I can't start any CRNA project because it gets stuck at "Starting packager", I tried many projects but the problem still remains.
It always gets stuck at "Starting packager..."
I'm using react-native#0.46.4 and expo#19.0.1 on ubuntu 16.04
PS: I even tried a blank project and starter projects so I think the problem is with CRNA itself.
Note
npm shows me an unmet dependency error with expo and react:
npm ERR! peer dep missing: react#>=15.3.1, required by lottie-react-native#1.1.1
npm ERR! peer dep missing: react#>=15.4.0, required by react-native-branch#2.0.0-beta.3
I tried these solutions but the problem remains: https://github.com/react-community/create-react-native-app/issues/203
The problem was fixed by running:
sudo sysctl -w fs.inotify.max_user_watches=10000
Run this command before running npm start or yarnpkg start

I'm trying to install expo globally on my Windows 10 machine for a school assignement.
As the doc says, I've been trying the following command in my terminal :
$ npm install --global expo-cli
but it always gives me the same error :
npm ERR! Cannot read property 'matches' of undefined
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\User\AppData\Local\npm-cache\_logs\2021-04-07T13_43_16_562Z-debug.log
I've tried running $ npm install -g expo-cli instead but the same thing happens.
I haven't tried reinstalling node or anything yet because I need my pc up and running for this week and I'm not too accustomed to all that, I'd like to keep that a last resort if possible.
Has anyone ever encountered this error before ?
Thanks to those who replied but I "accidentally" fixed it myself.
Through my searching I ended up actually uninstalling node with $ nvm uninstall v15.0.0 and I found myself obligated to download it again here.
Must've been a problem with the version I was using as suggested before.
Try removing the node_modules folder and package-lock.json file and run command npm 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 use a MacOS High Sierra. For anyone with experience with Nuxt.js, the command
npx create-nuxt-app <project-name> has not worked for me at all!
I consistently come across errors from npm saying I need to update my dependencies. I first tried updating each dependency using npm outdated (check for outdated packages) and
npm update <pkg name>. This did not work.
I also uninstalled and reinstalled node and npm and tired the above (and below processes). Still did not work.
No matter what I do, the Terminal keeps saying my core-js needed to be updated so I did that (I tried both npm i core-js and npm i core-js ) - they did not work.
To update the npm dependencies, I used the command npm install -g npm-check-updates followed by ncu -u, and then tried both npm update and npm install. Nothing has worked so far.
Lastly, I've tried creating a package.json since npm complained that I had no package.json so I created one using npm init and following the instructions to commit the file(s) created. Still, nothing after running npx create-nuxt-app <project-name>.
What is happening? Has anyone experienced this issue? I really love Nuxt.js and I've tried this for an entire day but I'm giving up on using NuxtJS.
EDIT: I managed to solve part of my problem by creating a Nuxt app from scratch. However, I get the following errors:
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! nuxt-app#2.11.0 dev:nuxt
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the nuxt-app#2.11.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
There are many solution based on your problem. Sharing a simple one, if you have npm installed then execute below command to install npx:
npm install -g npx
you can find all others solution from here
and My suggestions are:
As i saw your description, package.json not created. definitely something wrong for creation of the project, it may cause the read write problem of files into disk. or you have created the project into subdirectory but trying to run the project from parent directory. initially many peoples doing this practice to create scratch project. by the way create a separate directory and then run npx create-nuxt-app. no need to give project name and pass the phase when prompt to create project in same directory. so then i think problem will solved
I fixed the issue! It worked when I created a new directory altogether (the next day) and reran npx create-nuxt-app <new-app>. Get started, build for production, and tests ran perfectly.
I followed the tutorial in the link here https://facebook.github.io/react-native/docs/getting-started.html#content . As it turns out, npm 5 is not supported yet. I tried installing npm 4 but, it is not working either. Stuck in the first page of the tutorial, when I run npm start, I am getting a bunch of errors too. Literally stuck, nowhere else to turn. Before voting down the question, kindly note that I am a mobile developer working with andorid and Ios having no previous knowledge about web technologies. Thanks
These are the steps I followed
npm install -g create-react-native-app
It was successfull, then,
create-react-native-app AwesomeProject
for this line, I got the following error
*******************************************************************************
ERROR: npm 5 is not supported yet
*******************************************************************************
It looks like you're using npm 5 which was recently released.
Create React Native App doesn't work with npm 5 yet, unfortunately. We
recommend using npm 4 or yarn until some bugs are resolved.
You can follow the known issues with npm 5 at:
https://github.com/npm/npm/issues/16991
*******************************************************************************
Then I ran the command
cd AwesomeProject
Afterwards I ran
npm start
for which I got the error
npm ERR! missing script: start
npm ERR! A complete log of this run can be found in:
npm ERR! /home/jayakrishnan/.npm/_logs/2017-07-25T08_13_06_277Z-debug.log
I tried using Yarn But didnt work
npm i -g npm#4.6.1 - then install create-react-native-app again and create a project.
Solution with Yarn:
First install Yarn
yarn global add create-react-native-app
cd AwesomeProject
yarn start
npm install -g npm#4 Use this to downgrade, Also use sudo with the commands, sometime it does give permission to write error and skips the installation
Try putting more information about the error so we can help, or steps to reproduce it.
One thing to try is to instead of using npm, use yarn. Install yarn with brew install yarn if you are on mac and do the same steps in the getting-started guide, except for use yarn run ios to start app in ios simulator.
I just tried with a fresh setup that this is working perfectly fine.
Reference to yarn https://yarnpkg.com/en/
I'm getting npm ERR! invalid errors when I try npm ls or npm install, and it seems like npm is incorrectly thinking peers have incompatible versions. A good example (I get several of these at a time):
npm WARN unmet dependency /MYLOCALPROJECTDIRECTORY/node_modules/grunt-contrib-imagemin/node_modules/imagemin/node_modules/imagemin-gifsicle requires image-type#'^0.1.1' but will load
npm WARN unmet dependency /MYLOCALPROJECTDIRECTORY/node_modules/grunt-contrib-imagemin/node_modules/imagemin/node_modules/image-type,
npm WARN unmet dependency which is version 0.1.4
According to the rules of semver, the caret "^" operator should match a requirement of ^0.1.1 with an actual dependency of version 0.1.4 just fine.
I've installed Node v0.10.30 with npm v1.4.23 using Homebrew (both the latest stables), running OS X Mountain Lion. I'd appreciate tips on finding how to reliably reproduce this - last time I totally uninstalled/reinstalled Node and npm, same local npm modules and everything, and could not find the error again. Came back to work the next day, tried to install some grunt plugin, and ran into all these errors again.
If you happen to reproduce it, I bet you can solve it by removing the node_modules folder, cleaning the cache and reinstalling:
rm -rf ./node_modules
npm cache clean
npm install
I know this is not an actual answer, but I guess it's better than uninstalling/reinstalling node/npm.
