Today, I created a new small program project in wechat developer tool
but when I opened it, such a bug appeared
which made me feel very confused

Unhandled promise rejection TypeError: WebAssembly Instantiation: Argument 0 must be a buffer source or a WebAssembly.Module object

It was very uncomfortable
I went to the wechat developer community and asked
it turned out that the default version of the basic debugging library was too high, which led to an error

A simple solution

Click the details button in the upper right corner
and select local settings
to adjust the basic debugging library back to 2.14.4
