【问题描述】：
以下是我安装 selenium 时的结果：
ubuntu@ip-172-31-23-71:~$ pip3 install selenium

You are using pip version 8.1.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
这是我的python脚本（helloworld.py）：
#!/usr/bin/python3
from selenium import webdriver
def testPrint():
return "Test print"
def application(environ,start_response):
status = '200 OK'
html = '<html>\n' \
'<body>\n' \
'<div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;">\n' \
'Hello world! \n' + testPrint() + \
'</div>\n' \
'</body>\n' \
'</html>\n'
response_header = [('Content-type','text/html')]
start_response(status,response_header)
return [html]
正常情况下编译：
ubuntu@ip-xxx-xx-xx-xx:/var/www/html/pythonscrape$ python3 helloworld.py
ubuntu@ip-xxx-xx-xx-xx:/var/www/html/pythonscrape$
如你所见，编译“from selenium import webdriver”这一行没有问题
ubuntu@ip-xx-xx-xx-xx:/var/www/html/pythonscrape$ python3
Python 3.5.2 (default, Oct 8 2019, 13:06:37)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from selenium import webdriver
>>>
所以你看不到错误。
但是，当我通过浏览器/Apache/wsgi 运行它时，它找不到我的 selenium 模块。这是日志输出：
[Fri Feb 21 14:43:34.952035 2020] [wsgi:error] [pid 15279] [client 108.210.66.3:64700] mod_wsgi (pid=15279): Exception occurred processing WSGI script '/var/www/html/pythonscrape/helloworld.py'.

这是我的 helloworld.conf 文件：
WSGIScriptAlias /helloworld /var/www/html/pythonscrape/helloworld.py
ErrorLog /var/www/html/pythonscrape/error_log.txt

如何让 selenium 模块被 Apache/wsgi 识别？
【问题讨论】：
-
selenium 安装在您的项目所在的同一驱动器上吗？我回答了一个类似的问题here
-
您好 Kosaro，我如何找出 selenium 的安装位置？当我输入“which selenium”时，它返回空白。
-
在python终端
import seleniumselenium.__file__应该给你模块的文件路径 -
嗨 Kosaro，它显示 - /home/ubuntu/.local/lib/python3.5/site-packages/selenium/__init__.py 我需要在我的配置中包含它吗？跨度>
