My pycharm version is pycharm2020.1.1, and I use ssh to log in remote server. But there was an warning Couldn't upload helpers for remote interpreter: File:/Library/Caches/JetBrains/PyCharm2020.1/remote_sources/858584654/-733841145/.pycharm_helpers/packaging_tool.py: Permission denied . I check the permissions of .pycharm_helpers and its subfile in local and remote server. The permission of all the file and directory are rwxrwxrwx. I don't know why it still don't have permission. And when I click a function, it will redirect to the file in /Library/Caches/JetBrains/PyCharm2020.1/remote_sources/, not in my project.
