VS Code运行代码显示路径且速度慢，如何优化？

Hey there! Let's tackle your VS Code problems step by step — I've been where you are, switching from Sublime/Atom and wondering why VS Code feels sluggish for simple scripts.

Why are you seeing those path messages in the output? #

That long string starting with user_dev@DESKTOP-131452 MINGW64 ~/Documents/VSCODE/Python/BeautifulSoup $ cd "C:\Users\user_dev\Documents\VSCODE\Python\BeautifulSoup" ; env "PYTHONIOENCO... isn't coming from your code — it's VS Code's default way of running your script in the integrated terminal.

Here's what's happening behind the scenes: VS Code first navigates to the directory where your Python file lives (that's the cd command part), then sets up some environment variables (the env "PYTHONIOENCO..." bit) before finally running your script. The terminal is just echoing the full command chain it's executing, which is why you see all that path and environment stuff.

Is this causing the 5-second delay? #

Short answer: No, those printed paths themselves aren't slowing things down. The 5-second wait is almost certainly coming from somewhere else. Common culprits include:

• Slow terminal startup (MINGW64 can be slower to spin up than Windows' native terminals like PowerShell or Windows Terminal)
• VS Code loading unnecessary plugins in the background
• Python itself taking time to initialize (especially if you have a lot of installed packages or an older Python version)
• The extra overhead from VS Code spawning the terminal process with that full command chain

Optimization fixes to speed things up #

Try these tweaks to get your "Hello World" running in a blink:

1. Switch to a faster terminal #

MINGW64 adds extra layers that can slow down execution. Switch to Windows Terminal or PowerShell instead:

• Open VS Code settings (Ctrl+, or Cmd+, on Mac)
• Search for terminal.integrated.defaultProfile.windows
• Select either "Windows Terminal" or "PowerShell" from the dropdown
• Restart VS Code to apply the change

2. Use a launch configuration instead of terminal execution #

Setting up a launch.json lets you run your script directly without the extra terminal command noise — and often faster:

• Open your Python file, then click the "Run and Debug" tab (Ctrl+Shift+D)
• Click "create a launch.json file" and select "Python" as the environment
• Replace the default config with something like this:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "internalConsole", // Uses VS Code's debug console instead of terminal
            "justMyCode": true
        }
    ]
}

Now when you hit F5 to run, you'll only see your script's output in the debug console — no extra path clutter, and faster execution.

3. Disable unused VS Code extensions #

Too many running extensions can hog resources. Go to the Extensions panel (Ctrl+Shift+X) and disable any plugins you don't actively use — especially ones for languages you don't code in, or niche tools you rarely need. Keep only essentials like the official Python extension.

4. Update your Python version #

Older Python releases (like 3.7 or earlier) can have slower startup times. Grab the latest stable version, make sure it's set as the default interpreter in VS Code (Ctrl+Shift+P > "Python: Select Interpreter"), and test again.

5. Tweak terminal execution settings #

If you prefer using the terminal, you can make VS Code skip the directory change step:

• Open settings, search for python.terminal.executeInFileDir
• Uncheck the box — this will run your script from the terminal's current working directory instead of switching to the file's folder, eliminating the cd command in your output.
