Question

我寫了一個 python 腳本並使用 selenium 驅動程序。 我收到以下錯誤：

    from selenium import webdriver
ModuleNotFoundError: No module named 'selenium'

當我運行命令時： pip install selenium ， output 是：

Requirement already satisfied: selenium in d:\windows\system32\config\systemprofile\appdata\local\programs\python\python36\lib\site-packages
Requirement already satisfied: urllib3 in d:\windows\system32\config\systemprofile\appdata\local\programs\python\python36\lib\site-packages (from selenium)
You are using pip version 9.0.1, however version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

你能幫忙解決這個問題嗎？

Answer 1

此錯誤消息...

Requirement already satisfied: selenium in d:\windows\system32\config\systemprofile\appdata\local\programs\python\python36\lib\site-packages 
Requirement already satisfied: urllib3 in d:\windows\system32\config\systemprofile\appdata\local\programs\python\python36\lib\site-packages (from selenium) 
You are using pip version 9.0.1, however version 19.3.1 is available. 
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

...暗示您使用的是非常古老的pip v9.0.1 。 您需要使用命令提示符下的以下命令將pip v19.3.1更新到pip v19.3.1的最新可用版本：

python -m pip install --upgrade pip
