Question

我是javascript新手，如果这是一个愚蠢的问题，请对不起。我试图运行Firebase部署，但最终出现此错误消息

  1:1  error  Parsing error: Unexpected character '�'

✖ 1 problem (1 error, 0 warnings)

npm ERR! code ELIFECYCLE

Error: functions predeploy error: Command terminated with non-zero exit code1

我的index.js看起来像这样

const functions = require('firebase-functions');
// replaces keywords with emoji in the "text" key of messages
// pushed to /messages
exports.emojify =
    functions.database.ref('/messages/{pushId}/text')
    .onWrite(event => {
        // Database write events include new, modified, or deleted
        // database nodes. All three types of events at the specific
        // database path trigger this cloud function.
        // For this function we only want to emojify new database nodes,
        // so we'll first check to exit out of the function early if
        // this isn't a new message.

        // !event.data.val() is a deleted event
        // event.data.previous.val() is a modified event
        if (!event.data.val() || event.data.previous.val()) {
            console.log("not a new write event");
            return;
        }

        // Now we begin the emoji transformation
        console.log("emojifying!");

        // Get the value from the 'text' key of the message
        const originalText = event.data.val();
        const emojifiedText = emojifyText(originalText);

        // Return a JavaScript Promise to update the database node
        return event.data.ref.set(emojifiedText);
    });

// Returns text with keywords replaced by emoji
// Replacing with the regular expression /.../ig does a case-insensitive
// search (i flag) for all occurrences (g flag) in the string
function emojifyText(text) {
    var emojifiedText = text;
    emojifiedText = emojifiedText.replace(/\blol\b/ig, ":D");
    emojifiedText = emojifiedText.replace(/\bcat\b/ig, ":D(cat)");
    return emojifiedText;
}

代码是从一个教程（已有2年历史）复制粘贴的，所以我不知道这可能是错的。

文件开头看起来像 UTF-8 BOM 。

如果您有notepad ++，则可以通过单击“编码”->“转换为不带BOM的UTF-8”将其删除：
