Javascript npm安装：react脚本安装失败

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"
  ]
}`

操作系统：Win10 home，64位 节点：v13.1.0 净现值：6.12.1

知道我做错了什么吗

谢谢

看来，Dropbox synch是罪魁祸首，它在npm安装期间锁定了npm不喜欢的东西。 我把文件夹从dropbox文件夹移到了外面，然后。。。惊喜，惊喜。。。工作很有魅力

现在的任务是找到一个有选择地从同步中排除子文件夹的解决方案（dropbox不支持类似.gitignore的解决方案），但这与javascript、node或npm无关…

基本上，如果node抛出lock、rename、delete错误，这意味着它试图重命名由于某种原因被OS锁定的资源。我在.npmrc文件中使用了缓存和前缀选项，它解决了许多节点的重命名和删除问题。添加两个名为“prefix”和“cache”的条目，其值应为当前文件夹节点模块文件夹之外的有效文件夹路径。我的指向

cache=“c:\\workspace\\temp\\npm cache”prefix=“c:\\workspace\\npm”

的要点感谢您的提示，虽然它并没有解决我的问题，但给了我一个解决方案的思路。。。见下文。。。
