PyCharm 2018.1 EAP 9

Ernst Haagsman

This week’s EAP version is now available: get it now from our website.

New in PyCharm

Flask Run Configuration

Flask Run Configuration

If you’ve been using a recent version of Flask, you may have already used the `flask run` commands to start your development server. PyCharm now comes with a special run configuration type to make use of Flask’s new functionality. Try it now!

Further Improvements

  • In the previous EAP, in some cases, the sudo password was asked upon creation of a new virtualenv. This bug has been resolved.
  • Various improvements to the ‘Add type hint’ intentions. To have PyCharm suggest a type hint, just put your cursor on a variable, press Alt+Enter, and choose one of the options.
  • The scroll behavior in the built-in terminal (Alt+F12) has been improved.
  • Read more about new features in the release notes


Download this EAP from our website. Alternatively, you can use the JetBrains Toolbox App to stay up to date throughout the entire EAP.

If you’re on Ubuntu 16.04 or later, you can use snap to get PyCharm EAP, and stay up to date. You can find the installation instructions on our website.

PyCharm 2018.1 is in development during the EAP phase, therefore not all new features are already available. More features will be added in the coming weeks. As PyCharm 2018.1 is pre-release software, it is not as stable as the release versions. Furthermore, we may decide to change and/or drop certain features as the EAP progresses.

All EAP versions will ship with a built-in EAP license, which means that these versions are free to use for 30 days after the day that they are built. As EAPs are released weekly, you’ll be able to use PyCharm Professional Edition EAP for free for the duration of the EAP program, as long as you upgrade at least once every 30 days.

    I got round to trying the new Flask Run support today in the latest IntelliJ release which includes version 2018.1.181.3986.9 of the Python plugin – running a Flask server went fine, but unfortunately trying to start a Debug session gave an error:

    FLASK_ENV = development
    In folder /Users/tim/workspace/my-l1nda-backend
    /Users/tim/.virtualenvs/my-l1nda-backend-Gk8rSifq/bin/python -m flask run “/Users/tim/Library/Application Support/IntelliJIdea2018.1/python/helpers/pydev/” –multiproc –qt-support=auto –client –port 49401 –file
    Error: no such option: –multiproc

    Process finished with exit code 2

    Tried out this feature today. Starting my flask app with flask run works fine. But I have several custom cli commands. As far as I can tell there is no way to remove the run command so that my custom cli commands can be used. As an example I run my tests with the cli command “flask test” but if I add an argument to pycharm’s run configuration it outputs “flask run test”.
