数据玩物、代码屋、1/0游戏：（零和博弈）/ 禅宗意志 / 规则战争 / 解放数据力量 / 技术的飞速发展并没有改变这个世界，因为，这个世界从没有变，它只是越来越趋近于它本来的模样。
Linux的操作系统在装好后，默认会带Python2的支持。
但是，并没有包含PIP的支持。
因此，PIP需要自行安装。
但是，如果你的Python是2的版本，你想要安装PIP，直接运行【get-pip.py】很可能会遇到各种问题：
1. http://d-prototype.com/archives/13663
2. http://d-prototype.com/archives/13664
正确的做法是，下载对应的Python版本的【get-pip.py】的脚本。
如果你觉得这个过程很烦，.. 那么你可以用我的脚本自动的去安装：
脚本执行效果如下：[……]
在Linux中，我们通常会用以下的方法去重建一批文件：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 |
[root@localhost script]# pwd /script [root@localhost script]# [root@localhost script]# ls -ltr total 0 [root@localhost script]# [root@localhost script]# mkdir -p the_world/{human/{iron_man},angel,god/{thorns,odin}} [root@localhost script]# [root@localhost script]# tree ../script/ ../script/ └── the_world ├── angel ├── god │ ├── odin │ └── thorns └── human └── {iron_man} 7 directories, 0 files [root@localhost script]# [root@localhost script]# mkdir -p numbers/{1,2,3,4,5,6} [root@localhost script]# [root@localhost script]# tree ../script/ ../script/ ├── numbers │ ├── 1 │ ├── 2 │ ├── 3 │ ├── 4 │ ├── 5 │ └── 6 └── the_world ├── angel ├── god │ ├── odin │ └── thorns └── human └── {iron_man} 14 directories, 0 files [root@localhost script]# |
假设场景：
1. 我需要创建文件名连续的一组文件
2. 但是因为数量过大，我不能够一一列出来
比较正常的思路是通过【for】循环来实现。
这种方式是一定可以做到的。
但是有没有更简单的方法？比如在一行命令中实现？
有。
下面来具体演示一下。
先看看错误的例子：
|
1 2 3 4 5 6 7 8 |
[root@localhost script]# touch {$(seq -s "," 1 10)} [root@localhost script]# [root@localhost script]# ls -ltr total 8 drwxr-xr-x 5 root root 4096 May 14 07:06 the_world drwxr-xr-x 8 root root 4096 May 14 07:07 numbers -rw-r--r-- 1 root root 0 May 14 07:10 {1,2,3,4,5,6,7,8,9,10} [root@localhost script]# |
正确的方式是这样的：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |
[root@localhost script]# pwd /script [root@localhost script]# [root@localhost script]# touch $(seq 1 10) [root@localhost script]# [root@localhost script]# ls -ltr total 0 -rw-r--r-- 1 root root 0 May 14 07:11 9 -rw-r--r-- 1 root root 0 May 14 07:11 8 -rw-r--r-- 1 root root 0 May 14 07:11 7 -rw-r--r-- 1 root root 0 May 14 07:11 6 -rw-r--r-- 1 root root 0 May 14 07:11 5 -rw-r--r-- 1 root root 0 May 14 07:11 4 -rw-r--r-- 1 root root 0 May 14 07:11 3 -rw-r--r-- 1 root root 0 May 14 07:11 2 -rw-r--r-- 1 root root 0 May 14 07:11 10 -rw-r--r-- 1 root root 0 May 14 07:11 1 [root@localhost script]# [root@localhost script]# touch $(seq -f 'file_%g' 1 10) [root@localhost script]# [root@localhost script]# ls -ltr total 0 -rw-r--r-- 1 root root 0 May 14 07:17 file_9 -rw-r--r-- 1 root root 0 May 14 07:17 file_8 -rw-r--r-- 1 root root 0 May 14 07:17 file_7 -rw-r--r-- 1 root root 0 May 14 07:17 file_6 -rw-r--r-- 1 root root 0 May 14 07:17 file_5 -rw-r--r-- 1 root root 0 May 14 07:17 file_4 -rw-r--r-- 1 root root 0 May 14 07:17 file_3 -rw-r--r-- 1 root root 0 May 14 07:17 file_2 -rw-r--r-- 1 root root 0 May 14 07:17 file_10 -rw-r--r-- 1 root root 0 May 14 07:17 file_1 [root@localhost script]# |

问题如题所示，它发生在我的以下环境中：
Python：编译安装的【2.6.8】
Linux：RHEL 6.5

错误如题所示，具体如下：
在通过get-pip.py安装PIP的时候遇到错误：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
[root@linux pip]# python2.6 get-pip.py Traceback (most recent call last): File "get-pip.py", line 21492, in <module> main() File "get-pip.py", line 197, in main bootstrap(tmpdir=tmpdir) File "get-pip.py", line 82, in bootstrap import pip._internal File "/tmp/tmpExsnAY/pip.zip/pip/_internal/__init__.py", line 19, in </module><module> File "/tmp/tmpExsnAY/pip.zip/pip/_vendor/urllib3/__init__.py", line 8, in </module><module> File "/tmp/tmpExsnAY/pip.zip/pip/_vendor/urllib3/connectionpool.py", line 92 _blocking_errnos = {errno.EAGAIN, errno.EWOULDBLOCK} ^ SyntaxError: invalid syntax [root@linux pip]# </module> |
原因：
没有根据Python版本，选择正确的get-pip.py的版本。
解法：
从GITHUB上的Pip的官方资料库获得具体版本的get-pip.py的代码：
https://github.com/pypa/get-pip
对于我的当前环境来说，我应该拿的是2.6的git-pip.py的脚本：
