赛普拉斯无法在 Windows 上启动

Question

I have just installed Cypress using "npm install cypress --save-dev" and got confirmation that the install was successful as detailed below

• Downloaded Cypress
• Unzipped Cypress
• Finished installation

Tried opening Cypress using the prompt: node_modules.bin\\cypress open but got the below message but there was no error listed. Has anyone come across this?

"It looks like this is your first time using Cypress: 1.4.1

→ Cypress Version: 1.4.1 Cypress failed to start.

This is usually caused by a missing library or dependency.

The error below should indicate which dependency is missing.

If you using Docker, we provide containers with all required dependencies installed.

Platform: win32 (10.0.14393) Cypress Version: 1.4.1"

Answer 1

I've had the same issue. After running

npm install --save-dev cypress

you need to run

.\node_modules\.bin\cypress.cmd install

That's a bit confusing in most install guides that I read. After doing this, it worked for me.

Answer 2

试试这个npx cypress install --force然后使用npx cypress open

Answer 3

Try the following, as mentioned here

set NODE_OPTIONS=
cypress run

Answer 4

Add below code of line in package.json file

{
  "scripts": {
    "test": "cypress open"
  }
}

and run cypress thro' editor command prompt using below command prompt

npm run test

Answer 5

看起来您缺少库或依赖项，只需运行： npm install即可安装项目中所需的所有缺少的库和依赖项。

Answer 6

I hope you must have sorted out the issue.

If not, try to delete the cache and rerun cypress. It should work. If you use mac, run below command before running cypress open.

/Users/<username>/Library/Caches/Cypress/

Answer 8

You may have already solved this, however, if not try downloading the binary from download.cypress.io/desktop

Direct download

If you're not using Node.js or npm in your project or you just want to try Cypress out quickly, you can always download Cypress directly from our CDN.

The direct download will always grab the latest available version. Your platform will be detected automatically.

Just manually unzip and double click. Cypress will run without needing to install any dependencies.

.\node_modules\.bin\cypress.cmd install --force
