ANSWER
Answered 2021-Jun-14 at 15:41Well there could be multiple issues with your environment, which does not allow SSL connections, since the tool cannot accept the certificates.
Another approach could be to turn off the SSL verification, as long as you working on a development machine.

Answered 2021-Jun-07 at 16:57Couple things to check:
- Can you connect to MySQL outside of the script with the credentials
you provided (
mysql -u root -p
)? If yes, then there may be a configuration problem in your script to connect. If not, confirm MySQL is running, then re-check your password. If a potential password issue, may be worth restarting MySQL by addingskip_grant_tables
under your configuration file and restarting so you can log in w/o a password and reset the root password. - Did you modify the MySQL configuration in any way, specifically the
bind-address
? By default, MySQL sets this to 127.0.0.1, so you may want to try connecting with 127.0.0.1 instead of localhost. - If this is a non-Windows machine, is /etc/hosts configured properly for localhost (ex:
127.0.0.1 localhost
)?
I use a different method to connect to MySQL via Python, so I am not as familiar with sqlalchemy.

- Find the package
I looked at that post
- Add it to sys.path (which will also add it to PYTHONPATH)

**I use Flutter Downloader Package After complete download some file , my app closes automatically and disconnecte to the android studio. Any one help me to find soltutions.
...ANSWER
Answered 2021-Jun-07 at 08:14Maybe it late but it may help others. Recently I faced this error and I solved it. Your UI is rendering in Main isolate and your download events come from background isolate. Because codes in callback are run in the background isolate, so you have to handle the communication between two isolates. Usually, communication needs to take place to show download progress in the main UI. Implement the below code to handle communication:

Install downloader
You can use downloader like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
