您是否收到类似以下内容的错误消息？

\n

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

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 命令来解决问题。这里有一个案例你可以参考一下。

另外， 的引号\xe2\x80\x9c$(Agent.OS)\xe2\x80\x9d应该是这样的"$(Agent.OS)"。或者，您可以选择在自托管代理中运行作业，机器级缓存和配置在每次运行中都会保留，这可以提高速度。
