!How-To-Install-Perl.jpeg Perl 是一种功能丰富的计算机程序语言,运行在超过 100 种计算机平台上,适用广泛,从大型机到便携设备,从快速原型创建到大规模可扩展开发。在生物信息分析领域,Perl 主要是做数据预处理、文本处理和格式转换、对算法效率要求不高的分析软件开发,系统管理和 pipeline 搭建等工作。这里对 Linux(主要是 CentOS)、windows 下 Perl 的安装做一个备忘。

一、CentOS 7 下安装 Perl

1. 源码包下载

在官方网站下载新版本的源码包:http://www.perl.org/get.html,我下载的是 perl-5.26.1.tar.gz

2. 解压,设置源码

$ tar zvxf perl-5.26.1.tar.gz
$ cd perl-5.26.1
$ ./Configure --help
Usage: Configure [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
                 [-U symbol] [-U symbol=] [-A command:symbol...]
  -d : use defaults for all answers.
  -e : go on without questioning past the production of config.sh.
  -f : specify an alternate default configuration file.
  -h : print this help message and exit (with an error status).
  -r : reuse C symbols value if possible (skips costly nm extraction).
  -s : silent mode, only echoes questions and essential information.
  -D : define symbol to have some value:
         -D symbol         symbol gets the value 'define'
         -D symbol=value   symbol gets the value 'value'
       common used examples (see INSTALL for more info):
         -Duse64bitint            use 64bit integers
         -Duse64bitall            use 64bit integers and pointers
         -Dusethreads             use thread support
         -Dinc_version_list=none  do not include older perl trees in @INC
         -DEBUGGING=none          DEBUGGING options
         -Dcc=gcc                 choose your compiler
         -Dprefix=/opt/perl5      choose your destination
  -E : stop at the end of questions, after having produced config.sh.
  -K : do not use unless you know what you are doing.
  -O : ignored for backward compatibility
  -S : perform variable substitutions on all .SH files (can mix with -f)
  -U : undefine symbol:
         -U symbol    symbol gets the value 'undef'
         -U symbol=   symbol gets completely empty
       e.g.:  -Uversiononly
  -A : manipulate symbol after the platform specific hints have been applied:
         -A append:symbol=value   append value to symbol
         -A symbol=value          like append:, but with a separating space
         -A define:symbol=value   define symbol to have value
         -A clear:symbol          define symbol to be ''
         -A define:symbol         define symbol to be 'define'
         -A eval:symbol=value     define symbol to be eval of value
         -A prepend:symbol=value  prepend value to symbol
         -A undef:symbol          define symbol to be 'undef'
         -A undef:symbol=         define symbol to be ''
       e.g.:  -A prepend:libswanted='cl pthread '
              -A ccflags=-DSOME_MACRO
  -V : print version number and exit (with a zero status).

# 设置源码
$ ./Configure -des -Dprefix=/usr/local/software/Perl-5.26 -Dusethreads -Uversiononly

3. 编译安装

$ make
......
make[1]: *** [IO.o] Error 1
make[1]: Leaving directory `/users/rmi1/build/perl-5.12.0/dist/IO'
Unsuccessful make(dist/IO): code=512 at make_ext.pl line 449.
make: *** [lib/auto/IO/IO.so] Error 2

如果在 make 编译过程中出现如上报错,请参考 Make error when compiling Perl 5.12.1 (RHEL 5.5) 执行下面操作:

$ make clean
$ unset C_INCLUDE_PATH
$ ./Configure -des -Dprefix=/usr/local/software/Perl-5.26 -Dusethreads -Uversiononly
$ make

继续验证编译,执行安装:

$ make test
$ make install   # 命令完成后,基本安装就完成了

4. 调整环境变量

在 \~/.bashrc 中把 perl 添加到 PATH 中,然后 source \~/.bashrc 刷新。

export PATH="/usr/local/software/Perl-5.26/bin:$PATH"

5. 安装完成

$ perl -version

$ perl -V    # 该命令会把对应 perl 配置、模块路径所有信息汇总打印出来

二、Windows 7 下安装 Perl

windows 下的 Perl 安装推荐使用 ActivePerl(https://www.activestate.com/products/activeperl/),安装步骤如下。

2.1 安装包下载

在这里我们下载 64-bit 的 Perl-5.26.3

2.2 安装与设置

ActivePerl-5.26.3.2603-MSWin32-x64-a95bce075.exe 安装包下载完后,我们直接点击进行安装。 image.png

选择 “Custom” 自定义安装: image.png

自定义安装路径: image.png

把 Perl 添加到系统环境变量: image.png

Perl 安装完成后,我们在 DOC 命令行输入 perl -V,可以看到详细的相关信息: image.png

如果我们在安装过程中没有勾选把 Perl 添加到系统环境变量,DOC 中直接执行 perl -V 会出现 “‘perl’ is not recognized as an internal or external command” 提示,这时候我们需要手动把 perl 添加到 Windows 的系统环境变量中就可以了。 image.png

2.3 配置 cpan

为了更好对 Perl 进行扩展,方便以后的模块安装,我们最好配置一下 cpan。ActivePerl 有个好处就是在初始化 cpan 的时候会自动把 dmake、gcc、g++、mingw32-make 等 windows 常用的编译工具一起安装到 “$Dprefix/site/bin” 目录下,免去了我们手动安装这些编译器的各种麻烦。 image.png

2.4 安装完成

到这里,windows 下的 ActivePerl(perl-5.26)就安装完成了!
