python执行unity打包

由于打包机并没有图形界面，在满屏的日志里面找错误又比较繁琐。所以需要捕获日志的错误在最后显示
使用管道执行unityeditor命名空间下的打包方法。指定-logFile参数日志输出到stdout
返回非0值给shell捕获返回

import os
import subprocess

def cmd(command):
    p= subprocess.Popen(command,shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    errLines=[]
    while p.poll() is None:
            line = p.stdout.readline()
            line = line.strip().decode("utf-8")
            print(line)
            if ": error" in line or "Exception:" in line:
                errLines.append(line)
                
    if p.returncode == 0:
        print('success')
    else:
        print('fail')
        for line in errLines:
            print(line)
        exit(1)

def main():
    unityPath = "F:/unity/2019.4.28f1c1/Editor/Unity.exe"
    projectPath = os.getcwd()
    method = "BuildTool.BuildSetting"
    cmd("{} -quit -batchmode -projectPath {} -executeMethod {} -logFile -nographics"
        .format(unityPath,projectPath,method))

if __name__ == "__main__":
    main()

最后把错误打印出来。方便查找原因
