I’m experiencing issues while trying to install npm packages on Windows 10 with Node.js version 16.14.2 and npm 8.3.1. Each time I execute npm install, I receive this error:

It seems that there might be a problem with Python compatibility that arises when node-gyp attempts to compile native modules. I’ve also tried installing node-gyp separately, but the outcome remains unchanged. Has anyone faced a similar build error?
This error happens when node-gyp tries to run Python but can’t because of version conflicts. It’s super common on Windows where the default Python doesn’t match what node-gyp expects. First, make sure you’ve got the right tools installed. Run npm install --global windows-build-tools to get both Python and the Visual Studio components you need for compiling native modules. If you want to keep your current Python setup, just install Visual Studio Build Tools separately - node-gyp needs those C++ build tools to work.
Check if you’ve got multiple Python versions installed - that’s usually what triggers the syntax error. Node-gyp gets confused and picks the wrong one. Try removing your Python path from system variables temporarily and let node-gyp auto-detect it. Fixed it for me last time this happened.
Been dealing with this exact nightmare for years on different projects. The Python path issue is just the tip of the iceberg with node-gyp builds.
I stopped wrestling with Python versions and build tools - automated the whole dev environment setup using Latenode instead. Built a workflow that detects the OS, installs the right Python version, sets up build tools, and handles npm installs without any manual path configuration.
The workflow runs when someone joins the project or dependencies change. No more “works on my machine” problems or spending hours debugging node-gyp failures. Everyone gets identical setups and native modules compile perfectly.
You can set it to monitor package.json changes and auto-rebuild when needed. Way better than manually fixing Python paths every few months when something breaks.
Had this exact problem with a React project needing sass compilation. node-gyp tries to run Python but hits encoding or path issues. I switched to yarn instead of npm - it handles Python detection way better and skips most node-gyp headaches. If you’re staying with npm, install sass-embedded instead of regular sass. It has precompiled binaries so you avoid native compilation entirely. Also check your Windows username doesn’t have special characters or spaces - that breaks Python path parsing even when everything’s set up right.
Your Python installation is corrupted or you’ve got conflicting versions messing with each other. That syntax error means node-gyp is running a broken Python interpreter, not just finding the wrong version. I ran into this exact issue when I upgraded from Python 2.7 to 3.8 without properly removing the old version first. Run where python in command prompt to see all Python executables on your system. You’ll probably find multiple entries pointing to different installations. Completely uninstall all Python versions through Control Panel, then do a clean install of Python 3.9 or newer. Don’t forget to check “Add Python to PATH” during installation. This fixed my node-gyp compilation errors when nothing else worked.
I’ve seen this Python path issue before. The syntax error usually means node-gyp found an incompatible Python version or there’s spaces/special characters in your path that’s breaking the parser. Try running npm config set python "C:\Python38\python.exe" to set the Python path explicitly. Check if Python’s working with python --version in your command prompt. If that fails, reinstall Python 3.8 or upgrade to something newer. Also worth clearing npm cache with npm cache clean --force and deleting node_modules before reinstalling - fixes most node-gyp detection problems when compiling native modules.
