找不到模块：无法解析“@date-io/date-fns”

Question

我正在使用 React Material UI，但出现此错误：找不到模块：无法解析“@date-io/date-fns”。

这是我的 package.json 文件中的依赖项：

"dependencies": {
    "@date-io/date-fns": "^2.0.0",
    "@material-ui/core": "^4.9.5",
    "@material-ui/pickers": "^3.2.10",
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "axios": "^0.19.2",
    "date-fns": "^2.0.0",
    "react": "^16.13.0",
    "react-dom": "^16.13.0",
    "react-facebook-login": "^4.1.1",
    "react-google-login": "^5.1.14",
    "react-google-maps": "^9.4.5",
    "react-hook-form": "^5.2.0",
    "react-router": "^5.1.2",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.4.0"
  },

我试过安装date-io/date-fns的最后一个版本，然后又试了2.0.0版和1.0.0版，我仍然得到同样的错误。

Answer 1

$ npm i date-fns@next @date-io/date-fns@1.x
参考：
https://github.com/mui-org/material-ui-pickers/issues/240
https://github.com/dmtrKovalenko/date-io/issues/33

参考：https://material-ui-pickers.dev/getting-started/installation#peer-library

Important: For material-ui-pickers v3 use v1.x version of @date-io adapters.

npm i @date-io/date-fns@1.x date-fns
// or
npm i @date-io/moment@1.x moment
// or
npm i -s @date-io/luxon@1.x luxon
// or
npm i -s @date-io/dayjs@1.x dayjs

你可以查看这个命令...

yarn add date-fns

or

npm i date-fns

Answer 3

在我的代码中，我使用了 "import DateFnsUtils from "@date-io/date-fns/build/date-fns-utils"，这导致了 "Module not found: Error: Can't resolve '@date-io/date-fns/build/date-fns-utils' ..." 异常。

我已经通过从@date-io/date-fns'导入来解决这个问题。

import DateFnsUtils from '@date-io/date-fns';

找不到模块：无法解析“@date-io/date-fns”

Module not found: Can't resolve '@date-io/date-fns'

reactjs

material-ui
