is preferable in package.json - it works on Windows as well as Linux or OSX.

Node.Js and Socket.IO application on Heroku

I am having this error message when I try to deploy my application on Heroku. Any suggestions? I can easily deploy my app on localhost but it doesn't work on Heroku.

It seems hiredis is indirectly needed by express, which you have a release candidate version, which might be the problem. Try to change express to:
"express":"3.x"
Also, make sure you don't commit the node_modules directory to your git repo. Add it to .gitignore!
