在干净的环境中启动终端＃

VSCode中的Integrated Terminal的行为始终与普通终端有些不同，尤其是在Linux和macOS上。原因是环境始终是从VSCode的窗口（实例）继承的，并且VS VS /电子相关的环境变量已删除，而通常会从Dock / Start菜单中启动普通终端并使用系统环境。在某些情况下这可能会导致问题，例如Python虚拟环境由于使用$PATH变量的方式而损坏。

有一个新的预览选项，terminal.integrated.inheritEnv当false时,终端不使用VS Code的环境。

而是，取决于平台，它将执行以下操作：

• Linux ：获取并使用VS Code的“主进程”的父进程的环境。
• macOS ：从当前环境中 提取 一些重要的环境变量，仅包含它们。最终，我们希望macOS的行为与Linux相同，但是当前获取环境存在问题。
• Windows ：当前此设置不影响Windows。

设置inheritEnv为的主要可见结果false是$SHLVL（shell级别）现在应该为1，并且$PATH不应包含重复路径，前提是启动脚本没有故意包含它们。

为默认值terminal.integrated.inheritEnv是true，这是以前的行为，但VSCode可能在未来会值切换到false。

The Integrated Terminal in VS Code has always acted a little differently to normal terminals, particularly on Linux and macOS. The reason is that the environment was always inherited from VS Code’s window (instance) and VS Code/Electron-related environment variables were removed, whereas a normal terminal would typically be launched from the Dock/Start menu and use the system environment. This could cause issues in certain scenarios, for example Python virtual environments were broken because of how they use the $PATH variable.
There’s a new preview option, terminal.integrated.inheritEnv, that when
false causes the terminal to not use VS Code’s environment.
Instead, depending on the platform, it will do the following:

• Linux : Fetch and use the environment of the parent process of VS Code’s “main process”.
• macOS : Pull a handful of important environment variables off the current environment and only include them. Eventually we would like macOS to behave the same as Linux but there are currently issues with fetching environments.
• Windows : Currently this setting does not affect Windows.
  The main visible result of setting inheritEnv to false is that $SHLVL (shell level) should now be 1 and $PATH should not include duplicate paths, provided your launch scripts don’t intentionally include them.
  The default value for terminal.integrated.inheritEnv is true, which is the previous behavior, but we will probably switch the value to false in the future.
