我想让 CI Runner 使用 G++ 4.8 进行 npm 安装步骤。我在搞乱 .gitlab-ci.yml - 这是我当前的版本：
before_script:
- . /etc/profile.d/_environment.sh
- . /etc/profile.d/runner.sh
- nvm use v5.3.0
build:
script:
- scl enable devtoolset-2 bash
- g++ --version
- npm install
- gulp build
tags:
- shell
style-analysis:
script:
- gulp style
tags:
- shell
不幸的是，我的构建失败了。步骤“scl enable devtoolset-2 bash”应该切换到 G++ 4.8，当我直接在控制台上运行它时它会这样做。下一行“g++ --version”用于捕获版本，以便我可以调试这里发生的事情。它不是显示版本 4.8 而是 4.4。这将导致我的构建失败。这是输出的“头”

看起来好像来自一个步骤的值没有结转到下一步。例如 - 就好像它们发生在自己的外壳中一样。
