我正在尝试在我的react.js应用程序中使用@field。该应用程序是从 Themeforest 购买的主题。我面临的错误是这样的

ERROR in ./src/watermelon/model/Staff.js Module build failed (from ./node_modules/babel-loader/lib/index.js): SyntaxError: C:\projects\siloc-react-laravel\siloc-react\src\watermelon\model\Staff.js: Support for the experimental syntax 'decorators' isn't currently enabled (8:3): 6 | 7 | > 8 | @field('name') name; | ^ 9 | // @action async getStaff() 10 | // { 11 | // return { Add @babel/plugin-proposal-decorators (https://github.com/babel/babel/tree/main/packages/babel-plugin-proposal-decorators) to the 'plugins' section of your Babel config to enable transformation.

我使用的文件是这个 Staff.js

import { Model } from '@nozbe/watermelondb'; import { field } from '@nozbe/watermelondb/decorators'; export default class Staff extends Model { static table = 'staff'; @field('name') name; // @action async getStaff() // { // return { // id: this.id, // name: this.name // } // } }

我在互联网上看到的解决方案是在 .babelrc 中添加这些行。但就我而言,这些似乎是在 package.json 文件中完成的配置,因为我没有 .babelrc 文件

"plugins": [ [ "@babel/plugin-proposal-decorators", { "legacy": true } ], [ "@babel/plugin-proposal-class-properties", { "loose": true } ], [ "@babel/plugin-transform-runtime", { "helpers": true, "regenerator": true } ] ]

这是我的整个 package.json 文件

Try this: Install customize-cra through the package manager, then create the config-overrides.js file in the root directory where package.json is located and put the following code in it:

const { addBabelPlugins, override } = require("customize-cra"); module.exports = override( ...addBabelPlugins( [ "@babel/plugin-proposal-decorators", { "legacy": true } ] ) );

And remove babel configuration from package.json. You can move your configuration into config-overrides.js as suggested by customize-cra documentation. (https://github.com/arackaf/customize-cra/blob /HEAD/api.md)
