ERR_INVALID_ARG_TYPE - “from”参数必须是字符串类型。收到 Array 的实例

Question

我正在尝试为视图文件夹添加两个目录。在文档中，我发现您可以添加字符串或数组以添加多个视图文件夹。

一个用于管理面板，另一个用于网站/公共使用。

所以我按如下方式添加：

/**
 * setting up the view engine
 */
app.engine('handlebars', hbs({
    defaultLayout: "main"
}));
app.set('view engine', 'handlebars');

app.set('views', [path.join(__dirname, 'views'), path.join(__dirname, 'public-views/zubizi-theme')]);
// end view engine setup

我收到以下错误：

TypeError [ERR_INVALID_ARG_TYPE]: The "from" argument must be of type string. Received an instance of Array

这是我的文件夹结构如下：

我在我的应用中使用了以下技术：

NodeJS 模板引擎：express-handlebars。

ExpressJS 版本：4.16.0

Node JS版本：v12.16.3

有一个开放的 PR 支持作为数组传入的多个视图目录：https://github.com/ericf/express-handlebars/pull/209

现在，您需要修复您的设置并将视图合并到一个目录中并仅传递该目录：

app.set('views', './path-to-views-folder');
