python3 --version shows “NameError: name 'python3' is not defined” (2 answers)

Closed 2 years ago.

I am trying to install BeautifulSoup using pip in Python 2.7. I keep getting an error message, and can't understand why.

I followed the instructions to install pip, which was installed to the following directory: c:\Python27\Scripts\pip.exe, then I tried adding it to the path, and running the pip install package command.

tried it two different ways:

import sys
sys.path.append('C:\\Python27\\Scripts\\pip.exe')
pip install beautifulsoup4

import sys
sys.path.append('C:\\Python27\\Scripts')
pip install beautifulsoup4

both give me this error message:

>>> pip install beautifulsoup4
SyntaxError: invalid syntax

the shell is highlighting the word "install" and saying that it's invalid syntax.

I have no idea what's going on, so any help would be greatly appreciated.

Answer 1

pip is a command line tool, not Python syntax.

In other words, run the command in your console, not in the Python interpreter:

pip install beautifulsoup4

You may have to use the full path:

C:\Python27\Scripts\pip install beautifulsoup4

or even

C:\Python27\Scripts\pip.exe install beautifulsoup4

Windows will then execute the pip program and that will use Python to install the package.

Another option is to use the Python -m command-line switch to run the pip module, which then operates exactly like the pip command:

python -m pip install beautifulsoup4

or

python.exe -m pip install beautifulsoup4

The easy method that will work even in corrupted setup environment is :

To download ez_setup.py and run it using command line

python ez_setup.py

Answer 3

If you have more than one version of python installed, run the respective pip command.

For example for python3.6 run the following

pip3.6 install beautifulsoup4

To check the available command/version of pip and python on Mac run

ls /usr/local/bin

Answer 4

import os

os.system("pip install beautifulsoup4")

or

import subprocess

exe = subprocess.Popen("pip install beautifulsoup4")

exe_out = exe.communicate()

print(exe_out)
