微信小程序不支持直接读取node_modules

首先在目录文件夹下cmd输入npm init命令

D:\小程序\project\calendar\calendar_1>npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.See `npm help init` for definitive documentation on these fields
and exactly what they do.Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.Press ^C at any time to quit.

}Is this OK? (yes)D:\小程序\project\calendar\calendar_1>npm installremoved 181 packages in 2mD:\小程序\project\calendar\calendar_1>

以上为cmd下操作过程，基本一路enter即可。

最后removed 181 packages in 2m是应为之前在calendar_1下就有node_modules。

然后到微信开发者工具下：

构建完成：

会生成如下文件夹：
