我做了这个简单的程序:

package main.java;

public class start {
    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

并得到了这个错误.我不知道发生了什么,

- 由Elliot B解决.谢谢!也可以考虑其他修改.

这是结果.谢谢大家,快速回答!http://dl.dropbox.com/u/18785762/Rust/index.html

我正在用javascript编写一个游戏,并且我希望将用于匹配块ID的文件保存到地图编译器中单独的.js文件中的文件,以便我可以轻松编辑.但是,ID存储在一个数组中,我似乎无法正确使用return函数.有帮助吗？

drawmap.js:

function drawmap() {

    var images = BlockID();

    var level = [
    "ssssssssssssssssssssss",
    "sgggggggggCCCCCdddddss",
    "ssssssssss     sssssss"
    ];

    var top = 100;
    var left = 100;
    var mytop = top;
    var myleft = left;
    for (y=0; y<level.length; ++y) {
        var row = level[y];
        for (x=0; x < row.length; ++x) {
            var c = row.charAt(x);
            if(c != ' ') {
                img_create(images[c], mytop, myleft);
            }
            mytop += 13;
            myleft += 27;
        }
        mytop = top + (y+1)*13; …

每当我运行我的代码时,我都会收到错误{"error": "Please use POST request"}有人知道这个错误意味着什么吗？我在jsfiddle中 的代码:http://jsfiddle.net/Aidoboy/AdzwC/12/代码:

/*jslint browser: true, devel: true */

function Submit() {
    //"use strict";
    alert("running");
    document.forms.form.submit();
    var owed = 0;

    function calc(n, o) {
        if (n >= 90) {
            owed = owed + 1;
            if (n >= 95) {
                owed = owed + 1;
            }
        }
        else if (o >= 80) {
            owed = owed + 0.5;
        }
        if (n > o) {
            owed = owed + 0.5 * (n - …

我不知道为什么会这样。这是函数：

def scanWallDir(basedir, scansubdirs=True):
    wallsOut = []
    for entry in os.scandir(basedir):
        if entry.is_file():
            print(("file " + entry.name))
        elif entry.is_dir():
            print(("dir  " + entry.name))

和错误：

/usr/bin/python2.7 /home/aidan/Code/ulwscs/ulwscs.py
Traceback (most recent call last):
  File "/home/aidan/Code/ulwscs/ulwscs.py", line 38, in <module>

    for entry in os.scandir(basedir):
AttributeError: 'module' object has no attribute 'scandir'

Process finished with exit code 1

有谁知道会发生什么？

我正在尝试使用 Beast 制作一个 CMake 项目，并且它已从 中的源代码正确安装/usr/local/include/boost，但我无法让 CMake 找到它。不过，我觉得这可能是一个3.10.2，所以我累3.11.4和3.12.0-rc1，但既不工作。有谁知道该怎么做？

环境：Windows CLion 2018.1.5 和 WSL 上的 Ubuntu 18.04LTS。

尝试运行 CMake 时，出现以下错误：

我从JSLint收到以下错误,我无法理解它们:

有关这些的任何帮助吗？

这是我的PowerShell脚本:

$dir = ([io.fileinfo]$MyInvocation.MyCommand.Definition).DirectoryName

Get-ChildItem -Path .\ -Filter *.png -Recurse -File | Where-Object {$_.Name -match ".+[\]]+.png"} | ForEach-Object {
    echo $_.FullName $(Test-Path $_.FullName)
    Remove-Item $_
    echo $_.FullName $(Test-Path $_.FullName)
}

回声提供实际的文件名,但Test-Path解析为False,并且没有删除任何内容.
