问题描述
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。
所以我以以下方式添加：
/**
* 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
我遇到以下错误：
TypeError [ERR_INVALID_ARG_TYPE]: The "from" argument must be of type string. Received an instance of Array
(node:108) UnhandledPromiseRejectionWarning: 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，如下所示：
。
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
解决方法
有一个开放的PR，用于支持以数组形式传入的多个视图导演：https://github.com/ericf/express-handlebars/pull/209
现在，您需要修复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');
