npm安装：react-scripts安装失败

Question

我有以下（简化的）package.json文件：

`{
  "name": "cotd",
  "version": "0.0.3",
  "private": true,
  "dependencies": {},
  "devDependencies": {
    "react-scripts": "3.2.0"
  },
  "scripts": {
    "dev": "react-scripts start",
    "start": "react-scripts start"
  },
  "browserslist": [
    ">0.2%",
    "not ie <= 11",
    "not op_mini all"
  ]
}`

[当我尝试使用npm install安装它时，它几次失败了（首先是有关已过时依赖项的警告，最后是几个npm ERR！代码（请参见下文）。我试图删除node_modules文件夹，尝试了npm cache clear --force，但都无济于事。这是npm install的输出：

任何想法我在做什么错？

谢谢！

因此，似乎Dropbox同步是有罪的，它在npm install期间锁定了npm不喜欢的东西。我将文件夹从我的保管箱文件夹移到了外面，然后……出乎意料，出乎意料……就像魅力一样。

现在的任务是找到一种解决方案，以选择性地从同步中排除子文件夹（dropbox不支持类似.gitignore的解决方案，但这与javascript或node或npm无关。
