无法在conda环境中通过cpanm安装Perl模块

本文介绍了无法在conda环境中通过cpanm安装Perl模块的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图在安装了perl的conda环境中通过cpanm安装perl模块.conda环境的构建具有以下定义:

I'm trying to install perl modules via cpanm inside conda environment with perl installed. The conda environment was build with following definition:

name: perl_env channels: - bioconda - conda-forge - defaults dependencies: - perl=5.26 - perl-app-cpanminus - perl-local-lib - gcc_impl_linux-64 - gxx_linux-64 - openmpi=4.1.0

环境结果中安装了以下软件包:

The environment results with the following packages installed:

conda env被激活:

The conda env was activated with:

source /igatech/rd/dev/miniconda3/bin/activate conda activate perl_env

然后从外壳:

eval $(perl -I/igatech/rd/dev/snakemake-workflows/annotation-maker_p/local/perl5/lib/perl5 -Mlocal::lib=/igatech/rd/dev/snakemake-workflows/annotation-maker_p/local/perl5)

然后尝试使用cpanm安装forks软件包:

Then try install forks packages with cpanm:

详细了解该错误:

在安装不同的perl软件包(DBI)时也会发生同样的情况.我真的无法克服此错误，因此我强烈要求帮助，谢谢你的建议.

The same happens while installing different perl packages (DBI). I am not really able to overcome this error so I strongly ask for help, thank you in advice.

是的，您是对的！在激活conda perl_env 中，我得到了奇怪的行为.如果我输入:

Yes, you are right! Within the activate conda perl_env I got strange behaviours. If I type:

which perl /usr/bin/perl

如果我输入:

command -v perl /igatech/rd/dev/snakemake-workflows/annotation-maker_p/tests/snakemake/.snakemake/conda/4520f5b9/bin/perl

或

whereis perl perl: /usr/bin/perl /igatech/rd/dev/snakemake-workflows/annotation-maker_p/tests/snakemake/.snakemake/conda/4520f5b9/bin/perl /usr/share/man/man1/perl.1.gz

如果我这样做:

perl --version This is perl 5, version 26, subversion 2 (v5.26.2) built for x86_64-linux-thread-multi Copyright 1987-2018, Larry Wall ...

或者如果我这样做:

/usr/bin/perl --version This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi (with 40 registered patches, see perl -V for more detail) Copyright 1987-2012, Larry Wall ...

说实话，众所周知，在我的系统中，哪个命令的行为异常.我不希望这是问题的原因...

To be honest it's known that in my system which command behaves strangely. I wouldn't like that this was the cause of the problem...

PS:conda env 4520f5b9 与 perl_env

PS: conda env 4520f5b9 is same as perl_env

推荐答案

我可以尝试回答问题的第一部分:在conda环境中安装软件包时如何使用正确的perl.我使用的是Ubuntu 20.04:

I can try answer the first part of the question: How to use the correct perl when installing packages in the conda environment. I am on Ubuntu 20.04:

• 首先我将Anaconda安装到/home/hakon/anaconda3
• 然后我创建了一个测试环境:

$ conda create --name perl_test $ conda activate perl_test

• 将perl 5.26.2安装到环境中:
$ conda install -c anaconda perl
• 初始化的 cpan (假设我以前没有任何 cpan 配置(〜/.cpan/)和本地lib(〜/perl5/)设置在我的主目录中).选择下面的 local :: lib 选项:
• Initialized cpan (this assumes that I did not have any previous cpan configuration (~/.cpan/) and local lib (~/perl5/) set up in my home directory). Choose the local::lib option below:
$ cpan Loading internal null logger. Install Log::Log4perl for logging messages Sorry, we have to rerun the configuration dialog for CPAN.pm due to some missing parameters. Configuration will be written to <</home/hakon/.cpan/CPAN/MyConfig.pm>> CPAN.pm requires configuration, but most of it can be done automatically.

[yes] <install_help> Warning: You do not have write permission for Perl library directories. To install modules, you need to configure a local Perl library directory or escalate your privileges.

请注意，我回答否".关于上一个问题.

• 现在，我将生成的本地库复制到conda环境:
$ echo $CONDA_PREFIX /home/hakon/anaconda3/envs/perl_test $ mv ~/perl5 /home/hakon/anaconda3/envs/perl_test
• 然后配置conda环境，以便在激活环境时激活本地库:
$ mkdir -p $CONDA_PREFIX/etc/conda/activate.d $ vim $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh
• 将以下内容添加到以前的 env_vars.sh 文件中:
export PATH="$CONDA_PREFIX/perl5/bin${PATH:+:${PATH}}" export PERL5LIB="$CONDA_PREFIX/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}"; export PERL_LOCAL_LIB_ROOT="$CONDA_PREFIX/perl5${PERL_LOCAL_LIB_ROOT:+:${PERL_LOCAL_LIB_ROOT}}"; export PERL_MB_OPT="--install_base \"$CONDA_PREFIX/perl5\"" export PERL_MM_OPT="INSTALL_BASE=$CONDA_PREFIX/perl5"
• 重新启动conda环境以加载上述环境变量:
$ conda deactivate $ conda activate perl_test
• 安装 cpanm
$ cpan App::cpanminus
• 安装模块:

所以这失败了.如果我尝试手动安装发生故障的模块 Acme :: Damn :

So this fails. If I try to install the failing module Acme::Damn manually:

它表明 make 试图使用不存在的C编译器:

It shows that make tries to use a nonexistent C compiler:

/tmp/build/80754af9/perl_1527832170752/_build_env/bin/x86_64-conda_cos6-linux-gnu-gcc

cc 的perl配置数据给出了为什么会发生这种情况的线索:

A clue to why this happens is given by the perl configuration data for cc:

$ perl -V | grep cc=./ cc='/tmp/build/80754af9/perl_1527832170752/_build_env/bin/x86_64-conda_cos6-linux-gnu-gcc'

我认为，当perl尝试编译XS模块时，它使用的是与用于编译 perl 的C编译器相同的C编译器.但是在这种情况下，编译器不再存在，因为conda安装(下载)了预编译的perl(因此， cc 变量引用另一台计算机上的编译器，该计算机用于编译该计算机). perl 与)

I think that when perl tries to compile an XS module it uses the same C compiler that was used to compile perl with. But in this case that compiler does not exist any more, since conda installed (downloaded) a pre-compiled perl (so the cc variable refers to a compiler on another machine, the machine that was used to compile perl with)

这可能意味着您不能(不应)使用下载的预编译的perl安装XS模块.我建议您改为在同一台计算机上从源代码构建perl.

Probably this means that you cannot (should not) install XS modules with a downloaded precompiled perl. I would recommend that you build perl from source on the same machine instead.

修改

糟糕，实际上可以通过运行以下命令安装用于构建perl的相同编译器:

My bad, it is actually possible to install the same compiler that was used to build perl by running:

$ conda install -c anaconda gcc_linux-64 $ which x86_64-conda_cos6-linux-gnu-gcc /home/hakon/anaconda3/envs/perl_test/bin/x86_64-conda_cos6-linux-gnu-gcc

但是我仍然无法使 perl Makefile.PL 使用该版本..

But still I am not able to make perl Makefile.PL use that version yet..
