【问题描述】：

我已安装节点版本 14.17.3 LTS 我打开 Visual Studio Code 并在终端中运行 npm init，其中添加了 package.json 文件。然后，我安装了 cypress - npm install cypress --save-dev，它为新版本添加了 devDependencies。在此之后，我尝试打开 cypress runner - npx cypress open 但是它返回了一个错误。

It looks like this is your first time using Cypress: 7.6.0


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.

【问题讨论】：

你可以尝试运行npx cypress open。
对不起，是npx cypress open。我已经在上面更正了。

【解决方案1】：

使用你提到的 npm 步骤，我收到了关于没有 cypress.json 的投诉。

但是纱线似乎很好

纱线初始化
yarn add -D cypress（显示大量子包）
纱柏打开

Cypress 启动并生成文件夹结构、示例文件，并打开运行器。

【讨论】：

我在我的机器上安装了纱线，运行了你提到的所有步骤。但仍然出现同样的错误。
@dwilli 有同样的错误信息并找到了解决办法，见Cypress - Failed to deserialize the V8 snapshot blob
谢谢。这有帮助。我跑了npx cypress install --force，它成功了。
