yum install python-devel 安装好之后,就是做一个基本的验证,看看模块是否可以正常的加载。 当然还是有点曲折,报错了。 >>> import MySQLdb /usr/lib64/python2.6/site-packages/MySQL_python-1.2.5-py2.6-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/lib64/...

pymysql的预编译 python预编译标准库 为了提高模块加载的速度,每个模块都会在__pycache__文件夹中放置该模块的预编译模块,命名为module.version.pyc,version是模块的预编译版本编码,一般都包含Python的版本号。例如在CPython 发行版3.4中,fibo.py文件的预编译文件就是:__pycache__/fibo.cpython-34.pyc。这种命名...
pipinstallpymysql 1. 该命令会自动下载并安装pymysql模块。安装完成后,我们可以再次运行 “pip list” 命令来确认模块是否已经安装。 步骤三:检查是否存在其他问题 如果pymysql模块已经安装,但仍然出现 “module not found” 错误,那么可能存在其他问题。接下来,我们将逐一检查可能的问题。
To use the C Extension directly, import the_mysql_connectormodule rather thanmysql.connector, then use the_mysql_connector.MySQL()class to obtain aMySQLinstance. For example: import_mysql_connector ccnx=_mysql_connector.MySQL()ccnx.connect(user='scott',password='password',host='127.0.0.1',data...
