0.系统版本
0.1 查看系统版本
[root@localhost ~]# uname -a Linux localhost.localdomain -.el7.x86_64 # SMP Tue Nov :: UTC x86_64 x86_64 x86_64 GNU/Linux
1.安装requests
1.1 软件下载
[root@localhost ~]# wget \ https://pypi.python.org/packages/b0/e1/eab4fc3752e3d240468a8c0b284607899d2fbfb236a56b7377a329aa8d09/requests-2.18.4.tar.gz#md5=081412b2ef79bdc48229891af13f4d82
1.2 解压
[root@localhost ~]# .tar.gz
1.3安装requests
[root@localhost ~]# cd requests- [root@localhost requests-]# python setup.py install
1.4 安装报错
[root@1e supervisor-3.0]# python setup.py install Traceback (most recent call last): File , in <module> from setuptools import setup, find_packages ImportError: No module named setuptools
原因是没有找到setuptools包,再次安装这个包
下载setuptools :
[root@localhost requests-]#wget \ https://pypi.python.org/packages/a4/c8/9a7a47f683d54d83f648d37c3e180317f80dc126a304c45dc6663246233a/setuptools-36.5.0.zip#md5=704f500dd55f4bd0be905444f3ba892c
利用unzip进行解压
[root@localhost requests-]# .zip
如果提示没有找到unzip命令,则利用yum安装即可
[root@localhost requests-]# yum install zip unzip
解压完成后即可进行安装
[root@localhost requests-]# cd setuptools- [root@localhost setuptools-]# python setup.py install
安装完成后即可进行安装requests
[root@localhost setuptools-]# cd ../ [root@localhost requests-]# python setup.py install
安装完成检验,进入python交互式界面进行导入包即可
[root@localhost requests-]# python Python (default, Nov , ::) [GCC (Red Hat -)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import requests >>>
2.安装requests
2.1 软件下载
[root@localhost ~]# wget \ https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip#md5=654f75b302db6ed8dc5a898c625e030c
2.2 解压并且安装
[root@localhost ~]# .zip [root@localhost ~]# cd MySQL-python- [root@localhost MySQL-python-]# python setup.py install
2.3 安装报错
sh: mysql_config: not found Traceback (most recent call last): File , in <module> metadata, options = get_config() File , in get_config libs = mysql_config("libs_r") File , in mysql_config raise EnvironmentError("%s not found" % (mysql_config.path,)) EnvironmentError: mysql_config not found
安装libmysqlclient-dev
[root@localhost MySQL-python-]# yum install libmysqlclient-dev
安装报错,并没有发现libmysqlclient-dev包
[root@localhost requests-]# 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-]#
之所以会出现如下原因是系统没有找到mysql的依赖包,那么我们可以自己安装依赖,这儿依赖可以为mysql 也可以为mariadb
[root@localhost MySQL-python-]# yum list all | grep mariadb | grep dev mariadb-devel.x86_64 :-.el7 @base mariadb-embedded-devel.x86_64 :-.el7 @base mariadb-devel.i686 :-.el7 base mariadb-embedded-devel.i686 :-.el7 base [root@localhost MySQL-python-]#
安装mariadb的dev包
[root@localhost MySQL-python-]# yum install mariadb-devel mariadb-embedded-devel
再次安装MySQL-python-1.2.5
[root@localhost MySQL-python-1.2.5]# python setup.py install
再次报错
[root@localhost MySQL-python-]# python setup.py install running install running bdist_egg running egg_info writing MySQL_python.egg-info/PKG-INFO writing top-level names to MySQL_python.egg-info/top_level.txt writing dependency_links to MySQL_python.egg-info/dependency_links.txt reading manifest file 'MySQL_python.egg-info/SOURCES.txt' reading manifest template 'MANIFEST.in' writing manifest file 'MySQL_python.egg-info/SOURCES.txt' installing library code to build/bdist.linux-x86_64/egg running install_lib running build_py copying MySQLdb/release.py -> build/lib.linux-x86_64-2.7/MySQLdb running build_ext building '_mysql' extension -fexceptions -fstack-protector-strong --param=ssp-buffer-size= -grecord- -fexceptions -fstack-protector-strong --param=ssp-buffer-size= -grecord-,,,) -D__version__= -I/usr/include/mysql -I/usr/include/python2. -c _mysql.c -o build/temp.linux-x86_64-2.7/_mysql.o _mysql.c::: fatal error: Python.h: No such file or directory #include "Python.h" ^ compilation terminated. error: command
再次安装python-devel
[root@localhost MySQL-python-]# yum install python-devel
再次尝试
[root@localhost MySQL-python-]# python setup.py install
检测是否安装OK
[root@localhost MySQL-python-]# python Python (default, Aug , ::) [GCC (Red Hat -)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import MySQLdb /usr/lib64/python2./site-packages/MySQL_python--py2.-linux-x86_64.egg/_mysql.py:: UserWarning: Module _mysql was already imported from /usr/lib64/python2./site-packages/MySQL_python--py2.-linux-x86_64.egg/_mysql.pyc, but /root/python-script/MySQL-python- is being added to sys.path >>>
安装requests和MySQLdb到此结束
