我试图加载.dll在简单的js文件，以下官方文档here。
如果我尝试从官方文件，它的工作

var ffi = require('ffi-napi');

var libm = ffi.Library('libm', {
  'ceil': [ 'double', [ 'double' ] ]
});
libm.ceil(1.5); // 2

// You can also access just functions in the current process by passing a null
var current = ffi.Library(null, {
  'atoi': [ 'int', [ 'string' ] ]
});
console.log(current.atoi('1234')); // 1234

字符串
但是，如果我尝试加载与dll.js文件在同一个文件夹中的.dll-代码如下所示

const ffi = require('ffi-napi');
const path = require('path');

const file = path.join(__dirname, '/testLibrary');

const pos = ffi.Library(file, {
  testFunction: ['void', ['int']],
});

我得到这个错误：

我对自动添加到那里的.dylib扩展名感到困惑。
我试图添加.dll扩展名，但在日志中我可以看到/Users/martin/Projects/serialPortTest/testLibrary.dll.dylib。
我尽可能地用谷歌搜索它，但没有任何帮助。
任何帮助都很感激。
