Python 安裝requests和MySQLdb

0.系統版本

0.1 檢視系統版本

1 [root@localhost ~]# uname -a
2 Linux localhost.localdomain 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

1.安裝requests

1.1 軟體下載

1 [root@localhost ~]# wget 
2 https://pypi.python.org/packages/b0/e1/eab4fc3752e3d240468a8c0b284607899d2fbfb236a56b7377a329aa8d09/requests-2.18.4.tar.gz#md5=081412b2ef79bdc48229891af13f4d82

1.2 解壓

1 [root@localhost ~]# tar xf requests-2.18.4.tar.gz

1.3安裝requests

1 [root@localhost ~]# cd requests-2.18.4
2 [root@localhost requests-2.18.4]# python setup.py install

1.4 安裝報錯

1 [root@1e supervisor-3.0]# python setup.py install  
2 Traceback (most recent call last):  
3   File "setup.py", line 31, in <module>  
4     from setuptools import setup, find_packages  
5 ImportError: No module named setuptools

原因是沒有找到setuptools包，再次安裝這個包

下載setuptools :

1 [root@localhost requests-2.18.4]#wget 
2 https://pypi.python.org/packages/a4/c8/9a7a47f683d54d83f648d37c3e180317f80dc126a304c45dc6663246233a/setuptools-36.5.0.zip#md5=704f500dd55f4bd0be905444f3ba892c

利用unzip進行解壓

1 [root@localhost requests-2.18.4]# unzip setuptools-36.5.0.zip

如果提示沒有找到unzip命令，則利用yum安裝即可

1 [root@localhost requests-2.18.4]# yum install zip unzip

解壓完成後即可進行安裝

1 [root@localhost requests-2.18.4]# cd setuptools-36.5.0
2 [root@localhost setuptools-36.5.0]# python setup.py install

安裝完成後即可進行安裝requests

1 [root@localhost setuptools-36.5.0]# cd ../
2 [root@localhost requests-2.18.4]# python setup.py install

安裝完成檢驗，進入python互動式介面進行匯入包即可

[root@localhost requests-2.18.4]# python
Python 2.7.5 (default, Nov 6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2

>>> import requests
>>>

2.安裝requests

2.1 軟體下載

1 [root@localhost ~]# wget 
2 https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip#md5=654f75b302db6ed8dc5a898c625e030c

2.2 解壓並且安裝

1 [root@localhost ~]# unzip MySQL-python-1.2.5.zip 
2 [root@localhost ~]# cd MySQL-python-1.2.5
3 [root@localhost MySQL-python-1.2.5]# python setup.py install

2.3 安裝報錯

sh: mysql_config: not found
Traceback (most recent call last):
File "setup.py", line 15, in <module>
metadata, options = get_config()
File "/home/zhxia/apps/source/MySQL-python-1.2.3/setup_posix.py", line 43, in get_config
libs = mysql_config("libs_r")
File "/home/zhxia/apps/source/MySQL-python-1.2.3/setup_posix.py", line 24, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found

安裝libmysqlclient-dev

1 [root@localhost MySQL-python-1.2.5]# yum install libmysqlclient-dev

安裝報錯，並沒有發現libmysqlclient-dev包

[root@localhost requests-2.18.4]# yum install libmysqlclient-dev
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.sohu.com
* extras: mirrors.sohu.com
* updates: mirrors.sohu.com
No package libmysqlclient-dev available.
Error: Nothing to do
[root@localhost requests-2.18.4]#

之所以會出現如下原因是系統沒有找到mysql的依賴包,那麼我們可以自己安裝依賴，這兒依賴可以為mysql 也可以為mariadb

[root@localhost MySQL-python-1.2.5]# yum list all | grep mariadb | grep dev
mariadb-devel.x86_64 1:5.5.56-2.el7 @base
mariadb-embedded-devel.x86_64 1:5.5.56-2.el7 @base
mariadb-devel.i686 1:5.5.56-2.el7 base
mariadb-embedded-devel.i686 1:5.5.56-2.el7 base
[root@localhost MySQL-python-1.2.5]#

安裝mariadb的dev包

1 [root@localhost MySQL-python-1.2.5]# yum install mariadb-devel mariadb-embedded-devel

再次安裝MySQL-python-1.2.5

[root@localhost MySQL-python-1.2.5]# python setup.py install

再次報錯

再次安裝python-devel

1 [root@localhost MySQL-python-1.2.5]# yum install python-devel

再次嘗試

1 [root@localhost MySQL-python-1.2.5]# python setup.py install

檢測是否安裝OK

[root@localhost MySQL-python-1.2.5]# python

安裝requests和MySQLdb到此結束
