ERR_INVALID_ARG_TYPE - "from" 参数必须是字符串类型。接收到一个数组实例

ERR_INVALID_ARG_TYPE - The "from" argument must be of type string. Received an instance of Array

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 website/public 使用。

所以我通过以下方式添加:

/**
 * 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:

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

节点 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您的视图合并到一个目录中并仅传递该目录:

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