conda learning post

This is a conda learning post that records my process from contacting conda to solving various problems.

1. Install after downloading anaconda

1. cd to the path
2. Grant permissions:
   chmod u+x Anaconda.sh
3. ./Anaconda.sh
4. Create environment:
   conda create -n XXX
5. Activate to enter:
   conda activate XXX

2.报错：Solving environment: failed with initial frozen solve. Retrying with flexible solve.

#Try to modify flexiblility

conda config --add channels conda-forge
conda config --set channel_priority flexible

#In fact, regardless of the error, the installation may be successful

3. Created a python2 mother environment, which can be used unlimitedly in the future

conda create -n py2

#复制到新环境
conda create -n newenv --clone py2

#如果需要可以删除旧环境
conda remove -n oldenv --all

4. Install the software package

#一般来说
conda install pgname 
#或者
conda install -c bioconda pgname

#如果安装过程过于缓慢，可以先找到包的路径
#参考：[Anaconda找包](https://blog.csdn.net/Erice_s/article/details/80156191)
#以biopython为例
anaconda search -t conda biopython
anaconda show anaconda/biopython
conda install --channel https://conda.anaconda.org/anaconda biopython

ADD. If you want to download offline

nohup conda install -y software &

ADD. Download the installation package in the mirror and install offline

#将下载好的安装包拷贝到~/Anaconda3/pkgs/
conda install --use-local software.gz
