同事使用create-react-app创建了一个项目，该项目可在他的计算机上工作。我克隆了，运行npm install，然后启动npm，出现以下失败错误：

有人可以帮忙吗？谢谢
PS：我已尝试删除node_modules并重新运行npm install，uninstall / reinstall node等。
找到了这个线程https://github.com/facebook/create-react-app/issues/9594，这似乎表明重新安装节点可以解决此问题，但对我而言不起作用。
后续行动：使用其他手动步骤完全删除了节点，例如，如此处建议的https://stackabuse.com/how-to-uninstall-node-js-from-mac-osx/，然后重复该过程，然后得到一个错误日志略有不同：
23 verbose stack Error: command failed
23 verbose stack at ChildProcess.<anonymous> (/usr/local/lib/node_modules/npm/node_modules/@npmcli/promise-spawn/index.js:64:27)

23 verbose stack at Process.ChildProcess._handle.onexit (node:internal/child_process:301:5)
经过两天的努力，终于弄清楚了，当前的应用程序是一个子子项目，位于以下路径中：main-project / sub-project1 / src / main / sub-sub-project1。但是从另一个同事的过去工作来看，sub-project1文件夹中有一堆残余节点文件（package.json等），显然我已经在运行“ npm install”并在那里生成了一个node_modules /文件夹，因为它被忽略了，我从来没有意识到这一点。这个node_modules /文件夹是在sub-sub-project1文件夹（其中存在另一个node_modules /）中运行节点命令时引起混乱的原因。
综上所述，不要以这种线性分层方式来处理多个节点项目，这可能会导致节点命令混乱。
