在安装conda软件包的过程中更新@INC变量

标签: perl environment-variables conda environment conda-build

我正在尝试安装Perl模块的conda软件包。到目前为止,我已经可以使用conda-build创建包。为此,我有一个包含build.shmeta.yaml文件的食谱。

然后我在新环境中使用conda-install安装它,我希望能够运行刚安装的Perl模块中的一些Perl脚本。

所有这些步骤都可以正常工作,但是当我运行某些脚本时,我会出错:

Can't locate PMP/util.pm in @INC (you may need to install the PMP::util module) (@INC contains: /.autofs/home/antoine/anaconda2/envs/testCustomChannel/lib/site_perl/5.26.2/x86_64-linux-thread-multi /.autofs/home/antoine/anaconda2/envs/testCustomChannel/lib/site_perl/5.26.2 /.autofs/home/antoine/anaconda2/envs/testCustomChannel/lib/5.26.2/x86_64-linux-thread-multi /.autofs/home/antoine/anaconda2/envs/testCustomChannel/lib/5.26.2 .)

如您所见,执行Perl时似乎无法识别我的Perl模块的某些模块。我知道,要解决此问题,我可以修改@INC变量,并将bin /添加到PATH,并将lib /添加到PERL5LIB,但是我需要在模块安装期间自动执行此过程。

我真的不知道应该在哪里修改环境变量。例如,在创建包期间通过在build.sh中添加一些内容?还是应该在安装过程中进行管理?如果可以,该怎么办?

任何建议将不胜感激

谢谢

另一种可以帮助你们更好地了解我的情况的编辑。我刚刚意识到,在构建软件包时,我拥有PMP::util的perl模块的lib文件夹位于lib/site_perl/5.26.0/Perl_Module下。我非常确定,如果我能够直接将其安装在lib/文件夹下,它将解决此问题。但是我不确定如何修改build.sh文件来修改我们构建perl模块的位置。

这是一个简单的示例,说明如何创建一个conda软件包来安装Perl模块(取决于CPAN模块),该软件包可能会帮助您解决问题:

在Linux上安装miniconda

$ wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
$ bash Miniconda3-latest-Linux-x86_64.sh
# NOTE: I answered "yes" on the question:
#   "Do you wish the installer to initialize Miniconda3 ?" in the
#   previous command. This will modify ~/.bashrc
$ source ~/.bashrc # activates base environment
# Next command: Do not automatically activate conda for every terminal window,
# instead run "conda activate" from a given terminal window to
# activate locally. The following command also creates ~/.condarc
$ conda config --set auto_activate_base False

创建程序包:

perl-hello / meta.yaml

package:
  name: perl-hello3
  version: "1.0"

source:
  path: ../src # NOTE: if you had put "src" in same folder as "meta.yaml", 
               # conda-build would have include the src folder in info/recipe in 
               # the generated package. It is not necessary to include  the 
               # source code in the generated package.

requirements:
  build:
    - perl >= 5.22
    - make

  run:
    - perl >= 5.22

use Data::Dump;
sub hello {
    print "Hello world!\n";
    my $str = "Testing Perl module Data::Dump";
    dd $str;
}

build.sh

# PERL_MM_USE_DEFAULT=1  -> automatically answer "yes" on config questions
PERL_MM_USE_DEFAULT=1 cpan App::cpanminus
perl ${PREFIX}/bin/cpanm Data::Dump
perl Makefile.PL INSTALLDIRS=site
make
make install

请注意,我使用cpanm运行了perl ${PREFIX}/bin/cpanm。我无法简单地以cpanm的身份运行它,有关更多信息,请参见Can you rely on the shebang of an installed command during build?

构建程序包

$ conda-build .

(记下生成的输出,并确定生成的包的路径。在我的情况下,路径名称为:

/home/hakon/miniconda3/conda-bld/linux-64/perl-hello3-1.0-pl526_0.tar.bz2

将程序包上传到anaconda服务器

  • Anaconda Cloud

  • 注册新用户
  • 安装客户端

    $ conda install anaconda-client
    
  • 登录到您的帐户:

    $ anaconda login
    
  • 上传生成的包:

    $ anaconda upload /home/hakon/miniconda3/conda-bld/linux-64/perl-hello3-1.0-pl526_0.tar.bz2
    

测试软件包(可以在任何Linux机器上完成):

  • 创建一个新环境:

     $ conda create --name perltest
     $ conda activate perltest
    
  • 在新环境中安装软件包:

     $ conda install -c hakonhagland perl-hello3 
     # Alternatively: You can test the package locally before uploading with
     #   "conda install --use-local perl-hello3"
    
  • 测试程序包:

     $ perl -E 'use My::Module; hello'
     Hello world!
     "Testing Perl module Data::Dump"
