Node.js: Python not found exception due to node-sass and node-gyp

😱 Node.js: Python not found exception due to node-sass and node-gyp

🚀 The Problem:

So, you were happily building your Jenkins environment, everything running smoothly, until suddenly you hit a brick wall. 😫 The build started failing, and you discovered it was due to an internal dependency issue with node-gyp and node-sass. Digging into the logs, you found the culprit: node-gyp v3.5.0 from node-sass v3.8.0 requires Python to be installed.

🤔 The Question:

Now, what can you do? Can you install a different version of node-sass to bypass this issue? Or is there a better solution? After all, your build was running just fine until this morning on the same environment.

🕵️‍♀️ The Investigation:

First things first, let's understand what's happening here. node-gyp is a tool that allows you to compile native addon modules for Node.js. It relies on Python as a prerequisite. If Python is not found, it throws an error and your build fails.

🛠️ The Solution:

Fear not! We have some easy solutions for you:

1. Install Python: The most straightforward solution is to install Python. Make sure you have Python installed on your system and that it's added to your PATH environment variable. You can download the latest stable version of Python from the official website (https://www.python.org/downloads/).

2. Set the PYTHON env variable: If Python is already installed but you're still encountering the same issue, try setting the PYTHON environment variable. Set it to the location of your Python executable. This can be done using the following command in your shell:

   set PYTHON=path/to/python

3. Upgrade node-sass: If for some reason you can't or don't want to install Python, you can try upgrading node-sass to a version that doesn't have this requirement. The good news is that newer versions of node-sass (4.x.x and above) no longer have a dependency on node-gyp and Python. You can upgrade node-sass by running the following command in your project directory:

   npm install node-sass@latest

4. Use a different build tool: If none of the above solutions work for you, you might consider using a different build tool that doesn't rely on node-gyp and Python. There are alternatives available, such as sass, which is a pure JavaScript implementation of Sass. You can install sass by running the following command in your project directory:

   npm install sass
