perl - 无法在 conda 环境中通过 cpanm 安装 perl 模块

Question

我正在尝试在安装了 perl 的 conda 环境中通过 cpanm 安装 perl 模块。conda 环境是使用以下定义构建的:

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

安装了以下包的环境结果:

conda env 被激活:

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

然后从 shell 中:

安装不同的 perl 包 (DBI) 时也会发生同样的情况。我真的无法克服这个错误，所以我强烈寻求帮助，谢谢你的建议。

是的，你是对的!在 activate conda perl_env 中我有奇怪的行为。如果我输入:

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

老实说，众所周知，在我的系统中 which 命令的行为很奇怪。我不希望这是问题的原因...

PS: conda env 4520f5b9 与 perl_env 相同

Answer 1

我可以尝试回答问题的第一部分:How to use the correct perl when installing packages in the conda environment。我在 Ubuntu 20.04 上:

• 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

• 在环境中安装了 perl 5.26.2:

$ conda install -c anaconda perl

• 初始化cpan(假设我之前没有任何cpan配置(~/.cpan/)和本地库(~/perl5/) 在我的主目录中设置)。选择下面的 local::lib 选项:

$ 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.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Would you like to configure as much as possible 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.  CPAN can help you by bootstrapping the local::lib
module or by configuring itself to use 'sudo' (if available).  You may also
resolve this problem manually if you need to customize your setup.

What approach do you want?  (Choose 'local::lib', 'sudo' or 'manual')
 [local::lib]           


Autoconfiguration complete.

local::lib is installed. You must now add the following environment variables
to your shell configuration files (or registry, if you are on Windows) and
then restart your command line shell and CPAN before installing modules:

PATH="/home/hakon/perl5/bin${PATH:+:${PATH}}"; export PATH;
PERL5LIB="/home/hakon/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}"; export PERL5LIB;
PERL_LOCAL_LIB_ROOT="/home/hakon/perl5${PERL_LOCAL_LIB_ROOT:+:${PERL_LOCAL_LIB_ROOT}}"; export PERL_LOCAL_LIB_ROOT;
PERL_MB_OPT="--install_base \"/home/hakon/perl5\""; export PERL_MB_OPT;
PERL_MM_OPT="INSTALL_BASE=/home/hakon/perl5"; export PERL_MM_OPT;

Would you like me to append that to /home/hakon/.bashrc now? [yes] no

请注意，我对上一个问题的回答是“否”。

PERL5LIB="/home/hakon/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}"; export PERL5LIB;
PERL_LOCAL_LIB_ROOT="/home/hakon/perl5${PERL_LOCAL_LIB_ROOT:+:${PERL_LOCAL_LIB_ROOT}}"; export PERL_LOCAL_LIB_ROOT;
PERL_MB_OPT="--install_base \"/home/hakon/perl5\""; export PERL_MB_OPT;
PERL_MM_OPT="INSTALL_BASE=/home/hakon/perl5"; export PERL_MM_OPT;

• 现在我将生成的本地lib复制到conda环境中:

$ echo $CONDA_PREFIX
/home/hakon/anaconda3/envs/perl_test
$ mv ~/perl5 /home/hakon/anaconda3/envs/perl_test

• 然后配置conda环境，使环境激活时本地lib也被激活:

$ mkdir -p $CONDA_PREFIX/etc/conda/activate.d
$ vim $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh

• 在之前的env_vars.sh文件中添加以下内容:

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"

• 重启conda环境加载以上环境变量:

$ conda deactivate
$ conda activate perl_test

• 安装cpanm

$ cpan App::cpanminus

• 安装模块:

$ which cpanm

所以这失败了。如果我尝试手动安装失败的模块 Acme::Damn:

$ wget https://cpan.metacpan.org/authors/id/I/IB/IBB/Acme-Damn-0.08.tar.gz
$ tar zxvf Acme-Damn-0.08.tar.gz
$ cd Acme-Damn-0.08
$ perl Makefile.PL

make: *** [Makefile:337: Damn.o] Error 127

它表明 make 试图使用一个不存在的 C 编译器:

 /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:

$ 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，它使用与用于编译 perl 的相同的 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)了一个预编译的 perl(所以 cc 变量指的是另一台机器上的编译器，即用于编译的机器perl 与)

可能这意味着您不能(不应该)使用下载的预编译 perl 安装 XS 模块。我建议您改为在同一台机器上从源代码构建 perl。

编辑

糟糕的是，实际上可以通过运行来安装用于构建 perl 的相同编译器:

$ 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

但我仍然无法让 perl Makefile.PL 使用那个版本..

在 follow-up question 应用补丁后，我能够安装模块:
