引入npm的int32库报错

npm install int32
把int32 file-uri-to-path 和 bindings 3个库拷贝到项目中
报错如下:
bindings.js:29 Uncaught TypeError: Cannot read property 'modules' of undefined
at Object.<anonymous> (bindings.js:29)
at Object.../../../../../../Users/YJY/Documents/Code/UniApp/XXX/bindings/bindings.js

如果引入使用另一个库npm install int64的话
报错如下:
index.js:113 Uncaught TypeError: Cannot read property 'substring' of undefined
at Object.<anonymous> (index.js:113)
at Object.../../../../../../Users/YJY/Documents/Code/UniApp/XXX/int64/index.js (index.js:10254)

咋整？
