Cypress - 无法反序列化 V8 快照 blob

Question

首次尝试在 Visual Studio 代码中运行 Cypress 时，我收到以下输出：

It looks like this is your first time using Cypress: 6.4.0

  ×  Verifying Cypress can run C:\Users\username\AppData\Local\Cypress\Cache\6.4.0\Cypress
    ? Cypress Version: 6.4.0
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.

#
Fatal error in , line 0
Failed to deserialize the V8 snapshot blob. This can mean that the snapshot blob file is corrupted or missing.

如何解决这个问题，以便赛普拉斯运行并执行应用程序的测试？

Answer 1

您还可以修剪缓存，因为这是许多版本的已知问题。

./node_modules/.bin/cypress cache clear

然后运行

./node_modules/.bin/cypress install --force

这对我有用。

Windows（我的例子中是 10 个）用户请注意：要运行上面的命令，您必须允许在终端上发布控制台脚本执行策略。为此，Set-ExecutionPolicy RemoteSigned -Scope Process终端必须以管理员权限运行。

我在这个GitHub 问题中找到了适用于我的案例的解决方案

解决方案是重命名 Cypress 缓存，然后从应用程序目录重新安装 Cypress。

On Windows, the Cypress cache is in \AppData\Local\Cypress\Cache

npm install cypress
