Question

我有一些旧的Perl代码，我正在尝试使用我构建的Perl 5.14.1版本。但由于某种原因，我没有Perl模块NDBM_File。

$ perl -MNDBM_File -e1;
Can't locate NDBM_File.pm in @INC (@INC contains: /apps/perl-5.14.1/lib/dev_perl/x86_64-linux-thread-multi /apps/perl-5.14.1/lib/dev_perl /apps/perl-5.14.1/lib/vendor_perl/5.14.1/x86_64-linux-thread-multi /apps/perl-5.14.1/lib/vendor_perl/5.14.1 /apps/perl-5.14.1/lib/5.14.1/x86_64-linux-thread-multi /apps/perl-5.14.1/lib/5.14.1 /apps/perl-5.14.1/lib/site_perl .).
BEGIN failed--compilation aborted.

这是我得到的perl -V输出......

我确实有这个档案......

/apps/perl-5.14.1/lib/5.14.1/Memoize/NDBM_File.pm

...但是“使用NDBM_File”失败了。

我是否构建了错误的Perl？

来自https://metacpan.org/module/AnyDBM_File：

                        odbm    ndbm    sdbm    gdbm    bsd-db
                        ----    ----    ----    ----    ------
Linkage comes w/ perl   yes     yes     yes     yes     yes
Src comes w/ perl       no      no      yes     no      no
...

这意味着唯一支持“开箱即用”的DBM后端是SDBM_File。我想你必须安装libgdbm-dev包并重新编译你的Perl。

我的Perl 5.14缺少NDBM_File
