If you are experiencing issues running n8n with the typical flow of:
npx n8n
# Requirements
Please ensure that you have the following requirements fulfilled:
- Install latest version of NodeJS (opens new window)
- Install Python 2.7 (opens new window) (It is okay to have multiple versions installed on the machine)
- Windows SDK
- C++ Desktop Development Tools
- Windows Build Tools
# Install build tools
If you haven't satisfied the above, follow this procedure through your PowerShell (run with administrative privileges). This command installs the build tools, windows SDK and the C++ development tools in one package.
npm install --global --production windows-build-tools
# Configure npm to use Python version 2.7
npm config set python python2.7
# Configure npm to use correct msvs version
npm config set msvs_version 2017 --global
# Lesser known issues:
# mmmagic npm package when using MSbuild tools with Visual Studio
While installing this package, node-gyp is run and it might fail to install it with an error appearing in the ballpark of:
gyp ERR! stack Error: spawn C:\Program Files (x86)\Microsoft Visual Studio\2019\**Enterprise**\MSBuild\Current\Bin\MSBuild.exe ENOENT
It is seeking the MSBuild.exe in a directory that does not exist. If you are using Visual Studio Community or vice versa, you can change the path of MSBuild with command:
npm config set msbuild_path "C:\Program Files (x86)\Microsoft Visual Studio\2019\**Community**\MSBuild\Current\Bin\MSBuild.exe"
Attempt to install package again after running the command above.
