當我執行命令，在本網頁https://webrtc.org/native-code/android/無法在Ubuntu實例
提供跟着步驟設置的WebRTC android原生代碼「忍者-C輸出/調試AppRTCMobile」我得到了如下回應
ninja: Entering directory `out/Debug'
ninja: fatal: chdir to 'out/Debug' - No such file or directory
我卡在這裏，需要幫助繼續執行下一步完成代碼設置。
Ubuntu的版本 - 16.04.2
我都遵循同樣的程序再次設置代碼。這一次，我得到了一個新的錯誤
步驟：
-> fetch --nohooks webrtc_android
-> gclient sync
-> gn gen out/Debug --args='target_os="android" target_cpu="arm"'
-> ninja -C out/Debug
ninja: Entering directory `out/Debug'

有人請幫我解決這個問題。
