I am new to Angular2 and trying to setup the environment with the boilerplate code https://github.com/mschwarzmueller/angular-2-beta-boilerplate.
My dependencies installed fine with npm install but when I run npm start I start to get the below statements. I don't think its an error but its hard to figure out as to what it really means.
$ npm start
> angular2-boilerplate#1.0.0 start C:\Users\user\desktop\angboiler\angular-2-beta-boilerplate
> concurrent "npm run gulp" "npm run lite"
I tried installing run lite, concurrently separately but that didn't work. I even ran npm update -g && npm install -g concurrently lite-server typescript
to make sure i have stuffs updated to make it work but still no progress.
I have: typescript 1.8 version node 4.4.5 version running.
Alternatively, perhaps you would be interested in using Angular CLI, which seems to be the official boilerplate for Angular 2.

Since 3 days ago my nodemon wasn't able to launch from every single project folder. When trying to launch it, it displays this:
$ nodemon app.js
C:\Users\asus\AppData\Roaming\npm/node_modules/node/bin/node: line 1: This: command not found
Note that I have have updated my node to the latest version and npm was initalized. This really is blocking my developement so any help would be very much appreciated.
nodemon install globally and try
npm install -g nodemon
I recently switched to Ubuntu, whenever I create react app it's giving me this note, and the app it's creating is a class component.
ankit#gram:~/Documents/Development/React/react-project$ npx create-react-app my-app
Creating a new React app in /home/ankit/Documents/Development/React/react-project/my-app.
Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts...
added 987 packages in 39s
22 packages are looking for funding
run `npm fund` for details
Success! Created my-app at /home/ankit/Documents/Development/React/react-project/my-app
Inside that directory, you can run several commands:
npm start
Starts the development server.
npm run build
Bundles the app into static files for production.
npm test
Starts the test runner.
npm run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!
We suggest that you begin by typing:
cd my-app
npm start
Happy hacking!
Note: the project was bootstrapped with an old unsupported version of tools.
Please update to Node >=14 and npm >=6 to get supported tools in new projects.
my node version: v16.14.0
my npm version:8.3.1
I think this was because npx was not installed in my system, when I created a react app by this command create-react-app the app created was fine. I also installed npx using this command npm install -g npx and created a react app and everything was fine. before this make sure you have installed create-react-app in your system if not then install it by using this command
sudo npm install -g create-react-app
I am a new programmer had this issue not long ago I just solved it.
Use sudo apt install nodejs
It will automatically install version 10 for you which doesn't accept React.
Then you try to install NVM package, use it to update your node to a newer version.

I was having the same problem after I had just installed Ubuntu 22.04.
The fix for me was updating node and npm by following these instructions free code camp update node and npm
Specifically, I followed the instructions under the heading "1. Use NPM to Update Your Node Version", to update node and ignored the 2nd and 3rd headings, then followed the instructions under the last heading to update npm
afterwards I restarted my computer, opened the project directory and ran the command
npm i create-react-app#latest
then I ran
npx create-react-app projectname
and it worked as expected
I'm trying to start a new React project on my Mac (running Mojave 10.14.5).
In VS Code's Terminal I ran npx create-react-app my-app and got a message saying that my version of Node was out of date. I updated node to version 17.4.0 and ran it again - still got the same message.
I then ran clear cache: npm cache clean --force and tried again - still no luck.
node -v says I'm running 17.4.0.
Would anyone know what I could do?
The first thing you need to do is to uninstall the create-react-app and then npm install it again.
You can use these commands for uninstalling the create-react-app:
if you are using NPM:
npm uninstall -g create-react-app
if you are using Yarn:
yarn global remove create-react-app
for creating new app you can use the following command:
npx create-react-app#latest your-project-name
You must notice that the create-react-app should not be installed globally as it is documented in Create-React-app Docs.
Also please note that it is safe to say, always use the LTS version of node (that is 16.13.2 at this time).
It should solve your problem with initiating a new react app.
I'm starting work on React Native, using create-reactive-native-app and Exponent. There is a nice list of open source examples here, some of then are mentioned to use Exponent.
https://github.com/ReactNativeNews/React-Native-Apps
I have few experience with nodejs. I already noticed there are several possible configurations for React Native apps. I usually use npm start to run it, but that don't work on those examples, since since they don't have a start script in package.json.
Take as an example the native-component-list app. How can I execute it after cloning and doing npm install?
Using node v6.11.4 and npm 3.10.10
I also tried using react-native run-android . It works when I create a new project with react-native init Ola2
But not with the downloaded code.
Here are some more details. I did this before: npm install -g react-native-cli
npm install
react-native run-android
Scanning folders for symlinks in xxx/native-component-list/node_modules (25ms)
Android project not found. Maybe run react-native android first?
react-native android
Scanning folders for symlinks in xxx/native-component-list/node_modules (26ms)
Unrecognized command 'android'
Run react-native --help to see list of all available commands
As per this link, you can run the app with command react-native run-android (for android)
I found the problem. I just had never used Expo.io way to create a ReactNative app. I only knew the init and the crna ways. This apps where created with the exp tool.
So,to run it, just do:
npm install exp --global
npm install
exp android
exp start
I didn't work on Expo, I prefer react-native-cli
In your case, your project in developed on Expo.
So you need expo-cli to run the project.
For Expo Cli
npm install -g expo-cli
For CRNA
npm i -g create-react-native-app
Internally CRNA use EXPO, so you can choose any option. After installing the expo-cli npm start command work fine for you.
Or you can eject this project.
You can run npm run eject to get a project very similar to what react-native init would generate. At that point you’ll need Xcode and/or Android Studio just as you would if you started with react-native init , adding libraries with react-native link will work, and you’ll have full control over the native code compilation process.
Hope it will work for you.
I'm building new React App to learn and play with Draft-js, RichStyle Text Editor.
I used create-react-app to initialize my React application. It's working, and very easy to use.
Now, I tried to add semantic-ui-react, which is React version of SemanticUI lib.
Aaaaannd fail.
npm install semantic-ui-react --save
As you can see, same effect for draft-js.
My issue is that normally there's no problem to use draft-js & semantic-ui-react with React 15.4.2. I use this stack in professional env.
Is there something I'm missing with npm ? Is create-react-app can stop this install ?
Now, I can't install any packages. This error shows up everytime. But, I cant still npm start for my local web server. I also tried npm cache clean
Is my very simple package.json
Thanks again for you help.
Solution : Just update NPM and everything working.
Edit : My App folder :
And my npm & node version
My guess is that you have old npm or node versions, you can't start the project with this versions... you can upgrade npm and node programs.
if you are using brew on OSX then you can use following commands to upgrade them.
brew update
brew upgrade node
npm install -g npm
