Question

大家好，我是azure devops CI的新手，我正在尝试通过在作业之间缓存node_modules来减少管道构建时间，但是我遇到了无法解决的错误。我正在使用赛普拉斯进行测试。这是我的蔚蓝管道

是否收到类似于以下内容的错误消息？

The cypress npm package is installed, but the Cypress binary is missing.
We expected the binary to be installed here: /xxx/.cache/Cypress/4.8.0/Cypress/Cypress
Reasons it may be missing:
- You're caching 'node_modules' but are not caching this path: /xxx/.cache/Cypress
- You ran 'npm install' at an earlier build step but did not persist: /root/.cache/Cypress
Properly caching the binary will fix this error and avoid downloading and unzipping Cypress.
Alternatively, you can run 'cypress install' to download the binary again.

如果是这样，根据错误日志，它提供了解决此问题的方法。您可以尝试再次运行cypress install命令来解决该问题。这是您可以参考的case。

此外，“$(Agent.OS)”的引号应类似于"$(Agent.OS)"。或者，您可以选择在self-hosted代理中运行作业，机器级别的缓存和配置会在每次运行时保持不变，这可以提高速度。
