Swift CLI - $PATH is incomplete

Question

I'm building a CLI tool as a Swift Package. Part of the process requires me to invoke some processes (such as gsutil). When I try to invoke those, I always end up with *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'launch path not accessible'

Some further analysis revealed that regular commands suchs as pwd or which work just fine. As pictured below, if I try to echo $PATH, I get an incomplete result.

The value of $PATH while running the project directly

/Applications/Xcode-beta.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin\n

is completely different from my actual $PATH variable:

echo $PATH
/Users/skwiggs/google-cloud-sdk/bin:/Users/skwiggs/.npm-global/bin:/Users/skwiggs/.rbenv/bin:/Users/skwiggs/.rbenv/shims:/Users/skwiggs/google-cloud-sdk/bin:/Users/skwiggs/.npm-global/bin:/Users/skwiggs/.rbenv/bin:/Users/skwiggs/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/share/dotnet:~/.dotnet/tools:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands

How can I ensure that my env variables are correctly set while debugging my CLI tool?

直接从 shell 运行该工具将向其传递预期$PATH值，因此此问题仅在调试时发生。

如果您想使用正确的$PATH值调试程序，您可以在活动方案中添加环境变量。该变量仅在调试时使用，因此可以安全地覆盖它（从 shell 调用产品时它将被忽略）。

1. 打开终端
2. 跑步echo $PATH
3. 复制输出

然后，打开XCode

方案->编辑方案->运行->环境变量->添加。

名称 PATH 值 <paste the value from terminal>

构建并运行，您现在可以像从 shell 调用项目一样进行调试。

（请记住，您必须对需要此行为的每个新项目执行此操作，并且对您的意愿的任何更改都$PATH必须对您的项目进行改造）
