Can't run "npm install expo-cli --global" - react-native

Question

I am a newbie in all this stuff. Hope for your understanding.
Let me clarify the issue:
I am trying to start react native app through expo cli. So tried to start npm install expo-cli --global to install npm globally. I got these errors:
Screen_1
Screen_2
It also says that I lack permissions to access it. How can I allow permissions?
Even when I try to start it locally I got the same issue. Your help is appreciated.

Answer 1

although this solution is not the best and the safest solution exists, this worked for me and that make sense because all the problem we had with the errors is the permission problems. so you can use this command and ignore those permission problems :
sudo npm install expo-cli -g --unsafe-perm

Answer 2

I was having the same problem with npm install -g expo-cli, having "MODULE_NOT_FOUND",
I installed yarm with brew, just in case you do not already have it:
brew install yarn
and then use:
yarn global add expo-cli
to create a project you can:
expo init nameOfTheNewProject
and choose a template in the console.
Finally run the project with
yarn start
Let me know if it works for you!

Answer 3

You did not mention which os. This answer working for any operating system (ubuntu in my case)
I'm also getting permission errors when running
sudo npm install --global expo-cli
Which I don't really how this can happen - as this also happens for the superuser!
For me it works when I install the client locally into the project
cd <new-project-dir>
npm init # init npm project
npm install expo-cli
Now you can use the client in this project like this:
npx expo-cli # e.g. npx expo-cli init <project-name>

Answer 4

npm cache clean --force
This will solve the issue

Answer 5

Try using npm install -g expo-cli#3.5.0 this worked for me, it may work for you.

Answer 6

You can try this command:
npm install -g expo-cli
or,
yarn global add expo-cli

Answer 7

You have to run the command as administrator from a command prompt on windows and not bash. Had me stumpt for bloody ages!

Answer 8

You need administrator privilege. So when you open command line interface, just right click and run as administrator
This will solve the problem

Answer 9

I guess, this issue comes from permission or node version , if you get this error when the node module is being refreshed ---> This is definitely a permission issue. Disable your Antiviruses or change permission manually check this as well.

Answer 13

It is likely you do not have the permissions to access this file as the current user.
The best way to solve this problem is to reinstall npm with a node version manager.And you don't need to remove your current version.
About node version manager
use nvm or n with OSX or Linux
use nodist or nvm-windows with windows

Answer 14

Upgrade Node version to +10
Then do
sudo npm install expo-cli -g

Answer 15

This worked for me. I hope this would solve your problem!
sudo npm install expo-cli -g --unsafe-perm=true --allow-root

try going into windows resource monitor and terminating adb.exe (android resource bridge). This worked for me after searching for solutions for days. I tried this after verifying cache, clearing cache, you name it.

As a Debian 10 buster user I got the same permission error while using this command: sudo npm install expo-cli --global.
The problem was solved by installing expo-cli with yarn package manager and the command below: sudo yarn global add expo-cli.

Answer 22

For Windows User :-
Open your Powershell and type:
npm install expo-cli --global
This worked for me after trying and reasearching for hours.
Note:Don't Use cmd or any other terminal and also don't type npm install expo-cli -g as it is written in the react native docs. It would always show up an npm error.

Answer 23

For windows
Follow these steps carefully
open the command prompt and run it as administrator.
recommended npm uninstall --global expo-cli.
run the command npm cache clean --force.
run the command npm cache verify .
now run the command npm install --global expo-cli
dont run command like npm i -g expo-cli or npm install -g expo-cli.
7.Make sure you run the command mentioned in the 4th step ONLY.
thankyou.
