请问@INC的perl6等值是什么？

Question

我走了

export PERL6LIB="/GitHub/perl6-Units/lib"

然后

echo $PERL6LIB
/GitHub/perl6-Units/lib

但是当我运行perl6 t/01-basic.t时

use v6;

use Test;

plan 3;

lives-ok {
    use Units <m>;
    ok @Units::UNITS.elems > 0;
    ok (0m).defined;
} 

done-testing;

我还是有个错误

===SORRY!===
Could not find Units at line 8 in:
    /Users/--me--/.perl6
    /usr/local/Cellar/rakudo-star/2018.01/share/perl6/site
    /usr/local/Cellar/rakudo-star/2018.01/share/perl6/vendor
    /usr/local/Cellar/rakudo-star/2018.01/share/perl6
    CompUnit::Repository::AbsolutePath<140707489084448>
    CompUnit::Repository::NQP<140707463117264>
    CompUnit::Repository::Perl5<140707463117304>

在Perl 5中，我会使用print "@INC";查看在抛出错误之前搜索哪些路径。使用say flat $*REPO.repo-chain.map(*.loaded);不是在加载之前，就是在抛出异常之后。

任何帮助都将是非常感激的--或者是关于在~/.perl6中添加什么的提示，因为我也无法获得一个符号链接来工作。

Answer 1

错误消息本身告诉您可用的库路径是什么。您无法打印它们，因为您期望在编译时错误之前发生运行时操作( say ) --您可以在编译时打印出$*REPO，但异常已经显示了您想要的内容。

$ PERL6LIB="/GitHub/perl6-Units/lib" perl6 -e 'BEGIN say $*REPO.repo-chain; use Foo;'
(file#/GitHub/perl6-Units/lib inst#/Users/ugexe/.perl6 inst#/Users/ugexe/.rakudobrew/moar-2018.08/install/share/perl6/site inst#/Users/ugexe/.rakudobrew/moar-2018.08/install/share/perl6/vendor inst#/Users/ugexe/.rakudobrew/moar-2018.08/install/share/perl6 ap# nqp# perl5#)

您可以看到/GitHub/perl6-Units/lib显示在可用路径中，这与您的示例不同。我会问您的shell/env是否确实设置正确。
