Do we need to install Selenium each time we open and execute a new project using Python?

Question

I have selenium installed and chrome driver in a python project, when i create a new project is says it can't recognize the selenium module.

Does this mean with each project I'll need to install selenium again?

Answer 1

No, you don't need to install Selenium for each project. The installation procedure is only once in a lifetime using either of the following commands through command line interface:

• Using pip:

  pip install selenium
  

• Using pip3:

  pip3 install selenium

Upgrading pip

However, you would need to keep on upgrading pip periodically:

• On linux or macos:

  pip install -U pip
  

• On windows:

  python -m pip install -U pip
  

• Or

  C:\Users\username>python -m pip install --upgrade pip

Upgrading Selenium

As a mandatory measure you need to upgrade the Selenium bindings to keep in sync with the release of each stable version as follows:

C:\Users\username>pip install -U selenium
Collecting selenium

You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Reference

You can find a detailed relevant discussion in:

• How to resolve Selenium with Python: TypeError: 'module' object is not callable
• TypeError: 'module' object is not callable error with driver=webdriver(“C:\Python34\Lib\site-packages\selenium\webdriver\chromedriver.exe”)
• TypeError: 'module' object is not callable error running pip install selenium

Answer 2

You need to initialize browser in selenium each time when you are trying to run your automation test.

driver = webdriver.Chrome('./chromedriver')
driver.get("https://www.python.org")
print(driver.title)

You dont need to install selenium everytime you just need to initialize browser session wwhen you are trying to run your test from differnt project.

Also use pip to install the selenium package.

Try below command to install selenium using pip command after installing python

pip install selenium

You will find your dependancies under Python\Lib\site-packages

Answer 3

You don't need every time , you need use by giving path and locate to folder in your machine

Answer 4

yes you need to. In cases where you create virtual environment for each projects. It is better to have it install into the project virtual environment. This will save you a lot of stress debugging your code later in future.
