安装ora2pg遇到如下问题

通过源码安装ora2pg成功后，查询帮助信息报错

[root@localhost bin]# ora2pg --help Can't locate open.pm in @INC (you may need to install the open module) (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /usr/local/share/perl5/Ora2Pg.pm line 1931. BEGIN failed--compilation aborted at /usr/local/share/perl5/Ora2Pg.pm line 1931. Compilation failed in require at /usr/local/bin/ora2pg line 27. BEGIN failed--compilation aborted at /usr/local/bin/ora2pg line 27.

重新安装perl，发现安装的是同样的版本，但是问题解决了，奇怪

 [root@localhost bin]# yum install perl

依赖的库版本如下：

[root@localhost ora2og]# perl check.pl CPAN         -- 2.36 DBD::Oracle  -- 1.83 DBD::Pg      -- 3.17.0 DBI          -- 1.643 ExtUtils::Config -- 0.008 ExtUtils::Helpers -- 0.026 ExtUtils::InstallPaths -- 0.012 IO::Tty      -- 1.17 IPC::Run     -- 20231003.0 JSON         -- 4.10 Module::Build::Tiny -- 0.047 Module::Signature -- 0.88 Ora2Pg       -- 21.1 Perl         -- 5.26.3 Readonly     -- 2.05 Test::Simple -- 1.302195
