So I'm opening my the existing React Native project. This is the procedure on how I opened my existing React Native project. 1st step, type the location of my project which is in the "D:\rnprojects\firstproject\". 2nd step, "react-native-start". 3rd step, I opened another cmd then locate it again into my project directory then typed "npm start".
Why when I created this project I didn't get this error just when runnning/opening my existing project.
This the error that I got: (with versions)
There is only simple steps can solve your particular scenario issue quickly.
1) Install the React native cli in your project or globally.
npm install -g react-native-cli
OR
npm install react-native --save
then start your project by using this command
npm start
If any dependencies issue please follow the second solution
2) Please make sure you're installed all dependence
yarn install
OR
npm install
under your project directory
I'm pretty sure your issue will fix by using 1st solution Thanks.
it is simple:
1.npm install
2.react-native run-android
Here I guess you have the RN environment to run already on your side.
- cd path_to_project
install packages(there are two following ways to install packages).
2.1 yarn install
2.2 npm install
react-native link(optional - you need to run this command if existing project use RN packages which need to link such as react-native-vector-icons)optional(if project use pods) cd ios pod install
react-native run-ios or react-native run-android according to the platform which you want to run on.
I don't think above is perfect instruction give you how to run the existing react-native project, But I am pleasure if give me some hints or help to you.
You can find official guide here
Sometimes npm's cache gets confused and need to reset it by using below command:
npm cache clean --force
Also try below command:
npm install --save-dev react-native-cli
Hope it will help you.
