Closed. This question is off-topic。它当前不接受答案。
想改善这个问题吗? Update the question,所以它是on-topic,用于堆栈溢出。
4年前关闭。
我宁愿发布图像而不是代码本身来更好地展示问题,这些是文件的最后几行:
很明显,我的代码以第237行结尾。但是,当我从终端输入“ npm start”时,我会不断得到:
看起来语法错误在不存在的代码行中。
我对文件进行了三重检查,尝试引入一些语法错误,并检查是否捕获了这些错误。我确定这是文件npm尝试使用的。怎么来的?也许这是带有崇高文字的东西?你们有没有遇到过这样奇怪的问题?

最佳答案
您打开:
// route middleware to validate :id
router.param('id', function(req, res, next, id) {
并不要关闭它。
