如何在 conda 中静音或抑制 gfortran （或 clang？）后端？

2024-05-08

我一直致力于构建一个非常特殊的 conda 环境，专为python and R与串扰使用rpy2。我想出的方法可以安装正确的R包如下：

# install_main_environment.sh
now=$(date +"%T")
echo "Start Time: $now"

## Create Main Environment (OSX-64)
conda create -n python3 python=3 --yes
source activate python3

## Jupyter
conda install jupyterlab --yes

## R
conda install -c r r --yes
conda install -c r r-essentials --yes
conda install -c r rstudio --yes
conda install gfortran_osx-64 --yes
conda install -c anaconda clangxx_osx-64 --yes
conda install rpy2 --yes

## Install Python Packages
source ./install_python_packages.sh

## Install R Packages
RScript ./install_r_packages.r

# End
now=$(date +"%T")
echo "End Time: $now"

然而，其中一行使后端变得极其冗长，因此每次我获取/停用环境或安装软件包时，我都会得到一个非常冗长的后端。

我怎样才能抑制这个或永久静音额外的文本？在我的 bash 配置文件中，当我激活环境时，我将 stderr 和 stdout 定向到 /dev/nullsource activate python3 > /dev/null 2>&1但这只是一个补丁，并不通用。

我的两台工作电脑都存在这种情况：OSX 10.11.6 (El Capitan)和我的个人电脑OSX Sierra.

这是我在下面提到的输出的示例：

以下是链接`pastebin`对于请求的输出/脚本：

正如 Tarun Lalwani 在评论中所建议的：

如果您查看以下文件夹

/Users/jespinoz/anaconda/envs/python3/etc/conda

有一个activate.d and deactivate.d同一文件夹内，在期间执行activate and deactivate

这些文件有以下代码部分

if [ $? -ne 0 ]; then
  echo "ERROR: $(_get_sourced_filename) failed, see above for details"
else
  if [ -f /tmp/new-env-$$.txt ]; then
    rm -f /tmp/new-env-$$.txt || true
  fi
  env > /tmp/new-env-$$.txt

  echo "INFO: $(_get_sourced_filename) made the following environmental changes:"
  diff -U 0 -rN /tmp/old-env-$$.txt /tmp/new-env-$$.txt | tail -n +4 | grep "^-.*\|^+.*" | grep -v "CONDA_BACKUP_" | sort
fi
rm -f /tmp/old-env-$$.txt /tmp/new-env-$$.txt || true

您需要注释这些以禁用详细输出。这段代码基本上保存了当前env到文件然后运行激活码，捕获env再次并打印差异
