问题
I have flask web application running on aws, my app.py file gives error for "import pymysql" line (whole application is working fine.)
Error.log [Sat Jul 29 06:12:54.545904 2017] [wsgi:error] [pid 28317:tid 140546426812160] [client ] ImportError: No module named pymysql
Python version is -
2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609]
I created test.py file and executed, it worked and displays rows from database which is on RDS , So no idea why same thing is not working on app.py file , both using same python
**$pip list** click (6.7) Flask (0.12.2) Flask-MySQL (1.4.0) itsdangerous (0.24) Jinja2 (2.9.6) MarkupSafe (1.0) pip (8.1.1) PyMySQL (0.7.11) setuptools (20.7.0) Werkzeug (0.12.2) wheel (0.29.0)

回答1:
This bug have also been giving me some grey hair ^^
I use python2 and the solution for me, was to install the package with the command:
sudo apt-get install python-pymysql
If you are using python3, then you can install it with the command:
sudo apt-get install python3-pymysql
回答2:
try the following command.
pip install PyMySQL==0.7.11
What come back?
回答3:
I got the answer
installing with this command did not work $sudo pip install PyMySql
I have to do
$sudo -i
$sudo pip install PyMySql
And it worked...
回答4:
update pip and reinstall PyMySQL
