Can't open Pycharm Console and can't upload helpers for remote interpreter (PyCharm 2021.1 and PyCharm 2021.2)

I am unable to open the Python Console tab in PyCharm 2021.2 (same happened in 2021.1 also). The error is:

Error:Console process terminated with error:
Traceback (most recent call last):

Seems to be something wrong in .pycharm_helpers.

In addition, and possibly related, I regularly get the following error on the Event Log:

Couldn't upload helpers for remote interpreter: File /Users/<username>/Library/Caches/JetBrains/PyCharm2021.1/remote_sources/293810872/46911889/.pycharm_helpers/ /Users/<username>/Library/Caches/JetBrains/PyCharm2021.1/remote_sources/293810872/46911889/.pycharm_helpers/ is not a file or directory

Despite this message, the .pycharm_helpers DO get uploaded to the VM, even after I delete them. 

The directory /Users/<username>/Library/Caches/JetBrains/PyCharm2021.1/remote_sources/293810872/46911889/.pycharm_helpers doesn't exist at all locally, even though on the VM, .pycharm_helpers does exist in the home directory. Also, /Users/<username>/Library/Caches/JetBrains/PyCharm2021.1/remote_sources/293810872/46911889/ contains all the other files from the VM home directory (just not .pycharm_helpers).

I have tried the following:

  • Invalidate caches
  • Delete local caches manually (~/Library/Caches/JetBrains/PyCharm2021.1/)
  • Delete ~/.pycharm_helpers on the VM
  • Delete and recreate Python interpreter

do you by chance access your remote server by multi-hop ssh, using .ssh/config ? I have the same issue with 2021.2 (works with 2021.1).


My connection to the remote server does authenticate via .ssh/config.

Note that since I upgraded to 2021.2, it looks like the directory /Users/<username>/Library/Caches/JetBrains/PyCharm2021.2/remote_sources doesn't exist. The other symptoms of the problem remain the same as described above.



Please upload your logs folder zipped from ***Help | Collect logs and Diagnostic Data***   to the FTP and please let me know the filename.
