python 3.7安装：Linux(Ubuntu 18.04)

Linux安装

Anaconda是最受欢迎的python数据科学和机器学习平台，用于大规模数据处理，预测分析和科学计算。Anaconda发行版附带了1,000多个数据包，conda命令行工具和Anaconda Navigator的桌面图形用户界面。一般而言，使用Anaconda比直接使用官方的python更好用。

本教程将指导您完成在Ubuntu 18.04上下载和安装Anaconda Python Distribution。通常也适合多数其他Linux。

下载Anaconda

https://www.anaconda.com/download/#linux

在撰写本文时，Anaconda的最新稳定版本是5.3版本。

请选择64-Bit (x86) Installer 进行下载，尽量不要用python2.7，很多库已经不提供python2.7支持。

点击链接就会进行下载，同时会弹出信息收集框，直接关闭就好。

Do you wish to proceed with the installation of Microsoft VSCode? [yes|no] #选择no，一般来说自带的spyder和专业IDE wingIDE更好用。
...
Do you wish the installer to initialize Anaconda3
in your /home/andrew/.bashrc ? [yes|no]
[no] >>> # 选择yes
Initializing Anaconda3 in /home/andrew/.bashrc
A backup will be made to: /home/andrew/.bashrc-anaconda3.bak


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]
>>> no

添加“export PATH=/usr/local/anconda3/bin:$PATH“ 到/etc/profile，这样所有用户都可以使用Anaconda python3.7了。

上面的.bashrc在刚才安装时添加了如下内容：

# added by Anaconda3 5.3.0 installer
# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/usr/local/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/usr/local/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/usr/local/anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/usr/local/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup~/.bashrc
# <<< conda init <<<

验证安装

通过重新登陆或者执行'source ~/.bashrc"加载环境变量。

$ conda info

至此，已经安装完毕。

更新Anaconda

一般是有新版本发布时才需要使用。

$ conda update conda
$ conda update anaconda

删除Anaconda

一般是有新版本发布时才需要使用。

$sudo rm -rf /usr/local/anaconda3
删除上面~/.bashrc和/etc/profile的修改
清空隐藏文件： rm -rf ~/.condarc ~/.conda ~/.continuum
