在Linux上為VS Code終端設(shè)置環(huán)境變量的方法有兩個：一是使用terminal.integrated.env.linux配置項定義僅限VS Code使用的變量；二是修改shell配置文件以全局生效。1. 在VS Code中，通過設(shè)置terminal.integrated.env.linux字段添加變量如"MY_VAR": "my_value"，此方式僅影響VS Code終端；2. 修改如~/.bashrc或~/.zshrc等shell配置文件并加入export MY_VAR="my_value"語句，此方式影響所有終端；注意VS Code通常啟動非登錄shell，因此應(yīng)確保變量定義位于非登錄shell加載的文件中，如~/.bashrc，必要時可在其他配置文件中調(diào)用該文件；測試當前shell類型可通過命令echo $0確認，若輸出以-開頭則為登錄shell；更改配置后需重啟終端以應(yīng)用新設(shè)置。

Setting environment variables for the terminal in VS Code on Linux is actually pretty straightforward once you know where to look. The key is understanding that VS Code uses your system’s shell configuration files by default, but it also gives you control through its own settings.

Use terminal.integrated.env.linux in Settings

VS Code allows you to define custom environment variables specifically for the integrated terminal using the terminal.integrated.env.linux setting. This is useful if you want certain variables set only when working inside VS Code and not globally on your system.

To use this:

• Open your VS Code settings (you can press Ctrl ,)
• Search for “terminal integrated env linux”
• Click “Edit in settings.json”

Then add something like:

"terminal.integrated.env.linux": {
    "MY_VAR": "my_value",
    "DEBUG_LEVEL": "3"
}

These variables will be available every time you open a new terminal window inside VS Code.

Modify Shell Configuration Files

If you want environment variables to be available across all terminals — including the one in VS Code — you should modify your shell's configuration file. For example:

• If you're using Bash: edit ~/.bashrc or ~/.bash_profile
• If you're using Zsh: edit ~/.zshrc

Just add lines like this:

export MY_VAR="my_value"
export PATH="/some/custom/path:$PATH"

After saving, run source ~/.bashrc (or the appropriate file) to apply changes immediately.

This method affects all terminals, not just VS Code, so it's more global.

Be Aware of Login vs Non-login Shells

One thing that often trips people up is that VS Code usually starts a non-login shell. That means it might not load all the same configuration files as when you open a regular terminal.

For example:

• A login shell loads ~/.bash_profile, ~/.profile, etc.
• A non-login shell typically loads ~/.bashrc (in Bash)

So if you're putting environment variables in a file that doesn’t get loaded by default in a non-login shell, they won’t show up in VS Code.

To make sure your variables are always loaded:

• Put them in ~/.bashrc (or equivalent)
• Or source that file from another config file like .bash_profile

You can test what kind of shell you’re in by running:

echo $0

If it starts with a -, it’s a login shell.

Final Notes

You don't need any special extensions or tools — just a bit of setup in either VS Code settings or your shell config. And remember, if you're testing changes, always open a new terminal tab after editing config files to see the effect.

基本上就這些。
