我正在尝试从 Mac Ports 安装端口，但似乎它最后p5-app-ack没有创建二进制文件：/opt/local/bin/ack

$ which ack
答案1
你可以试试：
sudo cpan App::Ack
/opt/local/bin/ack它会安装 ack 并使用您机器上的默认 perl 环境配置二进制文件。安装后，您只需运行“ack pattern”即可。
答案2
包 p5-app-ack 是一个存根包，它安装一个包含与您安装的 perl 版本匹配的实际可执行文件的包。
shiny:~ fl$ port deps p5-app-ack
Full Name: p5-app-ack @1.960.0_1
Library Dependencies: p5.12-app-ack
由于您已经安装了 perl5.12，您将找到存根包和包含二进制文件的包：
shiny:~ fl$ port list p5*-app-ack
p5-app-ack @1.960.0 perl/p5-app-ack
p5.12-app-ack @1.960.0 perl/p5-app-ack
并且程序将被安装以匹配 Perl 环境：
shiny:~ fl$ port contents p5.12-app-ack
Port p5.12-app-ack contains:
/opt/local/bin/ack-5.12
/opt/local/lib/perl5/vendor_perl/5.12.4/App/Ack.pm
/opt/local/lib/perl5/vendor_perl/5.12.4/App/Ack/Plugin.pm
/opt/local/lib/perl5/vendor_perl/5.12.4/App/Ack/Plugin/Basic.pm
/opt/local/lib/perl5/vendor_perl/5.12.4/App/Ack/Repository.pm
/opt/local/lib/perl5/vendor_perl/5.12.4/App/Ack/Resource.pm
/opt/local/lib/perl5/vendor_perl/5.12.4/darwin-thread-multi-2level/auto/ack/.packlist
/opt/local/libexec/perl5.12/ack
/opt/local/share/perl5.12/man/man1/ack.1pm
你可以添加/opt/local/libexec/perl5.12到你的$PATH，或者/opt/local/libexec/perl5.12/ack在你的$PATH
