Introduction
Matplotlib is one of the most popular data visualization tools for Python. It allows users to create all types of charts and graphs with little effort. However, sometimes its installation can cause headaches due to various errors. In this troubleshooting guide, we will examine the most common errors when installing Matplotlib and show you how to fix them.
System Requirements
Before installing Matplotlib, first, you need to ensure that your system’s configuration meets its requirements. Matplotlib requires Python 3.5 or higher and it supports different operating systems such as Windows, MacOS, or Linux. You also need to check if other dependencies like NumPy or Pandas are installed in your system.
Error Message 1: “module not found”
The error message “module not found” indicates that the required module is not installed in the system. In this case, we have to install the module using PIP from the command prompt. Just type pip install matplotlib in the command prompt and it will install the latest version.
Error Message 2: “unresolved setuptools deps”
This error occurs when setuptools, a package dependency that is required for Matplotlib, is not installed or out of date. We can solve this error by upgrading the setuptools package via the command prompt using “pip install –upgrade setuptools”.
Error Message 3: “certificate verify failed”
If you see an error message like “certificate verify failed”, it means that there is a problem with the SSL certificate. This usually happens on Mac OS because the SSL certificate is not up to date. To fix this problem, simply run the command “/Applications/Python {Python Version}/Install Certificates.command” in Terminal.
Error Message 4: can’t open file setup.py
If you receive an error message indicating that “can’t open file setup.py”, it implies that the path is incorrect. This error is typically caused by misplacing or deleting the required file. To solve this, make sure that you have downloaded the correct version of Matplotlib and extracted it to the appropriate directory.
Error Message 5: system cannot find the path specified
The message system cannot find the path specified usually appears when the shell environment has difficulty finding files or directories. This means that the command shell cannot locate the Python executable file. The solution to this problem is to modify your system’s environmental variable settings.
Error Message 6: “You must install a development environment…”
If you see the error message “You must install a development environment…”, it means that a C++ compiler is needed to build Matplotlib from source. To fix this, install the C++ build tool from Visual Studio or build tools at https://visualstudio.microsoft.com/downloads/.
Error Message 7: “unrecognized arguments”
This error occurs when you type unrecognized arguments in the command prompt. If this error occurs, double-check the command prompt that you have typed and try again.
Comparison Table
| Error Message | Cause | Solution |
|---|---|---|
| module not found | A module is missing | pip install matplotlib |
| unresolved setuptools deps | Old or missing setuptools package | pip install –upgrade setuptools |
| certificate verify failed | Missing or outdated SSL certificate | /Applications/Python{Python Version}/Install Certificates.command |
| can’t open file setup.py | Incorrect file path or missing file | Check file path and directory |
| system cannot find the path specified | Shell environment cannot locate Python executable | Modify system environmental variables |
| You must install a development environment… | A C++ compiler is missing | Install C++ build tools from Visual Studio |
| unrecognized arguments | Command prompt has unrecognized arguments | Double-check command prompt and try again |
