I'm going to upgrade react-native but before I do, I need to know which version I'm upgrading from to see if there are any special notes about upgrading from my version.
How do I find the version of react-native I have installed on my Mac?

To see what version you have on your Mac(Window also can run that code.), run react-native -v
and you should get something like this:
If you want to know what version your project is running, look in /node_modules/react-native/package.json
and look for the version
key:
The best practice for checking the react native environment information.
react-native info
which will give the information
React Native Environment Info:
System:
OS: Linux 4.15 Ubuntu 18.04.1 LTS (Bionic Beaver)
CPU: (8) x64 Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
Memory: 2.08 GB / 7.67 GB
Shell: 4.4.19 - /bin/bash
Binaries:
Node: 8.10.0 - /usr/bin/node
Yarn: 1.12.3 - /usr/bin/yarn
npm: 3.5.2 - /usr/bin/npm
npmPackages:
react: 16.4.1 => 16.4.1
react-native: 0.56.0 => 0.56.0
npmGlobalPackages:
react-native-cli: 2.0.1
react-native: 0.57.8
You can also open your package.json
file in node_modules
-> react-native
.
The version is at the top:
{
"name": "react-native",
"version": "0.12.0",
...
}
If you want to see
which version of react-native
, react
or another one you are running, open your terminal
or cmd
and run
the desired command
npm view react-native version
0.63.4
npm view react version
17.0.1
npm view react-scripts version
4.0.1
npm view react-dom version
17.0.1
this works for me
npm view react-native version
Output is: 0.63.4
npm view react version
17.0.1
npm view react-scripts version
4.0.1
npm view react-dom version
17.0.1`
Move to the root of your App then execute the following command,
react-native -v
In my case, it is something like below,
MacBook-Pro:~ admin$ cd projects/
MacBook-Pro:projects admin$ cd ReactNative/
MacBook-Pro:ReactNative admin$ cd src/
MacBook-Pro:src admin$ cd Apps/
MacBook-Pro:Apps admin$ cd CabBookingApp/
MacBook-Pro:CabBookingApp admin$ ls
MyComponents __tests__ app.json index.android.js
ios package.json
MyStyles android img index.ios.js
node_modules
Finally,
MacBook-Pro:CabBookingApp admin$ react-native -v
react-native-cli: 2.0.1
react-native: 0.44.0
To see the local packages installed in your project including their versions and without their dependencies, run the below command from the project's root directory. In a React native app this would include the react-native package.
npm list --depth 0
Or if you installed them with yarn:
yarn list --depth=0
And to get just a specific package:
npm list react-native --depth 0
yarn list --pattern react-native --depth=0
Find out which react-native is installed globally:
npm ls react-native -g
If you are using npx
you can run:
npx npm view react-native version
If you have installed "react-native" globally then just open terminal/command line tool and type react-native -v
you will get your answer.
And if you have installed "react-native" for a specific project then open terminal/command line tool and then navigate to your project and type react-native -v
you will get your answer.
I know 2 ways to test react-native version
First, make sure npm is installed on your system.
Use: [sudo] npm install npm -g
to download and install it.
If you installed react native globally, on your terminal type:
react-native --version
But if you installed without the global flag -g, type:
npx react-native --version
Or
yarn react-native --version
(If you have yarn installed)
Just Do a "npm audit" on your project directory and then go to your project package.json file. In the package.json file you will find all the versions and the package names.This should work irrespective of the OS.
Check your Package.json file to know react-native version.
OR
Open terminal and run command react-native -v
react-native Usage: bin [options]
Options: --version Print CLI version --verbose Increase logging verbosity -h, --help output usage information react-native --version use this command
If you have installed "react-native"
globally then just open your terminal and use react-native -v
to get the version installed on your pc.
Just open the below file in your project :-
package.json
under dependencies
object you will get the version of react-native
To see what version you have on your Mac terminal, run react-native --version and you should get something like this:
To know the react native version, just type the command.
npx react-native --version
Another option for checking react-native version with npx is :
npx react-native info
