噩梦不用等待下载

Question

我正在尝试使用噩梦下载一些代码 但是代码不会等待，也不会下载文件

async function ProblemDownload(Name, Categ, Lang, ProblemLink){
    //console.log(ProblemLink);
    await nightmare.on('download', async (state, downloadItem) => {
        if(state == 'started'){
            await nightmare
            .emit('download', '.\\CODES\\'+CATEG_WHERE[Categ]+'\\'+Name+LANGUAGES_EXTEND[Lang], downloadItem)
            .then((data) =>{
                console.log(data)
            })
            .catch( () => {})
            //'+CATEG_WHERE[Categ]+'\\'+Name+LANGUAGES_EXTEND[Lang]
        }
        else if(state == 'completed'){
            console.log(downloadItem);
        }
    })
    .catch()
    return await nightmare
    .downloadManager()
    .goto(ProblemLink)
    .waitDownloadsComplete()
    .then(() =>{
        console.log('nome: ', Name)
    })
    .catch(() => {});
}

这是我在运行代码时得到的反馈，该代码始终在下载代码，而不下载预期的其他两个代码。

有人可以帮我解释一下我如何让《噩梦》在每次下载前都等待下载。
