如何在conda中沉默或抑制gfortran(或clang?)后端? [英] How to silence or suppress gfortran (or clang?) backend in conda?
问题描述
我一直在努力构建一个针对python和R设计的非常特殊的conda环境，并使用rpy2进行串扰.我想到的可以安装正确的R软件包的方法如下:
I have been working on building a very particular conda environment designed for python and R with cross-talk using rpy2. The recipe I came up with that works to install the proper R packages is the following:
# 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"
但是，这些行之一使后端变得非常冗长，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.
However, one of these lines has made the backend extremely verbose so everytime I source/deactivate an environment or install a package I get a very verbose backend.
如何抑制这种情况或永久使多余的文本静音?在激活环境时，在bash个人资料中，我指示stderr& stdout到/dev/null source activate python3 > /dev/null 2>&1，但这只是一个不通用的补丁.
How can I suppress this or silence the extra text permanently? In my bash profile when I activate my environment, I direct the stderr & stdout to /dev/null source activate python3 > /dev/null 2>&1 but this is only a patch that is not universal.
我的两台工作计算机都存在这种情况:
OSX 10.11.6 (El Capitan)和我的个人计算机OSX Sierra.
This situation exists for both my work computer:
OSX 10.11.6 (El Capitan) and my personal computer OSX Sierra.
这是我在下面引用的输出示例:

推荐答案
如果您查看以下文件夹
/Users/jespinoz/anaconda/envs/python3/etc/conda
同一文件夹中有一个activate.d和deactivate.d文件夹，该文件夹在activate和deactivate
There is a activate.d and deactivate.d folder inside the same, which gets executed, during activate and deactivate
这些文件具有以下代码部分
These files have below code section
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
您需要对它们进行注释以禁用详细输出.该代码基本上将当前的env保存到文件中，然后运行激活代码，再次捕获env并打印差异
You need to comment these to disable the verbose output. This code basically saves current env to a file and then run the activation code, capture env again and print the diff
