如何在linux服务器上安装带有的幻影和selenium？

Question

我正在使用硒和幻影作为我的网络刮刀。所有的工作与我的测试窗口应用程序。尝试将此代码更新添加到我的主应用程序中，该应用程序与docker-组合一起部署，我得到以下内容：selenium.common.exceptions.WebDriverException: Message: 'phantomjs' executable needs to be in PATH.。

我该怎么解决这个问题？目前，我的docker-compose.yml有以下代码：

version: '3.1'

services:

  tgbot:
    container_name: bot
    build:
      context: .
    command: python app.py
    restart: always
    environment:
      WEBAPP_PORT: 3001
    env_file:
      - ".env"
    # bot start after load db
    ports:
      - 8443:3001
    networks:
      - botnet

  phantomjs:
    image: shufo/phantomjs
    command: --webdriver 8901

networks:
      botnet:
        driver: bridge

还有我的python代码：

from selenium import webdriver
driver = webdriver.PhantomJS()

码头文件：

FROM python:latest

RUN mkdir /src
WORKDIR /src
COPY requirements.txt /src
RUN pip install -r requirements.txt
COPY . /src

我使用幻影，因为我正在抓取的网页有JS。铬不起作用

您的配置有几个问题：

1. 您的机器人代码在不同的容器中工作。不是那个发射幻影的。这就是为什么它找不到executable.
2. You运行的幻影is容器，它不在您的代码
3. 的同一网络中，有一些无用的信任似乎是从其他示例复制的。
4. 强制您的容器重新启动。即使在成功退出代码之后，它也将重新启动。

，下面是如何运行所有内容的完整示例：

1. 创建空文件夹myfolder，并将包含以下内容的app.py放在那里：

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(command_executor='http://phantomjs:8901/wd/hub/',desired_capabilities=DesiredCapabilities.PHANTOMJS)

myfolder

• Put

• 将requirements.txt文件放在Dockerfile到myfolder

之后

FROM python:latest

WORKDIR /configs
COPY requirements.txt requirements.txt
RUN pip install -r requirements.txt

myfolder

1. 将以下docker-compose.yml放置到

version: '3.1'

services:

  tgbot:
    build: .
    container_name: bot
    volumes:
      - .:/apps
    command: python /apps/app.py
    depends_on:
      - phantomjs
    networks:
      - botnet

  phantomjs:
    container_name: phantomjs
    image: shufo/phantomjs
    command: --webdriver 8901
    networks:
      - botnet

networks:
  botnet:
    driver: bridge

1. cd myfloder，docker-compose up

输出：
