Ubuntu系统使用记录

1. 下载 Ubuntu 16.04
http://releases.ubuntu.com/16.04/ubuntu-16.04.2-desktop-amd64.iso

2. 使用virtual Box进行安装

3. 系统版本

4. Python默认版本

5. git

在Linux下输入git，如果出现如下提示

表示没有安装git程序，在Ubuntu下直接使用如下命令安装即可

sudo apt install git

6. pip安装

1）下载

下载地址：https://pypi.python.org/pypi/pip

2）解压

tar zxvf pip-9.0.1.tar.gz

3）安装

pip setup.py install出现如下错误

wxer@wxer:~/Downloads/pip-9.0.1$ python setup.py install
Traceback (most recent call last):
File "setup.py", line 6, in <module>
from setuptools import setup, find_packages
ImportError: No module named setuptools

解决方法：先安装setuptools

下载setuptools，https://pypi.python.org/pypi/setuptools

解压安装：

unzip setuptools-34.3.3.zip

python setup.py install

又出现如下错误

Traceback (most recent call last):
File "setup.py", line 11, in <module>
import setuptools
File "/home/wxer/Downloads/setuptools-34.3.3/setuptools/__init__.py", line 12, in <module>

import pkg_resources
File "/home/wxer/Downloads/setuptools-34.3.3/pkg_resources/__init__.py", line 70, in <module>
import packaging.version
ImportError: No module named packaging.version

以及如下错误：

Traceback (most recent call last):
File "setup.py", line 11, in <module>
import setuptools
File "/home/wxer/Downloads/setuptools-34.3.3/setuptools/__init__.py", line 10, in <module>

需要安装six，packaging 16.8，pyparsing-2.2.0和appdirs 1.4.3之后，安装再安装setuptools即可。
