python - (Python 3.6.1) Pandas df 到 MySQL 数据库错误， 'ModuleNotFoundError: No module named ' MySQLdb'

Question

我有一个 .csv 文件，我想首先将其存储在 pandas 数据框中，然后导入到 MySQL 数据库表中。

我已按照此帖子进行初始设置:pandas dataframe to mysql db error database flavor mysql is not supported

我的.py代码如下:

from sqlalchemy import create_engine
import pandas

engine = create_engine("mysql+mysqldb://root:password@locahost/new_schema")

df = pandas.read_csv('items.csv')
df.to_sql('items', con=engine, flavor='mysql', if_exists='append')

我收到的错误消息是这样的:

/PyCharmProjects/venv2/bin/python /PyCharmProjects/venv2/tutorial/tutorial/other/csvToMySQL.py
Traceback (most recent call last):
  File "/PyCharmProjects/venv2/tutorial/tutorial/other/csvToMySQL.py", line 4, in <module>
    engine = create_engine("mysql+mysqldb://root:password@locahost/new_schema")
  File "/PyCharmProjects/venv2/lib/python3.6/site-packages/sqlalchemy/engine/__init__.py", line 387, in create_engine
    return strategy.create(*args, **kwargs)
  File "/PyCharmProjects/venv2/lib/python3.6/site-packages/sqlalchemy/engine/strategies.py", line 80, in create
    dbapi = dialect_cls.dbapi(**dbapi_args)
  File "/PyCharmProjects/venv2/lib/python3.6/site-packages/sqlalchemy/dialects/mysql/mysqldb.py", line 110, in dbapi
    return __import__('MySQLdb')
ModuleNotFoundError: No module named 'MySQLdb'

我的引擎设置做错了什么？

技术规范:

• Mac OSX 10.11 (El Capitan)
• Python 3.6.1
• PyCharm CE 2017.1.2
• 5.7.18 MySQL 社区服务器 (GPL)

我根据下面的建议尝试了“pip install MySQL-python”。这是我收到的错误:

Collecting MySQL-python
  Using cached MySQL-python-1.2.5.zip
    Complete output from command python setup.py egg_info:

我根据下面的建议尝试了“pip install mySQLdb”。这是我收到的错误:

Collecting MySQLdb
  Could not find a version that satisfies the requirement MySQLdb (from versions: )
No matching distribution found for MySQLdb

经过多次尝试，我终于找到了使用Python 3.6.1快速工作的方法。显然，完成此任务的最快方法是使用 Homebrew 安装 mySQL，然后安装 mysql 客户端。我最初是通过.dmg安装MySQL的，在安装各种软件包时遇到了很多错误。

在终端中，输入:

• $brew 安装 mySQL
• $pip 安装 mysqlclient

.py 代码现在可以运行:

from sqlalchemy import create_engine
import pandas

engine = create_engine("mysql+mysqldb://root:password@locahost/new_schema")

df = pandas.read_csv('items.csv')
df.to_sql('items', con=engine, if_exists='append')

(仅供引用，我从原始代码中删除了“flavor = mysql”，因为它不是一个可识别的参数 - 请参阅 https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_sql.html#pandas-dataframe-to-sql )
