如何快速修改Shell环境变量？

Question

使用时如何访问shell env var之一Process？如果我environment用来设置它们，它将更改所有的环境变量。

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

Answer 1

您可能会在ProcessInfo.processInfo.environment自定义路径（或所需的任何路径）上附加（继承的环境）来解决它：

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