Getting Error on Text/CSV.pm when running Perl Script
提问by NerdyBird
When running a Perl Script that grabs content from an Oracle DB and exports the results into a CSV, I am getting this error when trying to run it via the command line:
当运行从 Oracle DB 获取内容并将结果导出到 CSV 的 Perl 脚本时，我在尝试通过命令行运行它时收到此错误：
Can't locate Text/CSV.pm in @INC (@INC contains:

./OracleScript.pl line 4. BEGIN failed--compilation aborted at
./OracleScript.pl line 4.
I interpret this to mean that the Module is not installed. So, I tried to install it with the following command:
我将此解释为未安装模块。因此，我尝试使用以下命令安装它：
/usr/bin/perl -MCPAN -e'install Text::CSV_pm'
I get this error:
我收到此错误：

Cannot install Text::CSV_pm, don't know what it is. Try the command
i /Text::CSV_pm/
to find objects with matching identifiers.
Can anybody shed some light on my issues, and how to remedy this?
任何人都可以对我的问题有所了解，以及如何解决这个问题？

Given that you're using the system Perl (and, from a comment, it seems you have root) then the easiest approach is probably to install the package that is pre-built for your Linux distribution.
鉴于您使用的是系统 Perl（并且，从评论来看，您似乎拥有 root 用户），那么最简单的方法可能是安装为您的 Linux 发行版预先构建的软件包。
For a Debian/Ubuntu-based system:
对于基于 Debian/Ubuntu 的系统：
$ sudo apt-get install libtext-csv-perl
For a RedHat/Centos/Fedora-based system:
对于基于 RedHat/Centos/Fedora 的系统：
$ sudo yum install perl-Text-CSV

If you are installing a module with CPAN, the syntax is
如果您使用 CPAN 安装模块，则语法为
perl -MCPAN -e'install Module::Name'
No extension needed
无需扩展
So you need
所以你需要
perl -MCPAN -e'install Text::CSV'
Otherwise CPAN will search for a module called Text::CSV_pm, which (obviously) doesn't exist.
否则 CPAN 将搜索名为 Text::CSV_pm 的模块，该模块（显然）不存在。
You can also use cpan in interactive module, which is a little more friendly:
也可以在交互模块中使用cpan，友好一点：
perl -MCPAN -e shell
It's best to run it as root (i.e. sudo perl -MCPAN -e shell) if you're trying to update your system perl, or set up cpan so that it writes to directories that you own (e.g. your home directory).
sudo perl -MCPAN -e shell如果您尝试更新系统 perl 或设置 cpan 以便它写入您拥有的目录（例如您的主目录），最好以 root 身份运行它（即）。
