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.

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'm trying to add a create-react-app app inside a Turborepo monorepo.
Problem is that if I run npm install from the root of the monorepo and then try to start the CRA app by running npm run dev, I get the following error during compile time:
Loading PostCSS "postcss-preset-env" plugin failed: Cannot find module 'postcss-preset-env'
I noticed that if I run npm install from within the CRA app folder (/apps/my-app), and then run npm run dev from the root of the monorepo, it runs just fine.
I also noted that depending from where I run npm install, the contents of /apps/my-app/node_modules will be different, but I think is the expected behaviour.
If I understand correctly the npm workspaces docs, you should always run npm install from the root of the monorepo.
Any idea on what I'm missing here?
I'm using npm 8.3.1.
Here is a public repo with an example: https://github.com/oncet/turborepo-cra
I recently tried to launch my project on a new computer. I downloaded the source code from its repository and ran npm install to get all the needed packages.
However, when I run npm start or expo start:web, I get the error:
Cannot find module '#expo/metro-config'
I ran npm install #expo/metro-config and the install run without issue, but I still get the “Cannot find module '#expo/metro-config'” error.
The only post I saw regarding this error recommends editing the metro.config.js but I do not use one.
I am on SDK 42, and the project launches fine on my other computer. Any idea what is happening?
FYI, I use to perform this whole operation without any issue until now.
UPDATE:
I ran npm install -g #expo/metro-config and now I get the error Cannot find module 'resolve-from'
So it looks like maybe running npm install -g expo-cli doesn't actually install all the necessary packages? Could it be the issue?
I managed to make it "work" (get other missing packages errors down the line) by reverting to expo-cli 4.7.3. Anything from 4.8.0 and above will cause the error.
Something else is that on a fresh npm install, after running npm install -g expo-cli, if I try to create a project with expo init, I will get the error Error: Cannot find module 'kleur'. Running npm install kleur fix it, but maybe that's also a clue.
I am trying to follow this link to use detox for e2e testing for my react native app. I did it successfully once, but I removed e2e folder, was conducting some experiments, now I am not able to run detox init -r jest
every time I run this line it gives me this error:
Error: "detox-cli" package is not meant to be installed locally, exiting...
HINT: Remove the local installation and reinstall it globally:
npm uninstall detox-cli
npm install -g detox-cli
I have tried the solution in the hint, but it didn't resolve the issue, any suggestions?
If I uninstall and run the command, same error shows up.
when I install it, this is what I see (node version and detox-cli version)
/Users/.../.nvm/versions/node/v14.17.0/bin/detox -> /Users/.../.nvm/versions/node/v14.17.0/lib/node_modules/detox-cli/cli.js
+ detox-cli#18.13.0
updated 1 package in 1.358s
-----Update:
I just tried this and worked:
/Users/.../.nvm/versions/node/v14.17.0/bin/detox init -r jest
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
