# Troubleshooting

# Windows

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
  • Install Python 2.7 (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.
