未定义的子程序＆amp; main :: vars调用

Question

我正在尝试使用git检出存储库。我已经在.cfg文件中指定了git repo路径和所有目录路径。现在我尝试通过获取值作为哈希来访问.cfg文件中的文件夹路径和repo路径。我完全根据我对Perl的理解验证了我的代码。但过去两天我真的厌倦了这一点。我得到的错误是

Undefined subroutine &main::vars called at Create_UnitTesting_Environment_and_Ru
n_UnitTestSuites.pl line 28.

有时喜欢这个

Can't call method "vars" on an undefined value at Create_UnitTesting_Environment
_and_Run_UnitTestSuites.pl line 28.

我无法弄清楚 - 我错过了全球宣布的内容。请有人帮我解决这个问题。
