perl - 为什么安装 Scrappy 时 CPAN 安装失败？

Question

我知道它缺少依赖项，但我认为 CPAN 会自动安装所有依赖模块。这是错误:

然后我尝试单独安装一个依赖模块:

cpan[2]> install PadWalker
Running install for module 'PadWalker'
Running make for R/RO/ROBIN/PadWalker-1.96.tar.gz
  Has already been unwrapped into directory /root/.cpan/build/PadWalker-1.96-n6C9km
Could not make: Unknown error
Running make test
  Can't test without successful make
Running make install
  Make had returned bad status, install seems impossible

有人能指出我正确的方向吗？我是 root，到目前为止它是最新的 Ubuntu 12.04.1。

可以使用 CPAN 安装 Scrappy。在我的情况下，只有 Moose 必须被强制(失败的 1/382 测试程序。0/18150 子测试失败)。

cpan[6]> force install Moose
[...]

cpan[7]> install Scrappy
Running install for module 'Scrappy'
Running make for A/AW/AWNCORP/Scrappy-0.94112090.tar.gz

  AWNCORP/Scrappy-0.94112090.tar.gz
  /usr/bin/make install  -- OK

您应该尝试手动安装 PadWalker 以找出背后的原因 Could not make: Unknown error .

就我而言，PadWalker 可以从 ~/.cpan/build/PadWalker-1.96-XW0Mq2 安装。如下:

perl Makefile.PL

Checking if your kit is complete...
Looks good
Writing Makefile for PadWalker
Writing MYMETA.yml

制作

cp PadWalker.pm blib/lib/PadWalker.pm
/usr/bin/perl /usr/share/perl/5.14/ExtUtils/xsubpp  -typemap /usr/share/perl/5.14/ExtUtils/typemap  PadWalker.xs > PadWalker.xsc && mv PadWalker.xsc PadWalker.c

chmod 755 blib/arch/auto/PadWalker/PadWalker.so
cp PadWalker.bs blib/arch/auto/PadWalker/PadWalker.bs
chmod 644 blib/arch/auto/PadWalker/PadWalker.bs

做测试

Result: PASS
