Since PyCharm 2020.2, Closure Linter support in the IDE has been deprecated, see the Closure Linter official website for details.

However, Closure Linter support is still available through the Closure Linter plugin, which can be installed on the Settings | Plugins page as described in Installing plugins from JetBrains repository.

When Closure Linter support is enabled, PyCharm highlights errors that Closure Linter detects, provides descriptions for them, and suggests quick-fixes where possible.

Descriptions of the errors detected in the current file and quick-fixes for them are available from the editor and from the File tab of the Problems tool window.

Errors in all previously opened files and quick-fixes for them are shown in the Project Errors tab of the Problems tool window. To open the tool window, click the Inspection widget in the upper-right corner of the editor:
