Python : no module named selenium

Solution 1:

As you mentioned you are using Python 3.6 following the steps :

• Open Command Line Interface (CLI) and issue the command python to check if Python is properly installed :

  C:\Users\username>python
  Python 3.6.1 (v3.6.1:69c0db5, Jan 16 2018, 17:54:52) [MSC v.1900 32 bit (Intel)]
   on win32
  Type "help", "copyright", "credits" or "license" for more information.
  >>>
  

• Ensure pip is working properly :

  C:\Users\username>pip
  
  Usage:
    pip <command> [options]
  
  Commands:
    install                     Install packages.
    download                    Download packages.
    uninstall                   Uninstall packages.
    freeze                      Output installed packages in requirements format.
    list                        List installed packages.
    show                        Show information about installed packages.
    check                       Verify installed packages have compatible dependencies.
    search                      Search PyPI for packages.
    wheel                       Build wheels from your requirements.
    hash                        Compute hashes of package archives.
    completion                  A helper command used for command completion.
    help                        Show help for commands.
  
  General Options:
    -h, --help                  Show help.
    --isolated                  Run pip in an isolated mode, ignoring environment variables and user configuration.
    -v, --verbose               Give more output. Option is additive, and can be used up to 3 times.
    -V, --version               Show version and exit.
    -q, --quiet                 Give less output. Option is additive, and can be used up to 3 times (corresponding to WARNING, ERROR, and CRITICAL logging levels).
    --log <path>                Path to a verbose appending log.
    --proxy <proxy>             Specify a proxy in the form [user:passwd@]proxy.server:port.
    --retries <retries>         Maximum number of retries each connection should attempt (default 5 times).
    --timeout <sec>             Set the socket timeout (default 15 seconds).
    --exists-action <action>    Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort.
    --trusted-host <hostname>   Mark this host as trusted, even though it does not have valid or any HTTPS.
    --cert <path>               Path to alternate CA bundle.
    --client-cert <path>        Path to SSL client certificate, a single file containing the private key and the certificate in PEM format.
    --cache-dir <dir>           Store the cache data in <dir>.
    --no-cache-dir              Disable the cache.
    --disable-pip-version-check
                                Don't periodically check PyPI to determine
                                whether a new version of pip is available for
                        download. Implied with --no-index.
  

• Install latest selenium through pip :

  C:\Users\username>pip install -U selenium
  Collecting selenium
    Downloading selenium-3.8.1-py2.py3-none-any.whl (931kB)
      100% |¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦| 942kB 322kB/s
  Installing collected packages: selenium
  Successfully installed selenium-3.8.1
  

• Confirm that Selenium is installed :

  C:\Users\username>pip freeze
  selenium==3.8.1 
  

• Open an IDE (e.g Eclipse, PyCharm) and write a simple program as follows :

  from selenium import webdriver
  
  driver = webdriver.Firefox(executable_path="C:\\path\\to\\geckodriver.exe")
  driver.get('https://stackoverflow.com')
  

• Execute the program on which Firefox Quantum Browser will be initiated and the url https://stackoverflow.com will be accessed.

Python Download Location (Windows) :

Python (for Windows) can be download from the following location :

https://www.python.org/downloads/

Solution 2:

I'm on VS Code in Windows 10, and here's how I solved it.

You need to pay attention to where the Python is located (in my case),

1) C:\Users\_Me_\AppData\Local\Programs\Python\Python38\ 

and where the Python looks for libraries/packages, including the ones installed using pip (again, in my case),

2) C:\Users\_Me_\AppData\Roaming\Python\Python38\

I don't know why these two locations are different (gotta fix it at some point). It seemed that Python was running from the first location, but it was looking for libraries in the second!:/

Anyway, since I have limited experience in Python , I just copied the \Lib\site-packages from the first location (including selenium folders) to \site-packages in second one in hopes of solving the issue, which worked out for me!

How to check for there locations

1) Open Python CLI, typed the following command:

which python

2) Open Python CLI, typed the following commands (From this answer):

>>> import site
>>> site.USER_SITE

EDIT

Since this seems a temporary solution, I uninstalled Python and reinstalled it again in a proper directory (other than the default install directory), and now which python and which pip point to the same folder! Problem solved!
