PyCharm 2022.2 Help

Project security

To prevent potential security risks, PyCharm lets you decide how to open a project if you're not sure about its source. PyCharm warns you about tasks or configurations that will be executed during the opening process and lets you configure sources that you can trust.

Open a project from unknown sources

When you open any project, PyCharm immediately lets you decide how to handle a project that contains unfamiliar source code.

Trust Project dialog

You can select one of the following actions:

  • Preview in Safe Mode: in this case PyCharm opens a project in a "preview mode" meaning you can browse the project's sources, but there are restrictions in running any scripts or projects..

    For more information on Safe Mode preview limitations, refer to Safe mode preview limitations.

    PyCharm displays a notification on top of the editor area, and you can click the Trust project… link and load your project at any time.

  • Trust Project: in this case, PyCharm opens and loads a project. That means project is initialized, project's plugins are resolved, dependencies are added, and all PyCharm features are available.

  • Don't Open: in this case PyCharm cancels the action.

Startup tasks

When you open a project created on a different machine, it might contain some scripts or tasks that are executed during the opening process. If such tasks are found, PyCharm displays a notification suggesting that the code you are about to execute might be harmful.

You can review what tasks will be executed and modify the settings.

Review the startup tasks

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), go to Tools | Startup Tasks.

  2. On the Startup Tasks settings page, you can review and modify the startup tasks.

Safe mode preview limitations

If you open a project in the safe mode, the following limitations will apply to the project:

  • : any scripts or tasks that are executed during the opening process are disabled.

  • VCS support: the whole VCS support is disabled.

  • GDSL scripts: any Groovy DSL scripts will not be executed.

  • File Watchers scripts will not wake up and run corresponding tools.

Trusted locations

You can configure what sources PyCharm should consider safe and load such projects automatically during the opening process.

You can add your home directory to the trusted locations to disable PyCharm's warnings about untrusted projects.

Configure trusted locations

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), go to Build, Execution, Deployment | Trusted Locations.

  2. On the Trusted Locations settings page, configure the local directories where the projects you consider trusted reside. Click OK to save the changes.

    Trusted Locations

    The next time you open a project from one of those locations, PyCharm will automatically load the project.
