如何在 conda 中静音或抑制 gfortran（或 clang？）后端？
How to silence or suppress gfortran (or clang?) backend in conda?
我一直致力于构建一个非常特殊的 conda 环境，专为 python 和 R 设计，使用 rpy2 进行串扰。我提出的安装正确 R 软件包的方法如下：
# 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非常冗长，所以每次我 source/deactivate 一个环境或安装一个包时，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，当我激活我的环境时，我将 stderr & stdout 指向 /dev/null source activate python3 > /dev/null 2>&1但这只是一个不通用的补丁。
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。

脚本
如果您查看以下文件夹
/Users/jespinoz/anaconda/envs/python3/etc/conda
里面有一个 activate.d 和 deactivate.d 文件夹，在 activate 和 deactivate
期间执行
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

echo "INFO: $(_get_sourced_filename) made the following environmental changes:"

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。这段代码基本上将当前 env 保存到一个文件，然后 运行 激活码，再次捕获 env 并打印 diff
