我正在从源代码nenuadrian / browserquest中设置一个browserquest服务器。当我尝试运行node server / js / main.js来启动服务器时，我收到以下错误消息：
internal/fs/utils.js:409 throw err; ^
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be one of type string, Buffer, or URL. Received type undefined at Object.fs.lstatSync (fs.js:932:3) at Class.init (/var/www/html/games/browserquest/server/js/map.js:14:13) at new Class (/var/www/html/games/browserquest/server/js/lib/class.js:50:23) at Module._compile (internal/modules/cjs/loader.js:696:33) at Object.Module._extensions..js (internal/modules/cjs/loader.js:713:10) at Module.load (internal/modules/cjs/loader.js:612:32) at tryModuleLoad (internal/modules/cjs/loader.js:551:12) at Function.Module._load (internal/modules/cjs/loader.js:543:3) at Module.require (internal/modules/cjs/loader.js:650:17) at require (internal/modules/cjs/helpers.js:20:18)
这是导致上述错误的server / js / utils.js中的代码。我没有编辑此代码，它似乎适用于托管此游戏的其他人。：
var Utils = {},
sanitizer = require('sanitizer'),
Types = require("../../shared/js/gametypes");
module.exports = Utils;
Utils.sanitize = function(string) {
// Strip unsafe tags, then escape as html entities.
return sanitizer.escape(sanitizer.sanitize(string));
};
Utils.random = function(range) {
return Math.floor(Math.random() * range);
};
Utils.randomRange = function(min, max) {
return min + (Math.random() * (max - min));
};
Utils.randomInt = function(min, max) {
return min + Math.floor(Math.random() * (max - min + 1));
};
Utils.clamp = function(min, max, value) {
if(value < min) {
return min;
} else if(value > max) {
return max;
} else {
return value;
}
};
Utils.randomOrientation = function() {
var o, r = Utils.random(4);
if(r === 0)
o = Types.Orientations.LEFT;
if(r === 1)
o = Types.Orientations.RIGHT;
if(r === 2)
o = Types.Orientations.UP;
if(r === 3)
o = Types.Orientations.DOWN;
return o;
};
Utils.Mixin = function(target, source) {
if (source) {
for (var key, keys = Object.keys(source), l = keys.length; l--; ) {
key = keys[l];
if (source.hasOwnProperty(key)) {
target[key] = source[key];
}
}
}
return target;
};
Utils.distanceTo = function(x, y, x2, y2) {
var distX = Math.abs(x - x2);
var distY = Math.abs(y - y2);
return (distX > distY) ? distX : distY;
};
答案 0 :(得分：0)
我面临着同样的问题。似乎使用较新版本的节点会导致这些错误。我尝试使用8.9.3并成功。
此外，package.json的模块版本设置为最新，这会导致其他冲突。以下依赖项列表对我有用。
