[webpack-cli] TypeError: Cannot read properties of undefined (reading 'setup')

回答: 如果你在控制台中得到了"Uncaught TypeError: undefined is not a promise"错误，确保你使用的是new Promise()而不是只用Promise()。此外，根据你提供的代码片段，如果你遇到了"TypeError: Cannot read properties of undefined (reading 'setup')"错误，可能是因为你正在尝试读取一个未定义的属性。要解决这个问题，你可以先确保你的对象存在并且具有正确的属性，或者使用可选链运算符(?.)来检查属性是否存在。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
