node程序打包成.exe,为什么无法脱离node独立运行，.exe必须和node_modules放在同级目录并且电脑要有node环境才能运行，如何解决？
我需要将3d-tiles-tools增加批处理功能，并且将装个项目打包成.exe，双击.exe要运行optimizeB3dm.cjs（代码如下）
//optimizeB3dm.cjs
// import { spawn } from 'child_process';
// import fs from 'fs';
// import path from 'path';
// import async from 'async';
const { spawn } = require('child_process');
const fs = require('fs');
const path = require('path');
const async = require('async');
// 获取当前执行目录，即虚拟文件系统根目录
const baseDir = path.dirname(process.execPath);
// 输入和输出目录
const rootDir = path.join(baseDir, 'specs/MyData');
const outputDir = path.join(baseDir, 'output');
// 如果输出根目录不存在，则创建它
if (!fs.existsSync(outputDir)) {
fs.mkdirSync(outputDir, { recursive: true });
}
// 创建一个限制并发执行数量的队列
const queue = async.queue((fileData, callback) => {
const { inputFilePath, outputFilePath, isJson } = fileData;
if (isJson) {
// 如果是 JSON 文件，直接复制
fs.copyFile(inputFilePath, outputFilePath, (err) => {
if (err) {
console.error(`复制 JSON 文件失败 ${inputFilePath}: ${err.message}`);
} else {
console.log(`复制成功 ${inputFilePath}`);
}
callback();
});
} else {
// 如果不是 JSON 文件，则执行压缩
const command = path.join(baseDir, 'node_modules/.bin/3d-tiles-tools');
const args = [
'optimizeB3dm',
'-i', path.resolve(inputFilePath),
'-o', path.resolve(outputFilePath),
'--options',
'--draco.compressMeshes',
'--draco.compressionLevel=10'
];
const proc = spawn(command, args, { shell: true });
let dracoError = false;
proc.stdout.on('data', (data) => {
console.log(`stdout: ${data}`);
});
proc.stderr.on('data', (data) => {
const errorMessage = data.toString();
console.error(`stderr: ${errorMessage}`);
if (errorMessage.includes("Draco encoding failed")) {
dracoError = true;
}
});
proc.on('error', (err) => {
console.error(`Error processing ${inputFilePath}: ${err.message}`);
callback(err);
});
proc.on('close', (code) => {
if (dracoError) {
console.log(`文件 ${inputFilePath} 不可被压缩。`);
} else if (code !== 0) {
console.error(`压缩失败 ${inputFilePath}`);
} else {
console.log(`压缩成功 ${inputFilePath}`);
}
callback();
});
}
}, 5); // 并发处理 5 个文件
// 递归遍历目录
function processDirectory(directory) {
fs.readdir(directory, (err, files) => {
if (err) throw err;
files.forEach(file => {
const fullPath = path.join(directory, file);
fs.stat(fullPath, (err, stats) => {
if (err) throw err;
if (stats.isDirectory()) {
// 递归处理子目录
processDirectory(fullPath);
} else {
const inputFilePath = fullPath;
const relativePath = path.relative(rootDir, fullPath);
const outputFilePath = path.join(outputDir, relativePath);
// 确保输出目录存在
const outputFileDir = path.dirname(outputFilePath);
if (!fs.existsSync(outputFileDir)) {
fs.mkdirSync(outputFileDir, { recursive: true });
}
if (path.extname(file) === '.json') {
// 如果是 .json 文件，直接复制
queue.push({ inputFilePath, outputFilePath, isJson: true });
} else if (path.extname(file) === '.b3dm') {
// 如果是 .b3dm 文件，添加到队列进行压缩
queue.push({ inputFilePath, outputFilePath, isJson: false });
}
}
});
});
});
}
// 开始处理
processDirectory(rootDir);
// 当队列中的任务完成时，打印完成消息
queue.drain(() => {
console.log('全部文件处理完毕');
});

接着我进行打包
pkg . --targets node18-win-x64 --output 3d-tiles-tools.exe --assets 'node_modules/**/*'
