The Ultimate Development Environment Setup Tool for Windows

DevEnvx CLI is a zero-install, cross-language setup tool available directly via npx.
It lets you configure full development environments (Python, Java, C++, and more) from the terminal — no downloads, no GUIs, no extra setup.
Everything happens via trusted PowerShell scripts under the hood, but you only run one command:

npx devenvx

That’s it. No global installation. No browser. No configuration.

✨ Why DevEnvx?

• Powered by npm — Instantly accessible via the world’s most trusted package registry — no installs, no browser, just run.
• Truly One-Line Setup — From nothing to a fully configured environment in seconds
• Zero Browser Required — Everything happens in your terminal
• Windows-Native Integration — Purpose-built for Windows using PowerShell scripts
• Clean, Fast, & Reliable — Optimized installers with intelligent validation
• Multiple Language Support — Set up C++, Java, Python, and more with one interface

🚀 Get Started in Seconds

1. Run DevEnvx directly:

npx devenvx

▸ Prefer using it globally? Install once with:

npm install -g devenvx

Then run it anytime with:

devenvx

2. Set up your desired programming language:

npx devenvx install python

▸ Using the global install? Run:

devenvx install python

3. Start coding instantly

Your environment is ready to use right away — no terminal restart needed.

python --version

ℹ️ Note:
The first time you run npx devenvx, npm may ask:
Need to install the following packages: devenvx... Ok to proceed? (y)
Just type y — from next time, it runs instantly without prompts.

🔄 How It Works

DevEnvx uses Node.js and PowerShell to create a seamless installation experience:

1. The CLI parses your command and identifies the language(s) to install
2. It runs specialized PowerShell scripts with elevated permissions to:
   • Download official installers directly from trusted sources
   • Execute installations with silent flags for zero-interaction setup
   • Configure system PATH and environment variables
   • Verify the installation with real compilation tests
3. You get a fully functional development environment without leaving your terminal

🏆 What Makes DevEnvx One-of-a-Kind

• No Browser Required — Unlike other tools that open your browser or require manual downloads, DevEnvx handles everything within the terminal
• Zero Manual Intervention — No clicking through installers or manually configuring environment variables
• First-Class Windows Support — Built specifically for Windows, not a Linux tool poorly adapted to Windows
• Intelligent Recovery — Automatically detects and fixes broken or partial installations
• Actual Compilation Testing — Verifies installations by compiling and running real code

📚 PowerShell Documentation

To understand how DevEnvx works under the hood, including all PowerShell flags, behaviors, and scripting logic used in our installers and uninstallers:

🔗 docs/powershell-notes.md

This guide is beginner-friendly and explains every flag and concept used in the project — a must-read if you're exploring or contributing.

🧠 PowerShell Troubleshooting

If you see an error like this when running npx devenvx:

npx : File C:\Program Files\nodejs\npx.ps1 cannot be loaded because running scripts is disabled on this system.

It means your system's PowerShell script execution policy is restricted.

✅ Fix: Allow PowerShell Scripts Permanently (Safe)

To allow trusted scripts to run in all PowerShell sessions for your user account, run:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser -Force

This is a safe and permanent fix that enables locally created or signed scripts — without affecting system-wide security.
