当我运行LinuxMintCinnamon18.30的更新管理器时,我会得到以下错误,并且不知道如何修复。
E: gcc-6-base: 1.0989:package is in a very bad inconsistent state; you should reinstall it before attempting configuration
E: libgcc1: 1.0989:dependency problems - leaving unconfigured
E: libc6: 1.0989:dependency problems - leaving unconfigured
在以下查询中需要更改哪些内容?我希望所有员工的date_of_leaving为空,或者date_of_leaving在过去60天内,或者date_of_leaving大于或等于Date.today或当前日期。
employees = @company.employees.where('date_of_leaving BETWEEN ? AND ? OR date_of_leaving IS NULL OR date_of_leaving IS >= Date.today', Date.today - 60, Date.today)
我尝试了另一种方式,也像下面这样。

我在这个项目上遇到了麻烦。我输入AM时间和PM时间。然而,当我到12 O‘’Clock时,一切都变得一团糟。它不断增加13,14,15等,有什么方法可以设置13=1,14=2,15=3等吗?
String format = "HH:mm:ss a";
SimpleDateFormat time = new SimpleDateFormat(format, Locale.US);
System.out.println("enter what time first person is leaving");
int leaving1 = in.nextInt();

我想安装gcc-4.4.3,为此我必须安装gmp 4.3.2.当我跑步时:

在下面的代码中,我试图找出线程如何处理同步块上的执行:
public class ThreadExp {
public static void main(String[] args) throws InterruptedException {
MyRunnable r = new MyRunnable();
Thread t1 = new Thread(r, "Thread1");
Thread t2 = new Thread(r, "Thread2");
t1.start();
我收到了一个关于定义字段的警告:
Ignored the logicalType property ("timestamp-millis"). It should probably be nested inside the "type" for the field.
{"name": "leaving", "type": ["null" ,"long"], "logicalType": "timestamp-millis", "default
简而言之,这是C#中提供的一个示例程序的略微修改的版本:
using System;
using System.Threading;
namespace SemaphorTest
{
class Program
{
static Semaphore gate = new Semaphore(3, 3);
static void Main(string[] args)
{
for (int i = 0; i < 5; i++)
{

我正在尝试在我的ubuntu服务器上安装rtorrent。
我运行了这些命令,它们运行得很好。

然后,当我尝试使用make install时,我想它没有安装,因为在主目录中没有创建.rtorrent.rc',运行rtorrent返回了这个错误,下面的rtorrent: error while loading shared libraries: libtorrent.so.11: cannot open shared object file: No such file or directory是

我想要一种退出开始/结束块的方法,同时仍然分配它的结果分配给的变量。
def foo
@foo ||= begin
puts "running"
return "leaving early" if true # would be some sort of calculation
# Other calculations
end
end
我希望发生的事
> foo
running
=> leaving early
> foo
=> leaving early
实际发生了什么
> foo
