我按照官方网站提供的方法从源码编译，步骤如下：

git clone https://github.com/PaddlePaddle/Paddle.git
cd Paddle
docker build -t paddle:dev .
docker run -it -v $PWD:/paddle -e "WITH_GPU=OFF" -e "WITH_TESTING=OFF" paddle:dev /bin/bash
bash -x /paddle/paddle/scripts/docker/build.sh

在最后一步使用脚本build.sh编译paddlepaddle时总是报错：

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

并且尝试重新编译，有时会报其他错误如下：

在一周前通过这个方法成功编译过，但可能是这几天同步了https://github.com/PaddlePaddle/Paddle.git 最新代码，导致编译失败，请问是什么问题呢
