How to set an (environment) variable in the build script in Gitlab CI?
提问by static
I have a dummy build script in the Gitlab CI:
我有一个虚拟构建脚本Gitlab CI：
pwd
ci_app_path=$(pwd)
echo "INFO: current directory: $ci_app_path"
and I get this output when the system start the build process:
当系统开始构建过程时，我得到了这个输出：
pwd
/home/kai/gitlab-runners/gitlab-ci-runner/tmp/builds/project-1
ci_app_path=$(pwd)
echo "INFO: current directory: $ci_app_path"
INFO: current directory:
so the variable was not set (or was set only for that line: as I know each line executed separately)
所以未设置变量（或仅为该行设置：据我所知，每行单独执行）
I heard about push/pop mechanism to reach the functionality I desired, but could not find any details, how to implement that.
我听说过推送/弹出机制来达到我想要的功能，但找不到任何细节，如何实现它。
Update:
更新：
as I thought, each line is going executed separately. So the variable scope is only one line, where it is defined:
正如我所想，每一行都将单独执行。所以变量作用域只有一行，它的定义是：
script:
脚本：
pwd
ci_app_path=$(pwd) && echo "INFO: current directory: $ci_app_path"
output:
输出：
pwd
/home/devuser/gitlab-runners/gitlab-ci-runner/tmp/builds/project-1
ci_app_path=$(pwd) && echo "INFO: current directory: $ci_app_path"
INFO: current directory: /home/kai/gitlab-runners/gitlab-ci-runner/tmp/builds/project-1
I don't think that writing the whole script as a one-liner is a good idea/practice.
我不认为将整个脚本写成一行代码是一个好主意/做法。

actually I wonder why the whole build script must contain no empty lines?, otherwise it returns:
实际上我想知道为什么整个构建脚本不能包含空行？，否则返回：
No such file or directory
and a build fails on this place
并且在这个地方构建失败

Gitlab CI just plays shell commands so do what you do in *sh:
Gitlab CI 只是播放 shell 命令，所以做你在 *sh 中所做的：
export ci_app_path=$(pwd)
echo "INFO: current directory: $ci_app_path"

By the time Gitlab-CI folks fix it, you may create a Makefile and export variables inside it and in Gitlab-CI pass the variables, for example
到 Gitlab-CI 人员修复它时，您可以创建一个 Makefile 并在其中导出变量并在 Gitlab-CI 中传递变量，例如
PWD=$PWD make
PWD=$PWD 制作
Makefile starts with a: export GOPATH=$(PWD)
Makefile 以一个开头：export GOPATH=$(PWD)
