Are you experiencing an error message that says “No module named ‘requests'” or “Import ‘requests’ could not be resolved from source Pylance”? Don’t worry; you’re not alone.
These errors are common when working with Python projects that require the use of the popular requests module. In this article, we will explore the reasons for these errors and how to troubleshoot them.
Troubleshooting “No module named ‘requests'”
One of the most common reasons for the “No module named ‘requests'” error is that the requests module is not installed on your system. Let’s go through some troubleshooting steps to resolve this issue.
Installing the requests module
If you’re using an IDE, like PyCharm or Visual Studio Code, you can install the requests module from the command palette or the terminal. Open the command palette by pressing Ctrl + Shift + P (Windows/Linux) or Command + Shift + P (macOS) and search for “Python: Install Package.” Type in “requests” and press Enter to install the package.
It’s also a good practice to use a virtual environment while installing packages to avoid conflicts with other projects. You can create a virtual environment by running the following command in your terminal:
python -m venv env
Once you’ve created a virtual environment, activate it, and install the requests module using pip:
source env/bin/activate # For Linux/Unix
.envScriptsactivate # For Windows
pip install requests
You can replace “requests” with any other package you want to install.
Checking if the package is installed
If the package was installed successfully, you should see it listed when you run the following command in your terminal:
pip show requests
If you get an error message saying “No distributions found for requests,” the package isn’t installed. Try reinstalling the package or check if you’re using the correct Python interpreter.
Verifying correct Python interpreter
Sometimes, the issue might be that you’re using the wrong Python interpreter. Double-check that you’re using the correct interpreter for the project you’re working on.
You can do this by going to your IDE’s settings and selecting the correct interpreter. If you’re using Visual Studio Code, you can select the interpreter by using the Python extension’s “Python: Select Interpreter” command.
Press Ctrl + Shift + P (Windows/Linux) or Command + Shift + P (macOS), search for “Python: Select Interpreter,” and choose the appropriate interpreter from the list.
Reinstalling the package
If none of the above troubleshooting steps work, you can try uninstalling and reinstalling the requests package. To uninstall the package, run the following command in your terminal:
pip uninstall requests
Then reinstall the package using pip:
pip install requests
That’s it for “No module named ‘requests'” error. Let’s move on to the “Import ‘requests’ could not be resolved from source Pylance” error.
Troubleshooting “Import ‘requests’ could not be resolved from source Pylance”
Pylance is a fast, feature-rich language server for Python that provides rich type analysis. If you’re using Pylance as your language server, you might encounter the “Import ‘requests’ could not be resolved from source Pylance” error.
Here are some troubleshooting steps to resolve this error.
Selecting the correct Python interpreter
First, make sure that you’ve selected the correct Python interpreter for your project. In Visual Studio Code, you can change the Python interpreter by using the “Python: Select Interpreter” command.
Press Ctrl + Shift + P (Windows/Linux) or Command + Shift + P (macOS), search for “Python: Select Interpreter,” and choose the appropriate interpreter from the list.
Installing requests using the terminal
One solution to resolve this error is to install the requests module using the terminal. Open the Visual Studio Code terminal and activate your virtual environment (if you’ve created one), then install the requests module using pip:
source env/bin/activate # For Linux/Unix
.envScriptsactivate # For Windows
pip install requests
Disabling Pylance warning
If the above steps don’t work, you can consider disabling the Pylance warning for this specific error. Add the following comment at the top of your file:
# type: ignore
This tells Pylance to ignore the “Import ‘requests’ could not be resolved from source Pylance” error and allow the import statement to go through.
Conclusion
These are the troubleshooting steps you can take to resolve “No module named ‘requests'” and “Import ‘requests’ could not be resolved from source Pylance” errors. Remember to use a virtual environment to avoid conflicts with other projects, and double-check that you’re using the correct Python interpreter.
You can also disable Pylance warnings temporarily to allow your code to run. Hopefully, this article has been informative and helpful in resolving these common Python errors.
3) Installing requests on different platforms
The requests module is available on various platforms such as Windows, macOS, and Linux. Here are some simple steps to install requests on different platforms:
Installing requests on Windows
Windows users can install the requests module by using the Command Prompt (CMD) or PowerShell. Firstly, open the Command Prompt as an administrator, navigate to the project’s working directory and create a virtual environment:
python -m venv env
.envScriptsactivate
Then, use pip to install the requests module:
pip install requests
Installing requests on macOS or Linux
For macOS and Linux users, you can install the requests module using the terminal. Firstly, open the terminal and create a virtual environment:
python -m venv env
source env/bin/activate
Then, install the requests module using pip:
pip install requests
Note that when installing requests on Linux, you might need to use the ‘sudo’ command with pip to get administrative privileges:
sudo pip install requests
You can also create a py alias in your system’s .bashrc file to avoid typing ‘python3’ command each time:
alias py=python3
Installing requests in Visual Studio Code
If you’re using Visual Studio Code, you can install the requests module by using the built-in terminal. Firstly, create a virtual environment and activate it:
python -m venv env
source env/bin/activate # For Linux/Unix
.envScriptsactivate # For Windows
Then, install the requests module:
pip install requests
Make sure you’ve selected the correct Python interpreter for the project by using the “Python: Select Interpreter” command.
Installing requests in PyCharm
PyCharm also provides a terminal where you can install the requests module. Firstly, open the terminal by pressing Alt+F12.
Then, create a virtual environment and activate it:
python -m venv env
source env/bin/activate # For Linux/Unix
.envScriptsactivate # For Windows
Finally, use pip to install the requests module:
pip install requests
Make sure you have selected the correct Python interpreter in the “Python Interpreter” settings.
Installing requests in Anaconda
If you’re using Anaconda, you can install the requests module using the Anaconda Navigator or Anaconda Prompt. Firstly, open the Anaconda Navigator and create a new environment.
Then, activate the environment and install the requests module using conda:
conda install requests
Alternatively, you can use the Anaconda Prompt to install the requests module:
conda create -n mypythonenv # Create new environment
conda activate mypythonenv # Activate the new environment
conda install requests # Install requests
Installing requests in Jupyter Notebook
Jupyter Notebook also allows you to install the requests module using the “!” operator in a code cell. Firstly, create a new notebook and a virtual environment:
python -m venv env
source env/bin/activate # For Linux/Unix
.envScriptsactivate # For Windows
Install the ipykernel to enable the virtual environment in Jupyter:
pip install ipykernel
python -m ipykernel install --user --name=myenv # myenv is the name of virtual environment
Finally, install requests module using the following command:
!pip install requests
Note that you need to restart the kernel to use the new virtual environment. 4) Promotion of author’s book
