Question

尝试在我的电子反应应用程序中要求tfjs-node时出现此错误。我没有安装React之前没有发生过此问题，我认为这是由于webpack中的某些内容需要配置。

const tf = require('@tensorflow/tfjs-node');

错误日志：

我是webpack的新手，非常感谢您的帮助，也很乐意回答需要进行的任何澄清，因为我不知道问题的具体来源。

问题在于需求。 “ @ tensorflow / tfjs-node”导出多个（可能），因此此模块内的导出类似于

module.exports = {
    firstThing,
    secondThing, ...
}

因此，代码中的tf是对象，而不是函数。因此，您应该使用这样的命名导入，

const {tf} = require('@tensorflow/tfjs-node')

因此，调用tf时出现错误。我没有使用此程序包，但这似乎是导致错误的原因。如果仍不能解决问题，请添加引发错误的行。

TypeError：“原始”参数必须为Function
