我正在尝试通过执行以下命令在AWS上的Ubuntu 14.04上构建V8。这些是来自Makefile的行，这就是语法异常的原因。
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git depot_tools
(export PATH=$(shell pwd)/depot_tools:$$PATH && fetch v8)
(cd v8 && git checkout -b 3.31.30 --quiet)
(export PATH=$(shell pwd)/depot_tools:$$PATH && cd v8 && gclient sync)
(export PATH=$(shell pwd)/depot_tools:$$PATH && cd v8 && make x64.release -j8 library=shared)
但是，在第2行（运行fetch v8）上，进程失败，并显示以下错误消息。

这个过程在运行Ubuntu 14.04的本地虚拟机上运行正常。构建无法在运行在AWS EC2上的实例上运行，该实例也运行Ubuntu 14.04，其中构建在JetBrains TeamCity下执行。
关键错误似乎是这一行：
Error: Command download_from_google_storage --no_resume --platform=linux* --no_auth --bucket chromium-clang-format -s v8/buildtools/linux64/clang-format.sha1 returned non-zero exit status 1 in /var/teamcity/work/efeb1dfa99775e78/libs/3rdParty/v8
试图告诉我这是什么错误？我究竟做错了什么？ Google透露了a similar problem的其他用户，但没有解决方案。

我在这里遇到了与arch linux（64）相同的错误
在我的情况下，在制作32位版本时可以忽略此错误。 - ＆GT;制作ia32.release
你可以尝试添加make ia32.release GYPFLAGS = -Dclang = 0如果clang出现错误
希望有所帮助！
干杯

在这种情况下，我的持续集成/ teamcity用户没有“home”目录。我按如下方式定义了一个，问题得到了解决。
sudo mkdir -p /var/teamcity/home
sudo usermod --home /var/teamcity/home teamcity
sudo chown -R teamcity:teamcity /var/teamcity
