build_native.py失败并出现错误:为项目构建动态库..失败

Question

我已经安装了cocos2d-x 3.0并尝试构建一个Android版本但是当我运行./build_native.py时,它失败并出现错误

File "./build_native.py", line 89, in do_build
raise Exception("Build dynamic library for project [ " + app_android_root + " ] fails!")
Exception: Build dynamic library for project [ /Users/hoangha/Desktop/Enigma/cocos2d-x-3.0/projects/2048-enhanced-version/source/proj.android ] fails!

我已经阅读了build_native.py中的第89行

if os.system(command) != 0:
    raise Exception("Build dynamic library for project [ " + app_android_root + " ] fails!")

但是我不理解python中的命令os.system(命令),所以任何人都可以帮我解决这个错误.
