I used pycharm well before, but suddenly it couldn't be opened. I searched for various methods on the Internet, but couldn't solve it. Finally, I solved it by deleting the pycharm.vmoptions file. The specific method is as follows:
1. Find the path where pycharm.vmoptions is stored, usually in /Users/{replace with your own username}/Library/Application Support/JetBrains/PyCharm2021.1
Note: cd 到Application Support时 提示找不到路径的问题
Reason: There is a space between and in /Application Support/this place , which needs to be escaped and replaced withApplicationSupport/Application\ Support/即可
2.删除pycharm.vmoptions file, use the command: rm -r pycharm.vmoptions
After the problem of sudden inability to open is solved, there is another problem, that is, the plug-in used before is unstable and will suddenly become unavailable. This time, the plug-in is solved by infinitely resetting the trial time. The specific method is as follows :
1. Download the plug-in, link: https://pan.baidu.com/s/1eEAA_AtrOrVk9k79LOTKGQ Extraction code: usjp
2. After the download is completed, drag the plug-in directly into the pycharm interface and the plug-in will be automatically installed.
3. After successful installation, Helpthere will be an additional Eval Resetbutton in the menu bar.
After clicking, you can see three options: Auto reset before restart, Reload, and Reset.
Check option: Auto reset before per restart If checked, the trial information will be automatically reset every time you restart/exit the IDE (this is the automatic reset method)
Reload is used to refresh the display information on the interface
Clicking Reset will ask you whether to reset the trial for 30 days and restart the IDE.
Select Yes to perform the reset operation and restart pycharm to take effect.
Select No to do nothing
