I was trying to create a new project in cypress and I got the following strange error message.
Steps:
npm init -y
npm install cypress --save-dev
I then did npx open cypress and I got the following message from my console
How do I fix this?
Cypress cannot run because this binary file does not have executable permissions here:
/Users/myName/Library/Caches/Cypress/7.5.0/Cypress.app/Contents/MacOS/Cypress
Reasons this may happen:
- node was installed as 'root' or with 'sudo'
- the cypress npm package as 'root' or with 'sudo'
Please check that you have the appropriate user permissions.
You can also try clearing the cache with 'cypress cache clear' and reinstalling.
----------
Platform: darwin (20.5.0)
Cypress Version: 7.5.0
You can do two things:
Run the command npm cypress cache clear and then again install cypress npm install cypress --save-dev and check.
Or, install npm globally without sudo using the command npm install -g. Then create a new folder and then run npm init, npm install cypress --save-dev and npx cypress open.
Do navigate to the cache directory by doing
cd /Users/myName/Library/Caches/
Here you have to delete Cypress directory completely by running the command
rm -rf Cypress
Now head over to your project directory and run the command
npx install cypress
Cypress will be installed in your system again. Next time you won't get any errors.
So, I had a chat with the dev team at Cypress and got the following answer. After reading the logs I had a feeling this might be the root cause. So please check you have the most up to date version of Node.js

I'm trying to add cypress to the bitbucket pipeline but it tells me that I need to install Xvfb and I don't know how to keep going. This is my bitbucket.pipelines.yml
# Template NodeJS build
# This template allows you to validate your NodeJS code.
# The workflow allows running tests and code linting on the default branch.
image: node:14.15.4
pipelines:
default:
- step:
name: Build
script:
- npm install
- npm run lint
- npm run cypress:run
This is my package.json scripts
"scripts": {
"cypress:open": "cypress open",
"cypress:run": "npx cypress run --record --key xxxxxxxxxxxx"
}
and the test are running fine locally
But in the pipeline I'm getting this error:
+ npm run cypress:run
> wallet-frontend#0.1.0 cypress:run /opt/atlassian/pipelines/agent/build
> npx cypress run --record --key 70004462-62d4-42ce-b359-5bff73d8b001
It looks like this is your first time using Cypress: 6.5.0

Your system is missing the dependency: Xvfb
Install Xvfb and run Cypress again.
Read our documentation on dependencies for more information:
https://on.cypress.io/required-dependencies
If you are using Docker, we provide containers with all required dependencies installed.

Xvfb is an in-memory display server for a UNIX-like operating system, in your case Linux (Debian - 9.13). This is a system-level dependency that cypress assumes is installed beforehand. In the case of bitbucket env, this is not installed and hence this error. This is primarily used for Display (UI) in case of headed browsers while running cypress.
There are few easy workarounds here:
Installing the dependency manually: I won't suggest this as you might miss out few more dependencies unless you thoroughly look into all the dependencies.
Run headless browsers:: Headless browsers don't use Xvfb, so won't be facing this exact error but as I said in point 1, there can be other issues. Command will become cypress run --headless
Use Cypress provided Docker images (Suggested): I can see that you are using the node:14.15.4 image for this build. Instead of that, use a cypress provided official base images for whatever node version you want to run (Look for different node version in tags). If you look into the Dockerfile, you will see that they have taken an effort to install the dependencies needed to run Cypress inside the docker (You can see Xvfb there).
Also, look for already open issues when you get stuck in cypress-related issues, they have a very active and helpful issues section. I found this same issue in there: https://github.com/cypress-io/cypress/issues/14457
Cypress provides the dependencies for CI.

I have installed nodejs with npm, appium guhub package.
My machine does not has Internet connection
How do I use npm to install the appium?
Npm install -g appium
Is not working.
Try with this steps
Create package.json file using npm-init command
list all the modules in package.json that you need
Run npm-install on your terminal

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 want to install latest electron version in my existing angular application.So I followed npm command to install it.
Command : npm i electron#latest
Expected Behavior
Electron should installed successfully.
Actual Behavior
So, Whenever I tried to install electron, after downloading zip file and SAMSUN.txt file , it is throwing below error....
Error: Generated checksum for "electron-v2.0.2-win32-x64.zip" did not match expected checksum.

Please note that I have tried to clear my npm cache using npm cache clean --force command and tried to install. but it didn't work.
I also tried to install electron globally using npm i -g electron#latest, but that approach also didn't work.
Please provide solution as soon as possible because I m really stuck at this problem.
Electron Version: 2.0.2
Operating System : windows
node version : 8.11.2
npm version : 6.1.0
Last known working Electron version:
We can solve this issue by using following steps (OS - Windows 10)
Delete "SHASUMS256.txt-x.x.xx" file from "C:\Users{{UserName}}.electron".
Delete Cache folder from "C:\Users{{UserName}}\AppData\Local\electron".
Delete electron from node_modules folder.
Then install electron globally and locally by using following commands -
npm init -y //Note: The -y flag provides default options automatically
npm install electron -g //install electron globally
npm install electron --save-dev --save-exact //install electron as devdependencies
If you are using typescript then install it as global using below command-
npm install -g typescript
Above steps may help you.
WARN [config]: config.configure() is deprecated, please use config.set() instead.
WARN [plugin]: Cannot find plugin "karma-phantomjs".
Did you forget to install it ?
npm install karma-phantomjs --save-dev
INFO [karma]: Karma v0.10.2 server started at http://localhost:9018/
WARN [launcher]: Can not load "PhantomJS", it is not registered!
Perhaps you are missing some plugin?
Getting this error. When running npm install karma-phantomjs --save-dev I get an error.
npm ERR! 404 'karma-phantomjs' is not in the npm registry.
I installed karma-phantomjs-launcher --save-dev but i still get an error when running grunt watch.
Anyone else run into this issue?
npm install karma-jasmine --save-dev
npm install karma-phantomjs-launcher --save-dev
Then add the following line to karma.config.js
plugins : ['karma-jasmine', 'karma-phantomjs-launcher']
I got tripped up by this today running
karma: 0.13.7
karma-phantomjs-launcher: 1.0.0
What isn't very obvious is that the launcher has a dependency on:
phantomjs-prebuilt
So if you, install this locally everything should run fine, eg:
npm install phantomjs-prebuilt --save-dev
After some research I realized that I needed to run:
npm install -g karma#canary phantomjs karma-phantomjs-launcher
Once I ran that I went back into my karma-unit.tpl.js file and instead of karma-phantomjs, I changed this to karma-phantomjs-launcher.
Now when I execute a command like grunt build, I get no error regarding phantomJS
This is an issue still open on the repo: #31
Strangely enough the following worked for my Debian based system:
apt-get install libfontconfig
How did I get into this? Reading a comment from the ticket. Hope this will help for others too :-)
I'm running in a CentOS 7 Docker container. Had similar issue.
Had to:
yum install -y tar bzip2 freetype fontconfig
Then
npm install phantomjs --save-dev
worked without errors, which allowed
npm install karma-phantomjs-launcher --save-dev
and that allowed
gulp test
to run without Karma or PhantomJS errors.
Today I had the same. I deleted all the temporary directories and, after rerun it worked.
Before that i also reinstalled phantomjs but without success. It's possible that this influenced, anyway (but i think deleting the temporary directories did the job). Anyway, after deleting temporary folders you can try, if it didn't work you can reinstall phantomjs and also other stuff as other users already wrote.
