盡管安裝了文件保護程序，但反應找不到文件保護程序

Question

盡管已安裝 React，但看不到“文件保護程序”。

我讓yarn add file-saver ，然后yarn install仍然沒有。

它的導入方式如下： import { saveAs } from 'file-saver';

在 package.json 看起來像：

"dependencies": {
        "@emotion/is-prop-valid": "^1.1.0",
        "@emotion/react": "^11.4.1",
        "@emotion/styled": "^11.3.0",
        "@material-ui/core": "^4.12.2",
        "@material-ui/icons": "^4.11.2",
        "@mui/lab": "^5.0.0-alpha.48",
        "@mui/material": "^5.0.1",
        "@types/file-saver": "^2.0.3",
        "@types/react-table": "^7.7.2",
        "axios": "0.21.1",
        "core-js": "^3.6.5",
        "date-fns": "^2.24.0",
        "document-register-element": "1.13.1",
        "file-saver": "^2.0.5",

謝謝

Answer 1

嘗試添加“@types/file-saver”：“^2.0.5”，除了“file-saver”：“^2.0.5”
