conda的安装和使用

安装conda

安装miniconda in macos的文档： Installing conda — conda 24.1.3.dev33 documentation

静默安装

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-x86_64.sh -O ~/miniconda.sh
bash ~/miniconda.sh -b -p $HOME/miniconda

参数解释： To run the silent installation of Miniconda for macOS or Linux, specify the -b and -p arguments of the bash installer. The following arguments are supported:

-b: Batch mode with no PATH modifications to shell scripts. Assumes that you agree to the license agreement. Does not edit shell scripts such as .bashrc, .bash_profile, .zshrc, etc.
-p: Installation prefix/path.
-f: Force installation even if prefix -p already exists.

注意：安装完成后需要初始化，这样每次shell进入会默认进入到base环境

source miniconda/bin/activate
conda init --all

In order to initialize after the installation process is done, first run source<path to conda>/bin/activate and then run conda init --all.

其他命令

升级：conda update conda 卸载：rm -rf ~/miniconda
