node-ffi 模块无法加载 32 位 C dll - 动态链接错误

Question

我在尝试使用 nodejs-ffi 模块加载 C 32 位 DLL 时遇到了麻烦。这是我的代码：

运行时，node在Dynanic_library.js上抛出错误：74 Dynamic Linking Error

var ffi = require('ffi');
var ref = require('ref');
var path = require('path');

import idatabase = require('./IDatabase');
import idataset = require('./Dataset');

var dllpath = path.join(__dirname, '../../StoneBaseDLL.dll');
var dbpath = path.join(__dirname, '../../../database/metadata/metadata.db');

export class Stonebase implements idatabase.IDatabase
{
    dbHandler;
    dbConnection;

    constructor() {

        this.dbHandler = ffi.Library(dllpath, {
            'connect': ['void*', ['string']],
            'Execute': ['void*', ['string', 'void*']],
            'disconnect': ['void*', ['void*']],
            'EndOfResultSet': ['bool', ['void*']],
            'Next': ['void', ['void*']],
            'getNumberOfFields': ['int', ['void*']],
            'GetField_AsString': ['string', ['int', 'void*']],
            'GetField_AsChar': ['string', ['int', 'void*']],
        });

        this.dbConnection = this.dbHandler.connect(dbpath);
    }

    execute(query: string) {
        var data: Array<Array<string>>;
        var columns: Array<string>;
        data = [];
        columns = [];
        var i = 0;

        var dset = this.dbHandler.Execute(query, this.dbConnection);

        for (var j = 0; j < this.dbHandler.getNumberOfFields(dset); j++) {
            columns[j] = "column" + j;
        }

        while (!this.dbHandler.EndOfResultSet(dset)) {
            var line: Array<string>;
            line = [];
            for (var j = 0; j < this.dbHandler.getNumberOfFields(dset); j++) {
                line[j] = (<string>this.dbHandler.GetField_AsChar(j, dset));
            }
            data[i] = line;

            this.dbHandler.Next(dset);
            i++;
        }

        return new idataset.Dataset(data, columns);
    }

}

我正在使用 Typescript，但我很确定这与问题无关

谢谢大家的帮助！

您是否检查过您的节点是 32 位的？如果您的节点是 64 位，则切换到 32 位并重试。
