Javascript 分析错误：Firebase云函数中出现意外的令牌selectWinner-Node.js V10

我无法部署我的云函数，因为我遇到了一个解析错误：意外的令牌selectWinner

我已经更新了.eslintrc.json中的解析器选项，以使用ecmaVersion 2017，但这不起作用。在进行更改后，我重新启动了文本编辑器atom，但也没有起作用

exports.updatePollWinner = functions.firestore.document('updatePollWinner/{id}').onCreate(trigger => {
  const week = trigger.get('week');
  return db.collection("polls").where("sport", "==", 1).where("week", "==", week).where("pollType", "==", "WDIS").get()
  .then((querySnapshot) => {
    await selectWinner(querySnapshot)
  });

});

async function selectWinner(querySnapshot) {
  const scoringTags = ["STD", "0.25PPR", "0.5PPR", "PPR", "0.10PPC", "0.25PPC", "0.5PPC", "4PTPASS", "5PTPASS", "6PTPASS", "-2INT", "TEPREMIUM"];
  let winningChoiceIds = [];
  let totalPollIds = [];
  for (const doc of querySnapshot) {
    await processWinner(doc)
  }
  admin.firestore().doc('triggerAccuracyCalculation/'+Date.now().toString()).set({
    winningChoiceIds: winningChoiceIds,
    totalPollIds: totalPollIds,
    week: week
  });
}

async function processWinner(doc) {
  totalPollIds.push(doc.id);
  let pollData = doc.data();
  let tags = pollData.tags.filter(tag => scoringTags.includes(tag.code)).map(tag => tag.code);
  let winner = {score: 0, choice: {}, choiceId: null};
  for (const choice of pollData.choices) {
    await processChoice(choice)
  }
  winningChoiceIds.push(winner.choiceId);
  const pollDoc = db.doc(`polls/${doc.id}`);
  pollDoc.update({winner: winner});
}

async function processChoice(choice) {
    let choiceId = choice.id
    let mappedChoices = choice.players.map(player => {
      return { displayName: player.displayName, playerId: player.playerId, position: player.position, team: player.team }
    });

    // ToDo: What happens if someone posts a poll with two players in one option? This poll should be ignoree from accuracy calculation
    // ignmore if option has more than one player
    // if (mappedChoices.length > 1) return;

    const player = mappedChoices[0]

    // We can't score defense
    if (player.position === "DEF") {
      return;
    }

    const playerId = player.playerId;
    // Make FFN API call to retrieve stats for that player in that weekconst statsEndpoint = `https://www.fantasyfootballnerd.com/service/player/json/${functions.config().ffnerd.key}${req.url}`;

    const statsEndpoint = `https://www.fantasyfootballnerd.com/service/player/json/${functions.config().ffnerd.key}/${playerId}`;
    const json = {"Stats": {"2019": ""}, "Player": {}};
    https.get(statsEndpoint, (resp) => {
      let data = '';

      resp.on('data', (chunk) => {
        data += chunk;
      });

      resp.on('end', () => {
        const weekString = week.toString();
        const fetchedStats = JSON.parse(data).Stats
        if (!fetchedStats) return;
        const response = fetchedStats["2019"]
        if (!response) return;
        // TODO SCORE KICKERS AND DEFENSES
        const stats = response[weekString];
        let score = 0;

        // Additional bonus for TE premium leagues
        if (player.position === "TE" && tags.includes("TEPREMIUM")) {
          stats["receptions"] ? score += parseInt(stats["receptions"]) / 2 : false
        }

        // Do stuff no matter what your position is
        stats["recYards"] ? score += parseInt(stats["recYards"]) / 10 : false
        stats["recTD"] ? score += parseInt(stats["recTD"]) * 6 : false
        stats["rushYards"] ? score += parseInt(stats["rushYards"]) / 10 : false
        stats["rushTD"] ? score += parseInt(stats["rushTD"]) * 6 : false
        stats["xpMade"] ? score += parseInt(stats["xpMade"]) : false
        stats["fgMade"] ? score += parseInt(stats["fgMade"]) * 3 : false
        stats["kickoffRet"] ? score += parseInt(stats["kickoffRet"]) / 10 : false
        stats["SackYards"] ? score -= parseInt(stats["SackYards"]) / 10 : false
        stats["fumbleLost"] ? score -= parseInt(stats["fumbleLost"]) * 2 : false

        // Determine winner
        // ToDo: handle ties
        if (score > winner.score) {
          winner.score = score;
          winner.choiceId = choiceId;
          winner.choice = choice;
        }
      });
    }).on("error", (err) => {
      console.log("Error: ", err.message);
    });
}

这些函数应该同步处理，但由于此错误，我无法调用第一个函数

您正在未标记为async的函数中使用await。那是无效的

.then((querySnapshot) => {
  await selectWinner(querySnapshot)
});

你是说这个吗

.then((querySnapshot) => {
  return selectWinner(querySnapshot)
});

或者，更好的方法是一致地使用async/await：

exports.updatePollWinner =
functions.firestore.document('updatePollWinner/{id}').onCreate(async (trigger) => {
  const week = trigger.get('week');
  const querySnapshot = await db.collection("polls").where("sport", "==", 1).where("week", "==", week).where("pollType", "==", "WDIS").get()
  await selectWinner(querySnapshot);
});

可能是问题吗？我正在使用节点10，所以不确定是否需要执行这些操作？我刚刚更新了这个问题，将指定节点版本的package.json和eslintrc.json包含在内
