perl DBI 模块安装错误

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

下载了 DBI-1.643 存档，在提取执行 Makefile.PL 失败后

perl Makefile.PL

Warning: PERL_LIB (/perl/lib/5.32.1) seems not to be a perl library directory

发现不存在的路径是从 @INC 引用的

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 到哪里吗获取这些不存在的路径

/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

是否有任何方法可以限制 @INC 附加不存在的路径？

Answer 1

我认为您只需要 -Dprefix=/...。还有其他事情也需要放在正确的地方。不过，您不需要设置 PERL5LIB，因为 perl 应该使用您的前缀作为其默认 @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。这就是你想做的吗？

至于其他目录， INSTALL 文档描述了显示的各种目录在@INC 中。

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。

上次在 perl 安装过程中，我至少运行了一次以下命令

./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]

，然后执行了 make 命令。后来由于其他错误， make 测试失败。

然后，在不运行 make distclean 命令的情况下，我重新运行了配置
-Dinstallprefix 选项

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

按如下所示填充@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

要修复此问题，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 安装已成功运行。
