早上在linux下用selenium启动Chrome时出现问题:
报错:

Traceback (most recent call last):
File "get2.py", line 62, in <module>
browser = webdriver.Chrome()
File "/root/.pyenv/versions/anaconda3-5.1.0/lib/python3.6/site-packages/selenium/webdriver/chrome/webdriver.py", line 75, in __init__

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
(unknown error: DevToolsActivePort file doesn‘t exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
(Driver info: chromedriver=2.43.600233 (523efee95e3d68b8719b3a1c83051aa63aa6b10d),platform=Linux 4.9.0-6-amd64 x86_64)

解决方案:
加上代码:

from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument(‘--no-sandbox‘)
chrome_options.add_argument(‘--disable-dev-shm-usage‘)
chrome_options.add_argument(‘--headless‘)
browser = webdriver.Chrome(chrome_options=chrome_options)

其中
“–no-sandbox”参数是让Chrome在root权限下跑
“–headless”参数是不用打开图形界面
可以额外加这些参数获得更好体验

chrome_options.add_argument(‘blink-settings=imagesEnabled=false‘)
chrome_options.add_argument(‘--disable-gpu‘)

系统版本:

        Red Hat 4.8.2-16

一、首先安装phantomjs

        1)、下载程序文件

wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-x86_64.tar.bz2

             (注意:32位ubuntu下载链接是https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-i686.tar.bz2)

         2)、解压文件

tar -xvf phantomjs-1.9.7-linux-x86_64.tar.bz2

         注意:有些可能还需要修改合适的地址和名字  改不改都行 不是必要因素。
二、配置环境变量

          方法一:(全局环境变量)

                  vi  /etc/profile
                        加入以下内容:
                            export PATH=$PATH:/root/phantomjs/bin    (红色字体为安装目录)
                            PATH=$PATH:$HOME/bin
                            export PATH
                 这里要执行 source /etc/profile, 以另刚才的改动生效。

          方法二:(用户环境变量)

                  vi  .bash_profile

                        在export PATH上添加以下内容:        
                              export PATH=/root/phantomjs/bin/phantomjs:$PATH  (红色字体为安装目录)

三、命令行输入

                  phantomjs --version 如果能看到版本说明OK了  (注意 是  - - version 中间没有空格)

 

如果报错如下::

selenium.common.exceptions.WebDriverException: Message: Service /Users/Me/.npm-packages/bin/phantomjs unexpectedly exited. Status code was: 127


安装依赖包fontconfig 命令如下:
yum --skip-broken install fontconfig freetype libfreetype.so.6 libfontconfig.so.1
