Compilar Chromium en Ubuntu 18.04, subcomando ninja fallido.

Intenté escribir un tema de ctf – GoogleCTF2018 Just-In-Time(browser pwn). Intenté compilar chromium en la plataforma de Linux, pero hay un error. Según el archivo build.sh, usé el siguiente comando en terminal. GoogleCTF2018Just-In-Time tema:
https://github.com/google/google-ctf/tree/master/2018/finals/pwn-just-in-time

mkdir chromium
cd chromium
fetch --nohooks chromium
cd src
build/install-build-deps.sh
gclient runhooks
git fetch --tags
git checkout tags/70.0.3538.9
gclient sync
gn gen out/Default
gn args out/Default

en out/Default

use_jumbo_build=true
enable_nacl=false
remove_webcore_debug_symbols=true
use_goma = true
is_debug = false


cd /home/myname/Descargas/v8
git apply ../GoogleCTF2018_Just-In-Time/addition-reducer.patch
cd /home/myname/Descargas/chromium/src/
git apply ../../GoogleCTF2018_Just-In-Time/nosandbox.patch
ninja -C out/Default chrome

Entonces, ocurrió el error …

ninja -C out/Default chrome
directorio : /home/myname/Descargas/chromium/src/

error:
