我不知道出了什么问题,因为我用Java编程了大约一年,从来没有遇到过这个错误.在Eclipse中进行编译和运行只需一分钟,现在我收到此错误:

    private void ReadUnitPrice()

        unitPrice = double.Parse(Console.ReadLine());
    }

这应该有效,但我遗漏了一些明显的东西.每当我输入一个double时,它就会给出错误:System.FormatException:输入字符串的格式不正确.请注意,'unitPrice'被声明为double.

如何在Google Cloud上查看日志消息？:https://console.cloud.google.com/logs

这是我在运行dev_appserver.py(本地运行)时在终端中看到的:

将显示应用程序日志消息和请求日志记录.
但是,当我查看部署的相同代码的日志时,我只能看到记录的请求:

我用来生成应用程序日志消息的代码如下:

问题:
这是我的docker-compose.yaml:

version: '2'

services:
    elasticsearch:
        image: 'elasticsearch:latest'
        ports:
            - "9200:9200"

            - "5001:5001"
            - "5201:5201"
            - "5202:5202"

             - elasticsearch
        volumes:
             - ./kibana.yml:/opt/kibana/config/kibana.yml

这是我的Dockerfile:

FROM logstash:latest

LABEL maintainer1.name="anon" \
      maintainer1.email="anon@mail.com" \
      maintainer2.name="myname" \
      maintainer2.email="myname@somemail.com"

RUN /opt/logstash/bin/logstash-plugin install logstash-input-log4j2-logstash2 logstash-output-syslog
# FIX: use `logstash-input-log4j2` instead of `logstash-input-log4j2-logstash2`?
# other plugins: logstash-input-http, logstash-input-log4j
COPY logstash.conf /etc/logstash/conf.d/logstash.conf

ENTRYPOINT ["logstash","-f","/etc/logstash/conf.d/logstash.conf", "--debug"]

这用于几天前建立就好,但是目前我收到以下错误消息: …

错误说明

我无法在Vagrant或Docker中挂载文件,因此看起来这是由某种权限错误引起的问题.
我的操作系统是Ubuntu 18.04 LTS (Bionic Beaver),SELinux据我所知,我没有运行任何访问控制模块.

有关错误的Vagrant相关讨论可以在另一个问题中找到: 无法在Vagrant中挂载文件

Docker故障排除

我无法使用docker-compose将文件挂载到Docker容器中,我正在尝试构建:https://github.com/fredrikaverpil/saltstack-docker

我将docker-compose文件中的卷设置为:

volumes:
  - ${PWD}/assets/master/etc/supervisor:/etc/supervisor
  - ${PWD}/assets/master/etc/salt:/etc/salt
  - ${PWD}/assets/master/var/cache/salt:/var/cache/salt
  - ${PWD}/assets/master/var/log/salt:/var/log/salt
  - ${PWD}/assets/master/srv:/srv

但是我在运行时得到了这个输出docker-compose up:

Creating network "saltstack_default" with the default driver

            "array = %d\n"
            "arr_size = %d\n", sizeof(array), sizeof(arr_size));
}

GCC编译器输出:

sizeof_test2.c: In function `sizeof_test2':

不知道为什么我收到这个错误,通过显示size_t类型的正确方法是printf什么？
