我正在使用赛普拉斯代码覆盖和仪器 cra插件。当在我自己的机器上本地运行时，这工作得很好，但是当通过 CircleCI 运行时，我得到：

CypressError: cy.task('coverageReport') failed with the following error:
> Error: Command failed with ENOENT: nyc report --report-dir ./coverage --temp-dir /root/app/.nyc_output --reporter=lcov --reporter=clover --reporter=json
spawn nyc ENOENT

目前尚不清楚它抱怨的是哪个文件。我已经验证 /root/app/.nyc_output 存在并包含覆盖数据。

我在 Cypress 中启用了调试日志记录并得到：

code-coverage parsed sent coverage +0ms
code-coverage created folder /root/app/.nyc_output for output coverage +1ms
code-coverage wrote coverage file /root/app/.nyc_output/out.json +17ms
cypress:server:plugins:child execute plugin event: task ({ eventId: 2, invocationId: 'inv11' }) +100ms
code-coverage saving coverage report using command: "nyc report --report-dir ./coverage --temp-dir /root/app/.nyc_output --reporter=lcov --reporter=clover --reporter=json" +68ms
code-coverage current working directory is /root/app +0ms

完整的运行可在https://circleci.com/gh/magjac/graphviz-visual-editor/114获得

我已按照本指南进行设置。

这是我的 CircleCI config.yaml（有很多可怕的调试和解决方法）：

编辑：找不到的是 nyc 命令。在 Cypress 调用之前添加 `env PATH="$PATH:./node_modules/.bin" 可以解决问题。我真的必须使用它还是有更好的方法？

编辑 2：更好的解决方法是使用npx cypress run自动设置 node_modules/.bin 的路径。也许这是真正的解决方案？

根据上面问题中的我的EDIT 2替换$(npm bin)/cypress run为。npx cypress run

我无法判断这是否真的是正确的解决方案，或者它是否是某种解决方法。
