Swift
/// 运行脚本
func runScript() {
// Swift调用终端用Process类,这里先创建一个对象
let pro = Process()
// 指定编译器
pro.launchPath = "/bin/bash"
// 设置要执行的语句,如果是有多条命令,用;隔开
// 注意!因为命令是用""包在字符串里的,所以命令中有"时要用\"做转义
pro.arguments = ["-c", "pwd; which python; python -V; python test01.py; say start; pwd; which python3; python3 -V; python3 test03.py; python3 TestWYY.py; say over"]
// 启动
pro.launch()
pro.waitUntilExit()
print("脚本执行完毕")
}
这里有个遗留问题,Mac系统(10.13.4)自带的python版本是2.7.10,如果python3是用HomeBrew安装的,那么python3 xxxx.py会报错command not found,个人推测可能是因为Xcode默认调用的是系统自带的python2.7.10。
