npm 安裝：反應腳本安裝失敗

Question

我有以下（簡化的）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"
  ]
}`

當我嘗試使用npm install它時，安裝它失敗了幾次（首先是一些關於不推薦使用的依賴項的警告，最后是幾個 npm ERR.代碼（見下文），我試圖刪除 node_modules 文件夾，嘗試npm cache clear --force , 他們都沒有幫助. 這是 npm 安裝的 output ：

任何想法我做錯了什么？

謝謝！

因此，Dropbox 同步似乎是有罪的，它在npm install期間鎖定了 npm 不喜歡的東西。 我將文件夾從我的保管箱文件夾中移出，然后......驚喜，驚喜......就像魅力一樣。

現在的任務是找到一種解決方案，從同步中選擇性地排除子文件夾（dropbox 不支持類似.gitignore 的解決方案），但這與 javascript 或 node 或 npm 無關...
