Question

我已经在我的 Windows 10 机器上安装了 Cypress。
在 VSCode 终端窗口中的项目文件夹中，我首先运行 npm init -y 然后我运行以下命令 npm install cypress --force 然后我运行命令 npx cypress open 我收到以下错误

PS C:\Projects\Cypress Projects\QACypressDemo> npm install cypress --force
npm WARN using --force Recommended protections disabled.
npm WARN deprecated har-validator@5.1.5: this library is no longer supported

PS C:\Projects\Cypress Projects\QACypressDemo> npx cypress open
It looks like this is your first time using Cypress: 7.3.0

  ×  Verifying Cypress can run C:\Users\Usera\AppData\Local\Cypress\Cache\7.3.0\Cypress
    → Cypress Version: 7.3.0
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 are using Docker, we provide containers with all required dependencies installed.

Platform: win32 (10.0.16299)
Cypress Version: 7.3.0

我尝试从中删除 Cypress 文件夹并再次运行安装命令。赛普拉斯仍然无法运行 C:\Users\Usera\AppData\Local\cypress

不知道为什么 Cypress 不会运行，测试运行器不会打开。有任何想法吗。谢谢。

Answer 1

当安装中途中断时，我遇到过这样的问题。您可以clear the cache 并重新安装它。我使用了以下顺序：

cypress cache clear
npm install cypress --save-dev

Answer 2

npm install 和 npx cypress 在两个不同的位置运行二进制文件。如果要使用安装到目录中的二进制文件，则需要运行在节点模块文件夹中找到的二进制文件。在 Windows 上，如果您运行 ./node_modules/.bin/cypress，应该会在您的节点模块文件夹中启动该版本。
