webdriver 问题小记

在尝试 Jenkins 创建构建任务 这个项目时遇到一些问题，本文用于记录解决方法（可以说是很小白的方法了）。

问题主要在这一步：C:\Users\wis01>python d:/py_tests.py

输出为：

这里有两种错误：

1、注册表导致

1. [5956:4996:0710/155156.898:ERROR:install_util.cc(589)] Unable to create registry key HKLM\SOFTWARE\Policies\Google\Chrome for reading result=2
   

复制代码

找不到注册信息。

解决方法：

1）打开注册表编辑器

1. a) 快捷键win+R
   
2. b) 输入：regedit
   
3. c) 打开regedit.exe

复制代码

2）找到并按顺序展开以下项目：

1. -HKEY_LOCAL_MACHINE
   
2.     -SOFTWARE
   
3.         -Policies

复制代码

3）在Policies下创建Chrome项：

1. a) 选中Policies
   
2. b) 点击右键
   
3. c) 新建 - 项(k)
   
4. d) 将该项命名为：Google

复制代码

4）在Google下创建Chrome项：

1. a) 选中Google
   
2. b) 点击右键
   
3. c) 新建 - 项(k)
   
4. d) 将该项命名为：Chrome

复制代码

5）在Chrome下新建MachineLevelUserCloudPolicyEnrollmentToken字串：

1. a) 选中Chrome
   
2. b) 点击右键
   
3. c) 新建 - 字符串值(s)
   
4. d) 将该字符串命名为：MachineLevelUserCloudPolicyEnrollmentToken

复制代码

6）若原本已有Google、Chrome项，则直接在下面添加第五步中的字符串值即可。

2、webdriver导致

1. WebDriverException: Message: unknown error: cannot determine loading status
   
2.     from unknown error: missing or invalid 'entry.level'
   
3.       (Session info: chrome=67.0.3396.99)
   
4.       (Driver info: chromedriver=2.29.461591 (62ebf098771772160f391d75e589dc567915b233),platform=Windows NT 6.1.7601 SP1 x8
   
5.     _64)
   

复制代码

webdriver与Chrome两者版本不匹配（一般来说，两者均保持最新即可）。

解决方法：

1）更新Chrome

2）更新webdriver
