一、去官網下載Anaconda，我下載的是Anaconda3

二、安裝Anaconda3

1、下載完成後命令列進入 Anaconda3-5.3.1-Linux-x86_64.sh 所在的路徑：

[email protected]:~/Downloads$ bash Anaconda3-5.3.1-Linux-x86_64.sh 
Welcome to Anaconda3 5.3.1
In order to continue the installation process, please review the license
agreement.
Please, press ENTER to continue
>>> 
 

然後根據提示，按回車確認。
它會提示你是否接受協議，這裡直接輸入yes，再按回車即可（不要直接按回車，這樣預設是no）

Do you accept the license terms? [yes|no]
[no] >>> yes

接下來會提示你指定安裝路徑，這裡可以使用預設的，也可以自己指定，最好自己指定檔案路徑，方便以後維護

Anaconda3 will now be installed into this location:
/home/vision/anaconda3

  - Press ENTER to confirm the location
  - Press CTRL-C to abort the installation
  - Or specify a different location below

[/home/vision/anaconda3] >>> /home/vision/Softwares/Anaconda3
 

然後就是等待安裝程序完成，完成後會提示你是否要將Anaconda的安裝路徑新增到PATH環境變數中，必須輸入yes（不要直接按回車，這樣預設是no），否則需要自己設定環境變數。

installation finished.
Do you wish the installer to prepend the Anaconda3 install location
to PATH in your /home/hj/.bashrc ? [yes|no]
[no] >>> yes

配置後的環境遍歷如下：

# added by Anaconda3 5.3.1 installer
# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/home/vision/Softwares/Anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/home/vision/Softwares/Anaconda3/etc/profile.d/conda.sh" ]; then
        . "/home/vision/Softwares/Anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/home/vision/Softwares/Anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda init <<<
 

之後就是等待安裝完成，Anaconda3 安裝完成提示是否安裝VSCode，這裡選擇yes。如下：

For this change to become active, you have to open a new terminal.

Thank you for installing Anaconda3!

===========================================================================

Anaconda is partnered with Microsoft! Microsoft VSCode is a streamlined
code editor with support for development operations like debugging, task
running and version control.

To install Visual Studio Code, you will need:
  - Administrator Privileges
  - Internet connectivity

Visual Studio Code License: https://code.visualstudio.com/license

Do you wish to proceed with the installation of Microsoft VSCode? [yes|no]
>>> 


Do you wish to proceed with the installation of Microsoft VSCode? [yes|no]
>>> yes
Proceeding with installation of Microsoft VSCode
VSCode is already installed!

三、驗證Anaconda3是否安裝成功

重新開啟一個終端，輸入pyhton

[email protected]:~$ python
Python 3.7.0 (default, Jun 28 2018, 13:15:42) 
[GCC 7.2.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 

如上圖所示, python環境已經自動由Anaconda進行託管

四、Anaconda3的解除安裝

1、刪除整個anaconda目錄： 
由於Anaconda的安裝檔案都包含在一個目錄中，所以直接將該目錄刪除即可。到包含整個anaconda目錄的資料夾下，刪除整個Anaconda目錄：

rm -rf Anaconda3安裝路徑

2、清理下.bashrc中的Anaconda路徑：

開啟終端並輸入： 

sudo gedit ~/.bashrc

在.bashrc檔案末尾，刪除掉Anaconda3寫入的東西

# added by Anaconda3 5.3.1 installer
# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/home/vision/Softwares/Anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/home/vision/Softwares/Anaconda3/etc/profile.d/conda.sh" ]; then
        . "/home/vision/Softwares/Anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/home/vision/Softwares/Anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda init <<<

儲存並關閉檔案

3.使其立即生效，在終端執行： 
source ~/.bashrc

4.關閉終端，然後再重啟一個新的終端，這一步很重要，不然在原終端上還是繫結有Anaconda3.
