Why don't I have a local network URL? - create-react-app

After installing and running create-react-app
npx create-react-app my-app
cd my-app
npm start
I see one URL:

Cannot run an app from vue-cli on localhost

I installed the Vue-CLI in version 3.7. Run vue create my-project and npm run serve. Everything was fine and got message
App running at:
- Local: http://localhost:8080/
Though on the http://localhost:8080/ I got This site can’t be reached.
I managed to use vue init webpack-simple my-project and then in ./node_modules/webpack-dev-server/bin/webpack-dev-server.js change port number and with the new one it's working but this "trick" doesn't work for vue create anyway.
Node version 11.11 and OSX Mojave. There should not be anything that could block the port. I have no idea what to do with this.
please run this command in your vue project directory:-
npm run serve
OR
yarn serve
After run command refresh your browser. this command would be run repeatedly when you get 'This site can’t be reached'.
Do this:
Remove your Node.js and again install latest version here
On the installation path choose npm package manager and install
Open cmd and enter this:
npm install -g #vue/cli
After install vue cli (Previous step) enter to cmd this:
vue create name-app
After some minutes (It depends on how fast your internet is) be sure You have the correct installation
So enter in cmd this:
npm run serve
Then you should be able to navigate to localhost page http://localhost:8080
You can override webpack dev host like this:
vue.config.js
module.exports = {
devServer: {
host: '127.0.0.1',
port: 8080,
public: 'localhost:8080',
},
};
Terminal output
App running at:
Local: http://127.0.0.1:8080/
Network: http://localhost:8080/

Vagrant VirtualBox Local Dev Env, Ubuntu, Yarn, Vue CLI 3 - Issues

I am trying to setup a local development environment consisting of:
Ubuntu server vagrant box
My existing vuejs project created using Vue CLI 3 and passed to vagrant via synced_folder
Then run yarn run serve and access this on my host using port forwarding on the vagrant box.
Background:
I have developed a vue CLI 3 project on my Ubuntu 16.04 laptop which is working well, however, I want to move this inside of a vagrant box to keep my local machine tidy. I currently use yarn run serve which works well. I want to be able to run this command inside a new vagrant development environment.
Summary of Problems/Issues:
the vue command is not found after installing its dependencies
permission issues spat out by yarn when attempting to run yarn run serve inside vagrant box
there is an fsevents#1.2.4 message when yarn global add #vue/cli
Provisioning the local dev environment:
The Vagrantfile:
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.define "webserver_dev" do |webserver_dev|
webserver_dev.vm.box = "ubuntu/xenial64"
webserver_dev.vm.network "private_network", ip: "192.168.33.10"
webserver_dev.vm.network "forwarded_port", guest: 80, host: 8888
webserver_dev.vm.network "forwarded_port", guest: 8080, host: 8080
webserver_dev.vm.hostname = "develop.dev"
webserver_dev.vm.synced_folder ".", "/var/www", :mount_options => ["dmode=777", "fmode=666"]
webserver_dev.ssh.forward_agent = true
webserver_dev.vm.provider "virtualbox" do |vb|
vb.memory = "1824"
vb.cpus = "2"
end
end
end
Provisioning of the vagrant box: ubuntu/xenial64 (virtualbox, 20180802.0.0):
sudo apt update && sudo apt upgrade
sudo apt install build-essential libssl-dev -y
# install node and npm:
cd ~
curl -sL https://deb.nodesource.com/setup_10.x -o nodesource_setup.sh
sudo bash nodesource_setup.sh

sudo apt-get update && sudo apt-get install yarn
# Show installed versions
yarn -v (outputs 1.9.4)
node -v (outputs v10.9.0)
npm -v (outputs 6.2.0)
Problems/Issues Output:
When I navigate to my existing vue project folder and run yarn run serve inside vagrant ssh I get the following error:

Running vue --version

No command 'vue' found, did you mean:

vue: command not found
Output from running yarn global add #vue/cli
As shown in the official vue-cli installation documentation
NOTE: The fsevents#1.2.4 message I get. Could this what is causing the problems?

Summary:
Has anyone out there achieved a local development environment where they are successfully able to run yarn run serve inside it and access the result on their host machine?
I would be very interested to see how other developers approach their local development for vue js projects which also have other services requiring reverse proxys (eg node js app running on a different port).
I have spent an awful lot of time trying to set this up to no avail. Maybe these tools just don't play well together. If you think you could help I would be very grateful. Thanks
Temporary Workaround: - inspired by this post
After further troubleshooting I found the problem is certainly a permissions related issue (not related to vue-cli).
I think that as my vagrant is using virtualbox, there is a virtualbox issue with symbolic links from the synced folder from my host, which may change permissions and stops chmod command from having any effect on files. In my case the execute flag from node_modules/.bin directory was not-executable.
For anyone with similar issues here is my current workaround to this issue (Do yourself a favour and read https://github.com/hashicorp/vagrant/issues/713 I wish I'd found it earlier!):
1) copy the projects package.json to: the yarn global directory: /home/vagrant/.config/yarn/global/
cp /var/www/project/package.json /home/vagrant/.config/yarn/global/
2) Install the projects dependencies globally in the yarn users directory:
cd /home/vagrant/.config/yarn/global
yarn install
3) Now returning to the project and running yarn run serve works as it uses the node_modules from /home/vagrant/.config/yarn/global/node_modules/.bin/ which has the correct executable permissions.
cd /var/www/project/package.json
yarn run serve
Example of cause of the issue:
1) Change directory to your project and ls -l to see permissions:
cd /var/www/project/node_modules/.bin
ls -la
Outputs:
lrw-rw-rw- 1 vagrant vagrant 18 Aug 29 00:21 which -> ../which/bin/which
2) Attempt to make file executable:
chmod 777 ./which (adding sudo doesn't make this work either)
Outputs:
lrw-rw-rw- 1 vagrant vagrant 18 Aug 29 00:21 which -> ../which/bin/which
OLD ANSWER - DIDN'T WORK: The solution I am now using is taken from here: Source
Adding this to the Vagrantfile enables symbolic links to work properly.
I am using ubuntu on my host and guest machines so can't be sure this will work for Mac and Windows.
config.vm.provider "virtualbox" do |v|
v.customize ["setextradata", :id, "VBoxInternal2/SharedFoldersEnableSymlinksCreate/vagrant", "1"]
end

You need to use sudo when installing vue-cli.
The vue-cli documentation at https://cli.vuejs.org/guide/installation.html states that:
To install the new package, use one of the following commands. You
need administrator privileges to execute these unless npm was
installed on your system through a Node.js version manager (e.g. n or
nvm).
npm install -g #vue/cli
# OR
yarn global add #vue/cli
