How to Install Esptool on Windows 10

  • by

This article on how to install Esptool on Windows 10 was written because I remembered that I had been for a time wondering how to do it. If you’re a Windows user, you’re probably used to graphical interfaces. You’re also used to easy installs – download an installer file, run or open the file, follow the installation instructions, and it’s done.

Installing Esptool is a two-part process. First you download and install Python. Then, you run a Python command to install Esptool.

pip install esptool

Esptool runs on the scripting and programming language Python. Therefore, we need to install Python first before we install Esptool.

How to Install Python

On Windows 10, you may simply type “python” on the Windows search box beside the Windows Start button and download Python from the Windows App Store. An issue with this procedure is that you may get an older version of Esptool from the App Store.

If you want to get the latest version of Python, downloading the installer from the Esptool download page is the way to go.

Run the downloaded Esptool installation file. As of this writing, the installation file for the latest version is python-3.8.1.

You may want to put a check mark on the Add Python 3.8 to PATH before clicking on the Install Now button. This will make it easier to start the Python and the Esptool program. Without the check mark, before you can run Python or Esptool, you would need to find the directory where you installed Python. You then would have to change your current directory to the Python’s folder.
