安装flask-mysql python模块时出错

Question

I'm trying to install the flask-mysql module and am running into an error. It looks like a problem with vcvarsall.bat, but I'm not really sure what that hints at.

Any ideas from someone more experienced than myself?

C:\eb-virt\bucketlist>pip install flask-mysql

Answer 1

You could try using these binaries for windows distributions. Flask-mysql uses mysql-python which has issues when trying to install on windows. See this .

Answer 2

Often this type of error occurred when you have installed python 32bit and mysql 64bit or vice versa. Try out same installations. I have experienced this error with postgresSql and python on this command pip install psycopg2 May be this will solve you issue.
