Installation of pagoda and deployment of flask project

Deploy flask
I use Pagoda in this way python An error is reported when the project manager is installed , Remind me that I need virtual environment .
Then I heard that the boss from afar gave a solution

 To enter the virtual environment and then start 
 Before that, you need to  cd  command   Enter the project directory .
source venv/bin/activate
python app.py

It coincides with the idea of the boss , Then I guess it should be virtual environment （ To isolate package conflicts ）.

Linux Build build python A virtual environment ：

Just run the command line given to me by the boss from afar .
There is a book in the Group flask Your books should also write .
But I don't know why every time There will be database errors .
Restart and then access .
Checked some relevant information , Should be Database connection problem .
If the database reports an error , Restart the service every time .

Install the reference
