I'm generating a new project using React-Native in Command Prompt but I get an error when I use the following command:
react-native init Style
This is the result I get:

How can I fix this error?
Mustafa AK had it right. What worked for me is adding the --npm flag at the end of the command.
I followed the tutorial exactly how it was laid out on the React website and was running into the same error. For whatever reason, if you have yarn and npm installed the command to create a new project will not work. So you have to add the --npm flag to get it to only use npm and this will work.
npx react-native init AwesomeProject --npm
This Same error comes with me. But I solved by following ways...
First, uninstall the node from your system and download the latest version of node and install it.
2.after installation of the latest version of node you need to write the command in your command prompt
npm install -g react-native-cli
Now go to your project directory
cd your-react-native-project directory
now create your react-native project
react-native init your-project-name.

Be sure uninstall global react-native/cli as described react-native tutorials
Try to use --npm end of init command if you had yarn and npm both.
npx react-native init MyApp --template react-native-template-typescript --npm
Note: If you have both yarn and npm installed on your machine, React Native CLI will always try to use yarn, so even if you use npx utility, only react-native executable will be installed using npm and the rest of the work will be delegated to yarn. You can force usage of npm adding --npm flag to the command.

I have tried removing and reinstalling the following
sudo npm uninstall -g react-native-cli #react-native-community/cli
Nodejs
The problem has been fixed by updating the system to 13.2.1
Then execute
sudo npm uninstall -g react-native-cli #react-native-community/cli
npx react-native init AwesomeProject --npm
In the Terminal I get the following error after running the expo build:android command:
Error: Can't find react-native in package.json dependencies
Error: react-native is not installed. Please run `npm install` or `yarn` in your project directory.
There is an error with your project. See above logs for information.Error: There is an error with your project. See above logs for information.
Terminal error picture
I have already tried to update npm version, npm install, and I also tried npm install -g eas-cli
Are there certain steps anyone thinks I should do?
Follow below guide
Delete node_modules folder in root folder
npm install (If you are using yarn use yarn install)
I am using react native and Expo. I am unable to build new app because after I use expo init appName it shows the following error.
Heres the full message:
📦 Using npm to install packages. You can pass --yarn to use Yarn instead.
√ Downloaded and extracted project files.
× Something when wrong installing JavaScript dependencies. Check your npm logs. Continuing to initialize the app.
✅ Your project is ready!
To run your project, navigate to the directory and run one of the following npm commands.
- cd Scanner
- npm start # you can open iOS, Android, or web from here, or run them directly with the commands below.
- npm run android
- npm run ios # requires an iOS device or macOS for access to an iOS simulator
- npm run web
I tried multiple times to create a blank project, also tried npm install to install failed/not downloaded libraries and continue after failure but it showed another error:
npm ERR! code Z_BUF_ERROR
npm ERR! errno -5
npm ERR! zlib: unexpected end of file
also tried npm cache verify that showed cache is ok Content verified: 3562 (252580364 bytes).
So, How can I solve this issue?
Problems related to npm installation are very common If you do any mistake in early installation, but is avoided. Learn more about npm tree.
Steps worked for me are :
npm cache clean --force
npm cache verify
npm -g uninstall expo-cli --save
npm install expo-cli --global
expo init app-name
cd app-name
npm start
Always run as administrator if working on Windows and in root directory.
The solutions above didn't work for me but if you use 'npm install' in the directory of the app you get a clue that you shuold try 'npm install --force'
err message
You should have all these files folders and files at the start of the project otherwise not all the dependencies have been installed which is why we were getting the problem.folder structure
After you have added --force to npm install you have all the dependencies installed. Now you can run the app with npm start.
Unfortunately, all the solutions described above didn't work on my machine...
Here is my latest solution for this problem...
This worked 100% on my machine...
Use npm i -g expo-cli
This will automatically add the required packages and also remove the unnecessary ones.
Yes, surely, you don't need to uninstall and re-install it again.
Just follow my steps.
And, you can create your expo project using expo init.
I hope my solution will help you out from this annoying problem....
I just did npm install and it worked for me, but I had do that every time I create a new expo project.
I also encountered this problem, and finally found that it was the problem of react native cli，I installed the latest version of react native cli，Expo is back to normal
This Error is regarding to the git account. expos need a git account to setup react native project
If you are using windows you need to install git in your local PC
after that open your Terminal and type this command
git config --global user.name "your_username"
git config --global user.email "your_email_address#example.com"
after that clone any github project to your local computer. it will ask to login to Github
after all these steps try expo init <projectname>
The simple way to settle that error is by using "expo-cli init app-name" instead of "expo init app-name".
I tried and worked perfectly for me. Hope it will help you guys.
i have faced a similar problem and running yarn set version 1.22.1 fix it
Run the Command Prompt as an administrator. And run the following command:
npx create-expo-app AwesomeProject
I'm trying to build a project in expo react native project.
My expo version is 3.2.2, sdkVersion is 35.
When I ran in cmd (on Windows 10)

expo build:android -c
I got:

I'm tried to update expo version, sdkVersion, the version in react, check for internet connection.
Expo login and logout works fine. I don't have any proxy in my network.
I don't have any clues for what search or how to fix this problem.
Seems was a error in expo-cli version 3.2.2.
The update 3.2.3 fixed for me.
I have fixed the issue by using this command
Move to your root folder then type this command in your terminal
npm install -g expo-cli
I had two versions of expo-cli installed (one via yarn global install expo-cli and one as a dev dependency in project yarn add -D expo-cli). This started working for me after I removed the global expo-cli:
yarn global remove expo-cli
and used the local version in my project instead:
yarn run expo-cli start
Run those following command, then we are good to go.
$ yarn global remove expo-cli && yarn global add expo-cli
$ rm -rf node_modules/ yarn.lock && yarn install
$ yarn run start
I am very new to React-native and I have a sample project when I tried running the command react-native run-android. I got an error command not found.
in the current directory do
react-native -v
you will get the following
react-native -v
react-native-cli: version
react-native: version
if it shows command not found the n you have not installed react native in the directory. Do a npm init in new folder and try installing a new react native project there
by doing npm install -g react-native-cli
Follow the steps to add path variable react-native.
You're good to go.
Have you run 'npm install' (without parameters) in the project directory? That'll install the dependencies for your project.
Details here: https://docs.npmjs.com/cli/v6/commands/npm-install
1.Try to install globally npm install -g react-native-cli 2.add path of npm module (C:\Users\your user name\AppData\Roaming\npm) to system variables instead of user variables
