Question

我有一个 Node/Angular 项目，由于这个错误而无法运行。我收到以下错误：

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

该错误的更多上下文：

PS C:\Users\Vinay\retail-billpay-node> node server
internal/validators.js:124
    throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
    ^

}

如果有帮助，这是我的 package.json：

好的，我找到了问题所在。我以为错误告诉我路径未定义。事实上，它说传递给 path.join() 的变量是未定义的。那是因为我忘记将我的 .env 文件添加到根目录，以便它可以获取这些变量。

由于这是一个企业项目，所以他们不会在源代码中保留 .env 文件，我问他们并将其放在根目录中。

NodeJS - TypeError [ERR_INVALID_ARG_TYPE]：“路径”参数必须是字符串类型。收到未定义（mkdirp 模块 nodejs）
