先说 Mac
按需运行下面的 rm 删除命令
# Configuration
rm -rf ~/Library/Preferences/PyCharm*
# Caches
rm -rf ~/Library/Caches/PyCharm*
# Plugins
rm -rf ~/Library/Application Support/PyCharm*
# Logs
rm -rf ~/Library/Logs/PyCharm*
再来 Windows
找到下面的路径，然后删掉即可
# Windows Vista, 7, 8, 10:
<SYSTEM DRIVE>\Users\<USER ACCOUNT NAME>\.<PRODUCT><VERSION>
# Windows XP:
<SYSTEM DRIVE>\Documents and Settings\<USER ACCOUNT NAME>\.<PRODUCT><VERSION>
