    # This will NOT work.  These two `run` steps are written
    # as different scripts and run by different shells, so
    # the `FOO` variable will NOT persist between them.
    # 这个方式行不通。这两个 `run` 会被写入
    # 不同的脚本中，而且运行在不同的shell环境下，所以
    # `FOO` 变量不会在它们之间持续存在。

    # 这将在第一个 `run` 脚本中设置 FOO 环境变量值，
    # 然后指示 Github Actions 使在接下来的 `run` step 中这个环境变量可用。
