facebook - 无法从 Github 构建 Facebooks HHVM(git submodule init)

Question

当我运行这些步骤时:

mkdir dev
cd dev
git clone git://github.com/facebook/hhvm.git
cd hhvm
git submodule init
export CMAKE_PREFIX_PATH=`pwd`/..
export HPHP_HOME=`pwd`
cd ..

我卡在 git submodule init 我收到错误:Submodule 'hphp/submodules/folly' () registered for path 'hphp/submodules/folly'

我不知道这是什么意思，看起来不像是 fatal error ...

更新:git submodule sync 确实同步了 php/submodules/folly 但仍然是同样的错误...

Answer 1

我会尝试:

git submodule update --init --recursive

并确保“Submodule 'xxx' registered for path 'yyy'”确实是一个错误消息:它看起来像是一个的标准答案git submodule init 命令。
来自git submodule book page :

The rack directory is there, but empty.
You must run two commands:

• git submodule init 初始化你的本地配置文件，和

• git submodule update 从该项目中获取所有数据并检查您的 super 项目中列出的适当提交:

  $ git submodule init
  Submodule 'rack' (git://github.com/chneukirchen/rack.git) registered for path 'rack'
  $ git submodule update
  Initialized empty Git repository in /opt/myproject/rack/.git/

  Submodule path 'rack': checked out '08d709f78b8c5b0fbeb7821e37fa53e69afcf433'
  

我更喜欢只运行一个命令:

git submodule update --init
