这是我的打字稿代码:
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { FfmpegCommand } from 'fluent-ffmpeg'
async function bootstrap() {
const app = await NestFactory.create(AppModule);
let test
try {
test = new FfmpegCommand('./adventure.mkv');
} catch (error) {
console.log(error);
}
await app.listen(3000);
}
bootstrap();
生成的Javascript代码:
"use strict";
var __awaiter = (this && this.__awaiter) || function (thisArg, _arguments, P, generator) {
function adopt(value) { return value instanceof P ? value : new P(function (resolve) { resolve(value); }); }
return new (P || (P = Promise))(function (resolve, reject) {
function fulfilled(value) { try { step(generator.next(value)); } catch (e) { reject(e); } }
function rejected(value) { try { step(generator["throw"](value)); } catch (e) { reject(e); } }
function step(result) { result.done ? resolve(result.value) : adopt(result.value).then(fulfilled, rejected); }
step((generator = generator.apply(thisArg, _arguments || [])).next());
});
};
Object.defineProperty(exports, "__esModule", { value: true });
const core_1 = require("@nestjs/core");
const app_module_1 = require("./app.module");
const fluent_ffmpeg_1 = require("fluent-ffmpeg");
function bootstrap() {
return __awaiter(this, void 0, void 0, function* () {
const app = yield core_1.NestFactory.create(app_module_1.AppModule);
let test;
try {
test = new fluent_ffmpeg_1.FfmpegCommand('./adventure.mkv');
}
catch (error) {
console.log(error);
}
yield app.listen(3000);
});
}
bootstrap();
//# sourceMappingURL=main.js.map
当我运行此应用程序时,我遇到下一个错误:
main.ts:12 消息:“ fluent_ffmpeg_1.FfmpegCommand不是构造函数” stack:“ TypeError:fluent_ffmpeg_1.FfmpegCommand不是c:\ nest \ dist \ src \ main.js:20:20 \ n在Generator.next()处的构造函数\ n在完成时(c:\ nest \ dist \ src \ main.js:5:58)\ n在process._tickCallback(内部/进程/next_tick.js:68:7)\n在Function.Module.runMain(内部/模块/cjs/loader.js:834 :11)\ n在启动时(internal / bootstrap / node.js:283:19)\ n在bootstrapNodeJSCore(internal / bootstrap / node.js:622:3)“
这是因为此原始 test = new fluent_ffmpeg_1.FfmpegCommand('./ adventure.mkv')。当我仅通过 test = new fluent_ffmpeg_1('./ adventure.mkv')进行更改时,我没有出现错误。你知道如何解决它。如果您知道打字稿上的ffmpeg示例,请与我分享:)
答案 0 :(得分:0)
这很可能是由于fluent-ffmpeg
导出其组件的方式。
尝试这样导入
import * as FfmpegCommand from 'fluent-ffmpeg
或
import FfmpegCommand from 'fluent-ffmpeg
您还可以安装输入内容,并且在使用模块时会得到帮助
