CPANM 路径未正确配置

Question

提取新的 Strawberry Perl 副本后，我在 CPANM 中遇到错误。

C:\portable_perl>cpanm --self-upgrade
You are running cpanm from the path where your current perl won't install execut
ables to.
Because of that, cpanm --self-upgrade won't upgrade the version of cpanm you're
running.

  cpanm path   : C:\portable_perl\perl\bin/cpanm
  Install path : C:\portable_perl\perl\site\bin

It means you either installed cpanm globally with system perl, or use distro pac
kages such
as rpm or apt-get, and you have to use them again to upgrade cpanm.

C:\portable_perl>

安装App::cpanminus 后，我得到一个稍微不同的错误。

C:\portable_perl>cpanm --self-upgrade
You are running cpanm from the path where your current perl won't install executables to.
Because of that, cpanm --self-upgrade won't upgrade the version of cpanm you're running.

  cpanm path   : C:\portable_perl\perl\site\bin/cpanm
  Install path : C:\portable_perl\perl\site\bin

It means you either installed cpanm globally with system perl, or use distro packages such
as rpm or apt-get, and you have to use them again to upgrade cpanm.

C:\portable_perl>

有没有办法设置路径？或者以不同的方式安装 CPANM？如果这很重要，我会在 Windows 7 x64 上运行它。

Answer 1

脚本可以

$0 !~ /^$install_base/

$0 在哪里

C:\portable_perl\perl\site\bin/cpanm

而$install_base 是

C:\portable_perl\perl\site\bin

它不需要反斜杠。 \po、\pe、\s 和 \b 在正则表达式模式中都有特殊含义。这是cpanm 中的一个错误。
