How to solve the error when compiling a small program in uniapp

What should you do if you use uniapp to develop a small program and an error occurs during the compilation process?

First of all, we need to understand how uniapp compiles small programs. uniapp uses the development specifications of small programs and provides a set of development methods based on vue.js. It will convert vue.js code into applet code when packaging, and generate corresponding applet files.

Next, let’s take a look at the possible errors reported by uniapp when compiling the applet:

The above is the solution to the error reported by uniapp when compiling the applet. Generally speaking, uniapp is mainly developed based on vue.js and requires relevant front-end skills and small program development experience. If you have a certain understanding of front-end and small program development, you should be able to solve problems proficiently when using uniapp.
