在这种情况下，我尝试创建一个计数器，每次有人访问我的网站时，都会从views.json文件中读取变量，然后在数字中添加一个，然后用新数字更新.json。 。但是，当我在repl.it项目中对其进行测试时，出现错误消息
ReferenceError: writeFileSync is not defined

如果您知道，请告诉我，我不知道这意味着什么。

您可以这样做，只是修复了一些错误。
哦，您应该使用writeFileSync，以避免不会同时编辑该文件。
问题是，为什么不使用数据库？修复并发写入要快得多。

我发现我没有用fs做错了。
writeFileSync("views.json", data, finished);
当我只需要做
fs.writeFileSync("views.json", data[,finished]);
