"在git构建期间无法在@INC中找到ExtUtils/MakeMaker.pm"

Question

我建立git一个相当小的系统(Ubuntu的16.04搬运工图像)不使用包管理器(除wget,xz-utils,make和gcc).因此我按如下方式安装了先决条件:

apt-get update && apt-get install --yes wget xz-utils make gcc
wget http://www.cpan.org/src/5.0/perl-5.26.1.tar.gz && tar xf perl-5.26.1.tar.gz && cd perl-5.26.1 && ./configure.gnu && make -j16 && make install && cd ..
wget https://ftp.gnu.org/pub/gnu/gettext/gettext-0.19.8.1.tar.xz && tar xf gettext-0.19.8.1.tar.xz && cd gettext-0.19.8.1 && ./configure && make -j16 && make install && cd ..
wget https://www.zlib.net/zlib-1.2.11.tar.gz && tar xf zlib-1.2.11.tar.gz && cd zlib-1.2.11 && ./configure && make -j16 && make install && cd ..
cpan install ExtUtils::MakeMaker
wget https://www.kernel.org/pub/software/scm/git/git-2.13.3.tar.gz && tar xf git-2.13.3.tar.gz && cd git-2.13.3 && ./configure && make -j16 && make install && cd ..

但是,make在git源根失败的原因

Can't locate ExtUtils/MakeMaker.pm in @INC (you may need to install the ExtUtils::MakeMaker module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .) at Makefile.PL line 3.
BEGIN failed--compilation aborted at Makefile.PL line 3.

Makefile:83: recipe for target 'perl.mak' failed
make: *** [perl/perl.mak] Error 2
make: *** Waiting for unfinished jobs....
Makefile:1870: recipe for target 'perl/perl.mak' failed

我知道有很多关于Can't locate [module].pm in @INCperl项目的解决方案,我如何告诉CPAN安装所有依赖项？.但是,git使用GNU autotools和可以解决问题的选项可能是从环境变量中读取的,到目前为止我无法弄清楚.

Ubuntu 16.04提供了一个perl但没有cpan命令(这就是我添加perl源安装的原因).perl识别出源安装后,似乎没有使用:

$ which -a perl
/usr/local/bin/perl
/usr/bin/perl
$ which -a cpan
/usr/local/bin/cpan

之后cpan我得到

$ find / -name MakeMaker.pm
/builds/project-0/perl-5.26.1/lib/ExtUtils/MakeMaker.pm
/builds/project-0/perl-5.26.1/cpan/ExtUtils-MakeMaker/lib/ExtUtils/MakeMaker.pm
/root/.cpan/build/ExtUtils-MakeMaker-7.32-0/lib/ExtUtils/MakeMaker.pm
/root/.cpan/build/ExtUtils-MakeMaker-7.32-0/blib/lib/ExtUtils/MakeMaker.pm
/usr/local/lib/perl5/5.26.1/ExtUtils/MakeMaker.pm
/usr/local/lib/perl5/site_perl/5.26.1/ExtUtils/MakeMaker.pm
$ perl -E 'say for @INC'
/usr/local/lib/perl5/site_perl/5.26.1/x86_64-linux
/usr/local/lib/perl5/site_perl/5.26.1
/usr/local/lib/perl5/5.26.1/x86_64-linux
/usr/local/lib/perl5/5.26.1

该设置是从引导脚本中抽象出来的,因此使用包管理器实际上是没有选择的.

您可以使用docker run -i -t ubuntu:latest,以防您关心环境调查.

Answer 1

在CentOS7中,我遇到了这个问题,我发现我应该perl-devel首先安装:

yum install perl-devel

然后重试它.

Answer 2

使用./configure --with-perl=/usr/local/bin/perlforgit有效，但是我不清楚为什么在if/usr/local/bin/perl之前没有被选中。/usr/bin/perlPATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

cpan ExtUtils::MakeMaker添加后就不需要了--with-perl。
