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.
have downloaded latest version of node.js on mac
terminal says ive downloaded latest version of expo cli
if i try to run my first project in terminal; expo init project name, am always met with the same error. -bash: expo: command not found.
when i check terminal to make sure that expo is installed, i am also met with: -bash: expo: command not found.
i have spent at least 3 days trying to resolve this problem.
any help towards this resolution would be greatly appreciated
How have you downloaded the Expo CLI? It may be important to note that if you don't install the package globally, like npm install -g expo-cli, it may not be properly executable.
[Additionally, One thing I've found when installing commands is that it can help to restart your terminal. Sometimes after you've installed something new, not everything will be in place, but it might be there when the terminal restarts.]
I am trying to get rid of the following error message.
patch-package 6.2.2
Applying patches...
Error: Patch file found for package mongodb-query-parser which is not present at node_modules/mongodb-query-parser
This message appears when I try to install mongo-express. Locally this is no problem, because npm install keeps progressing after the error message.
But when I try to run it on gitlab-pipeline it exits the job.
Is there any workaround?
Temporary quick fix is to install mongo-express without the postinstall.
npm install mongo-express --ignore-scripts && npm install
That way the patch-package isn't called and at least the CI doesn't break. But I'm not sure how unsecure this is...
Hopefully going to be fix soon! I opened an issue

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
C:\ProjectName> react-native install
Scanning folders for symlinks in C:\ProjectName\node_modules (794ms)
error: missing required argument `packageName'
I ran the command above and recieve the error shortly afterwards. I am not very sure what the problem is I am new to react-native and was just trying to ran an already developed project. I hope someone can help shed some light regarding this.
You are missing the package manager.
If you are using yarn:
yarn add react-native
or npm:
npm install react-native
You can read more here:

EDIT: Also, don't forget to install react-native-cli
