ReactJS npm 運行構建引發 elifecycle 和導出錯誤(奇怪)

[英]ReactJS npm run build throws elifecycle & export errors (weird)

我正在嘗試通過npm run build (創建生產構建)構建一個 React 項目

  • 我可以使用npm start就好了,它編譯反應代碼並在瀏覽器上完美運行

npm run build - error npm 運行構建錯誤

這很奇怪,因為最初我只收到 ELIFECYCLE 錯誤,然后我嘗試清除 npm-cache 並刪除 node_modules 目錄和 package-lock.json 以重新安裝所有內容。

npm cache clean --force
delete node_modules folder
delete package-lock.json file
npm install

elifecycle 錯誤stackoverflow 帖子

現在我已經這樣做了, npm start命令仍然可以編譯並運行反應前端就好了,但是當我嘗試構建它時,我也收到了這個導出錯誤,這很奇怪,因為這不是問題

CheckBoard.js 組件:

...
import { checkBoard } from './validation/checker_validation'
//import checker_validation from './validation/checker_validation'
//import { checker_validation } from './validation/checker_validation'
import { tokenChars } from 'ws/lib/validation'
import { parse } from 'uuid'
export default class CheckerBoard extends Component {
    state = {
        gameBoard: this.props.gameData,
        boardInv : this.props.boardInv,
        dispOverlay : {},
        selectedPawn : null,
        selectedValid : []
    }

    //Overlay Initializer:

    //Whenever a pawn is clicked, this function executes:
        //This function executes the validation algorithm, then generates an overlay of all possible moves the user can make

    pawnClick = async (e) => {
        const coord1D = parseInt((e.target.id).split('-')[1]);

        await this.setState({dispOverlay: {'selectedPawn' : coord1D} });

        const newGame = [...(this.state.gameBoard.map((e)=> {return parseInt(e)}))]

        console.log('PAWN CLICK DEBUG:');
        console.log('Game Board:');
        console.log(newGame);
        console.log('Coord 1D');
        console.log(coord1D);

        let valid = this.state.boardInv ? checkBoard(newGame.reverse(),63-coord1D) : checkBoard(newGame, coord1D);

        if(this.state.boardInv){
            valid = [...valid.map((e) => {return e.map( (j) => {return -1*j} )  })];
        }

        this.setState({
            selectedValid : valid
        })

        console.log('Validated: '+JSON.stringify(valid))

        const reducerSum = (pV, cV) => pV + cV;

        for(let v of valid){
            let entry = this.state.dispOverlay;
            
            if(Math.abs(v[0]) < 14){
                entry[parseInt(coord1D)+parseInt(v)] = false; //false is move, true is kill
            } else {

                for(let [i,e] of v.entries()){

                    const killEntry = parseInt(coord1D)+v.slice(0,i+1).reduce(reducerSum,0);
                    entry[killEntry] = true

                }




                //Returns the possible positions of selected Pawn (for every possibility)

                //entry[parseInt(coord1D)+parseInt(v)] = true;
            }
            this.setState({dispOverlay : entry});
        }
    }
...

checker_validation.js

const checkBoard = (board, pawnCoord, justKilled) => {
  ...algorithm that returns something...

    if(!foundKill){
        return [[]];
    }

    return res;
}


// console.log(checkBoard(gameboard,42))

module.exports = {
    checkBoard
} 
//exported here

我無法弄清楚為什么 react run build 表現得如此奇怪,即使在我完全重新初始化 npm 並且導出顯然適用於開發構建和工作之后,我不知道構建的問題是什么。

Package-lock.json: Github -> Frontend/package-lock.json (它很長,所以我不能復制/粘貼到這里)

感謝shidoro我解決了這個問題,我改變了

module.exports = {
    checkBoard
} 

以 ES6 方式:

export{ checkBoard }

它編譯(帶有警告,但這是由於缺乏錯誤處理)
