我使用安装了两个版本的 Perl --as(仅用主编号命名版本)

  • 5.20.0安装为5.20
  • 5.20.0螺纹安装为5.20t

这是的输出perlbrew list

* 5.20 (5.20.0)
  5.20t (5.20.0)

然后我将 Perl 升级为5.20.1使用

$ perlbrew upgrade-perl
Upgrading 5.20 to 5.20.1
Installing /Users/corti/perl5/perlbrew/build/perl-5.20.1 into ~/perl5/perlbrew/perls/5.20

This could take a while. You can run the following command on another shell to track the status:

  tail -f ~/perl5/perlbrew/build.perl-5.20.1.log

5.20 is successfully installed.

Perl 似乎已正确升级(v5.20.1):

$ perl -version

This is perl 5, version 20, subversion 1 (v5.20.1) built for darwin-2level

perlbrew list不识别新版本,调用perlbrew upgrade-perl再次升级

$ perlbrew list
* 5.20 (5.20.0)
  5.20t (5.20.0)

为什么不perlbrew识别更新?

因为 perlbrew 检查是否存在一个名为

perls/*/.version

并使用其内容来确定安装了哪个版本的 Perl。如果它没有找到该文件,它会回退到运行 perl 可执行文件

perls/*/bin/perl

确定安装的版本并创建 .version 文件。

upgrade-perl 命令无法更新文件,因此后续运行无法正确检测到安装的版本。我已提交错误报告
