一、簡介
Anaconda是一個發行包，里面集成打包了很多的軟件包，使用conda包管理器來安裝軟件，比較方便，但是Anaconda軟件包太大，個人不太喜歡，想自己定制。Miniconda中只有Conda包管理器，正是我想要的，下面簡單介紹一下Miniconda的簡單配置方法。
二、配置使用
1. 下載軟件包：
2. 安裝：
bash Miniconda3-4.3.14-Linux-x86_64.sh

####安裝完成######
3. 查看並使得conda命令生效（windows不用）
（1）查看：
tail -3 ~/.bashrc
若顯示如下，則表示命令已經添加到用戶環境變量中：
# added by Miniconda3 4.3.14 installer
export PATH="/home/gql/miniconda3/bin:$PATH"
（2）使生效
source ~/.bashrc # .bashrc文件生效
4. 更換conda源和pip源：
（1）conda源：（使用清華開源鏡像站的源）
編寫配置文件：
vim ~/.condarc # 新建配置文件並打開
若windows：
C:\Users\用戶名\.condarc
channels: - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ - defaults show_channel_urls: true
英文輸入法條件下，按i進入輸入模式，把上述配置拷貝進去即可。
輸入完之后，按esc鍵，然后按 :x 保存並退出。
（2）pip源：（使用清華開源鏡像站的源）
mkdir ~/.pip # 在用戶家目錄下創建.pip 隱藏文件夾
vim ~/.pip/pip.conf # 新建配置文件並打開
若windows：
C:\Users\用戶名\pip\pip.ini
[global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple
或豆瓣源：
[global] trusted-host = pypi.douban.com index-url = http://pypi.douban.com/simple
5. 創建python任意版本虛擬環境：
比如：python2.7
conda create --name py2 python=2.7
查看當前conda管理的虛擬環境有哪些：
conda info --envs
6. 修改進入虛擬環境的命令（windows不用）
vim ~/.bashrc # 在文件的最下面添加下面兩行，不是必須（個人喜好 ^_^）
alias workon='source activate'
alias pybye='source deactivate'
修改環境變量之后使生效：
source ~/.bashrc
此時進入虛擬環境的命令：
workon py2
離開虛擬環境的命令：
pybye
7. 進入虛擬環境安裝軟件包：
workon py2 # 進入虛擬環境，或 source activate py2 / windows：activate py2
pip install 軟件包名 # 安裝軟件包
附加常用命令：
pip list # 查看當前虛擬環境存在的軟件包
pip freeze # 查看當前虛擬環境存在的軟件包，同時顯示處具體版本
比如在某個相同環境軟件包重定向到文件：pip freeze > py2.txt
再使用相同環境的文件安裝軟件包：pip install -r py2.txt
pip的所有命令：
Usage: pip <command> [options] Commands: install Install packages. download Download packages. uninstall Uninstall packages. freeze Output installed packages in requirements format. list List installed packages. show Show information about installed packages. check Verify installed packages have compatible dependencies. config Manage local and global configuration. search Search PyPI for packages. wheel Build wheels from your requirements. hash Compute hashes of package archives. completion A helper command used for command completion. help Show help for commands. General Options: -h, --help Show help. --isolated Run pip in an isolated mode, ignoring environment variables and user configuration. -v, --verbose Give more output. Option is additive, and can be used up to 3 times. -V, --version Show version and exit. -q, --quiet Give less output. Option is additive, and can be used up to 3 times (corresponding to WARNING, ERROR, and CRITICAL logging levels). --log <path> Path to a verbose appending log. --proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port. --retries <retries> Maximum number of retries each connection should attempt (default 5 times). --timeout <sec> Set the socket timeout (default 15 seconds). --exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort). --trusted-host <hostname> Mark this host as trusted, even though it does not have valid or any HTTPS. --cert <path> Path to alternate CA bundle. --client-cert <path> Path to SSL client certificate, a single file containing the private key and the certificate in PEM format. --cache-dir <dir> Store the cache data in <dir>. --no-cache-dir Disable the cache. --disable-pip-version-check Don't periodically check PyPI to determine whether a new version of pip is available for download. Implied with --no-index. --no-color Suppress colored output
Ps: 若沒有配置，命令行使用其他源安裝：
pip install numpy.py -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
