mysql-connector won't import into script in pycharm

问题

I have successfully installed mysql-connector using pip.

Installing collected packages: mysql-connector
Running setup.py install for mysql-connector ... done
Successfully installed mysql-connector-2.1.6

However, in PyCharm when I have a script that uses the line:

import mysql-connector

PyCharm gives me an error saying there isn't a package called "mysql" installed. Is there some sort of syntax that should be used to indicate that the entire package name contains the "-" and is not just "mysql"?

When I run my script in IDLE, mysql.connector imports just fine. (I changed it to mysql-connector after seeing the "-" in the name of the package and having trouble in PyCharm.)

EDIT: per @FlyingTeller's suggestions, in the terminal, "where python" returns C:...Programs\Python\Python36-32\python.exe. "where pip" returns ...Python\Python36-32\Scripts\pip.exe. The interpreter in PyCharm for this project is this same filepath & exe as "where python" in the terminal.

Per @Tushar's comment, this program isn't using a virtual environment and the mysql-connector library is already present in the Preferences->Project->Python Interpreter.

Thanks for the feedback and any additional guidance you may be able to provide.

回答1:

You need to import the connector as

import mysql.connector

Check the examples in the docs for this

If that doesn't work, then there might be an inconsistency between the interpreter that pycharm uses and the one you installed the package for. In pycharm, go to

File->Settings->Project Interpreter

In the terminal, enter

where python #Windows
which python #Linux

and also

where/which pip

make sure that the interpreter configured in pycharm is the same that appears when typing which/where python in the command line/shell. Also make sure that pip also points to the same python distribution.

It may be because you are using a virtual environment inside pyCharm, while you might have installed the library using system's default pip.

Check Preferences->Project->Python Interpreter inside Pycharm, and see if your library is listed there. If not, install it using + icon. Normally, if you use pyCharm's inbuilt terminal, it is already using the same virtual env as your project. So using pip there may help.

Usage syntax is as below:

import mysql.connector

conn = mysql.connector.connect(
         user='root',
         password='#####',
         host='127.0.0.1',
         database='some_db')

conn.close()

Go to project interpreter and download mysql-connector.You need to install it also in pycharm
