我正在使用Cypress代码覆盖率和instrument-cra插件。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。我已经验证了/root/app/.nyc_output 存在并包含覆盖率数据。
我已经在赛普拉斯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

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：这是未找到的 nyc 命令。在 Cypress 调用之前添加 'env PATH="$PATH：./node_modules/.bin" 可以解决问题。我真的必须使用它还是有更好的方法？
编辑2：更好的解决方法是使用自动将路径设置为node_modules/.bin的npx cypress run。也许这是真正的解决方案？
根据我在上面问题中的EDIT 2将$(npm bin)/cypress run替换为npx cypress run。
我无法判断这是否真的是正确的解决方案，或者它是否是某些事情的解决方法。
