问题描述

使用Process时如何访问其中一个shell env var?如果我使用environment进行设置，它将更改所有的环境变量.

How can I access one of the shell env vars when using Process? If I use environment to set them, it will change all of the env vars.

let task = Process()
// How do I modify PATH only instead of setting the whole dictionary
task.environment = ["PATH": "/usr/local/bin"]

推荐答案

您可能会解决此问题，并将其添加到ProcessInfo.processInfo.environment(继承的环境)您的自定义路径(或所需的任何路径)上:

You might solve it appending on ProcessInfo.processInfo.environment (the inherited environment) your custom path (or whatever you need):

let task = Process()
var environment =  ProcessInfo.processInfo.environment
environment["PATH"] = "/usr/local/bin"
task.environment = environment
print(task.environment ?? "")
