I don't understand why my npm make that and i'm new with react-native.
Here is the description of my "bug" on Windows 10 :
I can use react-native command for run android or create react-native app like that react-native init TestApp
When i go into my app folder with cd TestApp and i run react-native link or other react-native command everythings work fine.
But if i install a new package like fbsdk with npm like that npm install react-native-fbsdk --save i saw after installation this message :
added 1 package and removed 639 packages in 22.207s
And after that, if i would like use react-native command i have this message :
Command link unrecognized. Make sure that you have run npm install and that you are inside a react-native project.
For this message, i have entered react-native link command.
You know why npm remove all my packages ?
I got the same problem.
However I solved the problem by deleting the package-lock.json and then running npm install.
Check the answer here.
I also noticed recently that npm install doesn't do what I expect, but that may be because I'm newbie.
However yarn install is a good replacement and is working fine for me. I used it to upgrade/downgrade things by directly editing packages.json, and it also solved the npm link problem that I faced.
Edit: downgrading to npm 7 solved all my issues

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
nodejs version 14.17.5
vue native version 0.3.0
I am developing an application that requires navigation in APP.
When i give command "npm run start" the application successfully runs.
Package.json dependencies installed:
enter image description here
For navigation when i run command "npm install view-native-router" it shows the error message as below:

Does anybody have the idea what could possibly have gone wrong? Is it a compatibility issue ?
It seems this is not the first time we have a peer dependency problem here and the last issue was marked as solved.
https://github.com/GeekyAnts/vue-native-router/issues/45
Since you have a higher version of vue-native-core in local, try add --legacy-peer-deps to npm install to see if works.
Though --force or --legacy-peer-deps may work for some but not everyone.
My solution is to start using yarn! Install it by the following:
$ npm i -g yarn
After its installed, its advised that you delete the project and redo the vue-native-cli init command so it can use yarn from there, but you can also just directly use the following command without deleting the project:
$ yarn install vue-native-scripts
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 having trouble with my node.js/npm setup,
I freshly installed it via the website and it worked fine.
It told me to make sure /usr/local/bin/npm has to be in my path and when I run
echo $PATH it is in there, so it should be fine.
I can now install packages (tested with npm i webpack -save-dev) the installation works as expected, without any errors.
But when i run webpack all It is giving back is command not found has anyone experienced
something like this before?
I believe what you are looking for is a global package install.
Try using
npm i -g webpack
You can get help on install with
npm help i
Did you install node v8/npm v5?
In that case, it seems there's an open big-bug ticket on the npm repository.
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
