perl DBI 模块安装出错

Question

perl DBI 模块安装出错。

使用 -Dinstallprefix 选项在非标准位置安装了 perl 5.32.1

./Configure -Dinstallprefix=/test/user/home/perl -des
make
make test
make install

/test/user/home/perl/bin/perl -version
This is perl 5, version 32, subversion 1 (v5.32.1) built for x86_64-linux

设置 PERL5LIB 环境变量

export PERL5LIB="/test/user/home/perl/lib/5.32.1:/test/user/home/perl/lib/site_perl/5.32.1:/test/user/home/perl/lib/5.32.1/x86_64-linux"

which perl
/test/user/home/perl/bin/perl

已下载 DBI-1.643 压缩包，在提取执行 Makefile.PL 后失败

perl Makefile.PL

发现不存在的路径引用自@INC

perl -e "print \"@INC\""

/test/user/home/perl/lib/5.32.1 /test/user/home/perl/lib/site_perl/5.32.1 /test/user/home/perl/lib/5.32.1/x86_64-linux
/perl/lib/site_perl/5.32.1/x86_64-linux /perl/lib/site_perl/5.32.1 /perl/lib/5.32.1/x86_64-linux /perl/lib/5.32.1

有人可以指导我从@INC 获得这些不存在的路径吗

/perl/lib/site_perl/5.32.1/x86_64-linux /perl/lib/site_perl/5.32.1 /perl/lib/5.32.1/x86_64-linux /perl/lib/5.32.1

有什么方法可以限制@INC 附加不存在的路径吗？

Answer 1

我想你只需要 -Dprefix=/...。还有其他事情也需要在正确的地方结束。你不需要设置 PERL5LIB，因为 perl 应该使用你的前缀作为它的默认 @INC。你的 perl -V 显示什么？

有一个installprefix，但它的目的是在一台机器上编译并在另一台机器上安装。但是，INSTALL 文档也建议不要使用它。这就是你想要做的吗？

至于其他目录，INSTALL 文档描述了 @INC 中出现的各种目录。

Answer 2

谢谢@brian 为我指明了正确的方向。

以下是@INC 包含不存在目录的根本原因。

最后一次在 perl 安装过程中至少有一次我运行按照命令

./Configure -des -Dprefix=/perl

Use relocatable @INC? [n]
Pathname where the private library files will reside? (~name ok)
[/perl/lib/5.32.1]
Where do you want to put the public architecture-dependent libraries? (~name ok)
[/perl/lib/5.32.1/x86_64-linux]
Pathname for the site-specific library files? (~name ok)
[/perl/lib/site_perl/5.32.1]
Pathname for the site-specific architecture-dependent library files? (~name ok)
[/perl/lib/site_perl/5.32.1/x86_64-linux]

然后执行make命令。后来由于其他错误使测试失败。

然后没有运行 make distclean 命令，我重新运行配置
-Dinstallprefix 选项

./Configure -Dinstallprefix=/test/user/home/perl -des

按如下方式填充@INC

/test/user/home/perl/lib/5.32.1 /test/user/home/perl/lib/site_perl/5.32.1 /test/user/home/perl/lib/5.32.1/x86_64-linux
/perl/lib/site_perl/5.32.1/x86_64-linux /perl/lib/site_perl/5.32.1 /perl/lib/5.32.1/x86_64-linux /perl/lib/5.32.1

要解决此问题，请执行以下步骤，

make distclean  

./Configure -des -Dprefix=/test/user/home/perl -Dusethreads

现在 @INC 已正确填充

@INC:
    /test/user/home/perl/lib/site_perl/5.32.1/x86_64-linux-thread-multi
    /test/user/home/perl/lib/site_perl/5.32.1
    /test/user/home/perl/lib/5.32.1/x86_64-linux-thread-multi
    /test/user/home/perl/lib/5.32.1

现在 DBI 安装运行成功。
