pip換源

pip源:
豆瓣：http://pypi.douban.com/simple/
清華：https://pypi.tuna.tsinghua.edu.cn/simple

第一種:暫時性換源

有時候pip下載速度有點慢，可以換成國內源提升一下速度

pip install -i https://pypi.doubanio.com/simple/ 包名 

pip install -i https://pypi.doubanio.com/simple/ flask

第二種:永久換源

永久換源的方法如下:

linux下，修改 ~/.pip/pip.conf (沒有就建立一個)， 修改 index-url，內容如下：

[global]

index-url = https://pypi.tuna.tsinghua.edu.cn/simple

windows下，直接在使用者目錄中建立一個pip目錄，如：C:\Users\miku\pip，新建檔案pip.ini，內容如下

[global]

index-url = https://pypi.tuna.tsinghua.edu.cn/simple

IDE工具

為了提升編碼速度，需要好的編譯器，推薦使用pycharm

以下是pycharm破解,使用2017版本就可以了

Linux中切換python版本

首先先來看一下我們的預設Python版本

$ python --version
Python 2.7.6

然後修改一下別名

$ alias python='/usr/bin/python3'
$ python --version
Python 3.4.3  # 版本已經改變
