I'm seeing an error when attempting to install the latest cypress on my Windows 10 machine. I was using cypress 8.7 just fine. I deleted node_modules and package-lock.json and removed "cypress": "^8.7.0", from package.json.
Now installing cypress (9.1) I see this error:
npm install --save-dev cypress
npm ERR! Error: Cannot find module 'har-validator'
I see the same error when trying to use the old version too
npm install --save-dev cypress#8.7.0
System info from powershell:
node -v
> v16.8.0
npm -v
> 7.21.0
UPDATE:
My friend is able to install with dependency 8.7.0 in package.json, on OSX with nodejs 14.16.0.
This works today (2021-11-26) for me
npm install --save-dev cypress#8.7.0
There is a Bug in #cypress/request.
Take a look at https://github.com/cypress-io/request/pull/15
EDIT: There is a PR from one of the devs. https://github.com/cypress-io/request/pull/16
Looks like Cypress issue with latest versions. we have this problem for v8.7.0 today. "npm install har-validator" manually installed the missing har-validator module, that helped.
For some reasons I can't update or remove my version of Expo-cli.
I'm stuck on the 3.11.7 version. When I launch the update, it ends correctly but without being taken into account.
I've tested all the methods I've found but I haven't been able to uninstall it yet.
When I launch my project, it continues to launch normally with the v.3.11.7.
here are the commands line i already try :
yarn global remove expo-cli
npm -g uninstall expo-cli --save
sudo apt-get --purge remove expo-cli
yarn uninstall expo-cli
the expo --version commands is not working anymore ...
I need help please.
screenShot of the update request:
Please confirm OS. Mine is Windows 10.
Look in appdata for yarn or npm install directories. You can find the globally installed package files and delete expo.
Essentially an npm or yarn version other than the one you're using has installed the expo-cli and now your current version can't find it.
I solved this by deleting the expo files in that dir
Had the same problem. Here's how I decided it ( Win 10 )
Open cmd as administrator and type npm cache verify
After that type npm -g uninstall expo-cli --save, if it freezing terminate it.
Remove from your user folder ".expo" folder.
Than try npm -g uninstall expo-cli --save in cmd, if it freezing terminate it and open some expo project.
type yarn remove global expo-cli and then yarn add global expo-cli in the project
Hope it helps somebody else too.
My system already has webpack version 4.27.5, but I need to uninstall this version and then use an older version 4.19.1, instead. I'm using Ubuntu.
I've run the command:
npm uninstall <web package>
but my issue was not resolved.
I recommend you to create a .npmrc file and add it
save-exact=true
This will prevent you from get packages like "^4.19.1", which AFAIK this means, get any package above 4.19.1
and then just install the needed package using the following command
npm install webpack#4.19.1 --save-dev
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.
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
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!
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>
npm cache clean --force
This will solve the issue
Try using npm install -g expo-cli#3.5.0 this worked for me, it may work for you.
You can try this command:
npm install -g expo-cli
or,
yarn global add expo-cli
You have to run the command as administrator from a command prompt on windows and not bash. Had me stumpt for bloody ages!
You need administrator privilege. So when you open command line interface, just right click and run as administrator
This will solve the problem
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.
First run npm cache verify, then run sudo npm install --global expo-cli.
Did work for me indeed after trying so much.
Follow the steps
First, run npm cache verify.
Open Windows PowerShell as administrator and run npm install expo-cli
--global --no-optional command.
npm cache clean --force then npm install --unsafe-perm -g expo-cli
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
Upgrade Node version to +10
Then do
sudo npm install expo-cli -g
This worked for me. I hope this would solve your problem!
sudo npm install expo-cli -g --unsafe-perm=true --allow-root
If any of the solutions above result in success, please follow the steps below:
Uninstall Node.js
Restart your pc/mac
Download latest version of the Node.js (https://nodejs.org/en/)
Open cmd as admin mode or use "sudo" before the command line on Mac.
npm install expo-cli --global
I hope it can help
In my case, I deleted two files then everything worked. The two files are in this path: C:\Users\{Username}\AppData\Roaming\npm under the names 'expo.ps1' and 'expo-cli.ps1'
Then run:
npm i -g expo-cli
re-install node.js, it works for me
First update Node.js to the latest stable version and then again try to install expo ad clean before expo folders that are being created in below location
C:\Users\{{computer_username}}\AppData\Roaming\npm
If it's throwing error in visual studio code, try from cmd, was facing same error but solved through this way
npm install -g expo-cli
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.
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.
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.
I had this problem in Windows 10, to be able to install the latest version (I had no choice since it broke the current one). I had to install the latest version of Python (3.8.0) and then run npm install --global --production windows-build-tools as an administrator, then I was able to run again: npm install expo-cli --global to install the version 3.8.0 of the expo-cli
Here is the solution and 100% working. I am working with Windows and not sure abut Linux.
Open cmd and
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
then press yes
Now run the command to start your project
npm install -g expo-cli
I had previously removed Expo from my Windows machine and encountered this error whilst trying to reinstall. Reading the error message solved the problem.
npm i expo-cli -g --legacy-peer-deps
Using this command in 'PowerShell' installed expo successfully.
If anyone else has this problem here is my fix, go to Finder, in the input field (search box) type in /usr/local/lib then press CMD + SHIFT + G press the OK button or whatever pops up, then CMD + SHIFT + . and delete the NVM file i deleted the expo folder too. Then go to this link https://changelog.com/posts/install-node-js-with-homebrew-on-os-x
follow the instructions and install brew, node, etc. Last step go to your terminal and type sudo npm install expo-cli --global
First: I upgraded my mac version 10.13 to 10.15
Then I downloaded homebrew, Watchman, Git and Node.js
Finally I ran this command sudo npm install --global expo-cli --legacy-peer-deps
If you have any further questions check the docs out: https://docs.expo.dev/get-started/installation/
Sometime, I use npm not work.
I try a lots times run with npm but fail for expo cli.
Please try yarn global add expo-cli
It wills save your time ^^.
I was trying to install expo-cli with my company npm registry configured.
I've created 2 differents profiles using npmrc and using the profile with https://registry.npmjs.org/ solved the issue.
