Errors While Running Scripts

Python or Python3

If you are running on Windows you might have to adjust some files. If you would like to install all the dependencies or run programs then you have to use:

python nameofthefile.py
#and for pip
pip install -r requirements.txt

For Linux, MacOS, or any other Unix-like operating system, the python3 command is commonly used to differentiate it from the python command which is associated with Python 2.

Where is Python installed?

If you are running Windows, try installing either a WSL (Windows Subsytem for Linux) terminal, Powershell terminal or Git Bash terminal. The reason is that you will be able to use Linux commands and follow along the steps.

If you are running MacOS or Linux (or Windows with any of the aforementioned terminals), type:

which python3

This should return the path of the python3 command. Example: /usr/bin/python3 - this is the path where the python3 executable is stored.

Using chmod and Bash Scripts

If you want to run the eapp file or you want to create a new bash script, you must include a shebang indicating the location of the Python interpreter.

Example:

#!/usr/bin/env python3 

Making an executable:

chmod +x nameofthefile

Note: The first line of nameofthefile must be the shebang or location of the interpreter.

Doing this will create an executable, meaning that you will be able to run the file by typing:

./nameofthefile
#or
bash nameofthefile

Error: Wrong Interpreter Python3^M - This Error Usually Happens on Unix-like systems (MacOS and Linux)

Solution: this file was generated in a Windows machine running a WSL (Debian). One way to fix this error is to use the dos2unix package.

Downloading on MacOS

brew install dos2unix

Downloading on Linux (Debian, Ubuntu, or Linux Mint)

Check your distribution package manager i.e in Fedora you would use dnf instead of apt

sudo apt-get install dos2unix

Using dos2unix

dos2unix nameofthefile.py
