如何让npm pack "highcharts-export-server“等待处理完成？

npm pack "highcharts-export-server" && echo "处理完成"

const { exec } = require('child_process');

function packHighchartsExportServer() {
  return new Promise((resolve, reject) => {
    exec('npm pack "highcharts-export-server"', (error, stdout, stderr) => {
      if (error) {
        reject(error);
      } else {
        resolve(stdout);
      }
    });
  });
}

packHighchartsExportServer()
  .then((output) => {
    console.log('处理完成');
  })
  .catch((error) => {
    console.error(error);
  });

const { exec } = require('child_process');

async function packHighchartsExportServer() {
  return new Promise((resolve, reject) => {
    exec('npm pack "highcharts-export-server"', (error, stdout, stderr) => {
      if (error) {
        reject(error);
      } else {
        resolve(stdout);
      }
    });
  });
}

async function main() {
  try {
    await packHighchartsExportServer();
    console.log('处理完成');
  } catch (error) {
    console.error(error);
  }
}

main();
