PyCharm 4.0.5 hangs on 'scanning files to inde

问题:

my spec: Intel Core i5-3470 3,2 GHz / 4 GB Ram / I'm using Windows 64 bit. PyCharm 4.0.5

When I launch PyCharm it starts 'scanning files to index' background task and hangs for ~1 hour/forever. From time to time it finishes and proceeds with Updating indices task. It lasts for ~ 3 hours/forever. While this processes are running it is very hard to use PyCharm and even some other programs. PyCharm starts from ~ 200 mb and tooks ~ 1GB of memory at the end of this tasks.

On my laptop, which is much worse. PyCharm launches in 30 sec and ready to work. I'm working on same project on my PC/Laptop

Please, advise.

P.S I don't have simlinks to exclude in my Project Structure

回答1:

My project contained a folder that had like 100k files/folders inside. This was making indexing way too slow.

To fix this, exclude the folder from Project structure in PyCharm.

File - Settings - Project: yourprojectname - Project Structure - Right click on folder and press "Excluded"

I just tried the following:

In PyCharm, go to the "File" on the left top, then select "invalidate caches/restart...", and press "Invalidate and restart".

After that, it can finish scanning in a short period without hanging anymore.

I've already answered this question on Stackoverflow, so I'll just copy and paste... I had the same problem and "File | Invalidate Caches/Restart" had not helped because Pycharm didn't respond at all. I found ".Pycharm50" directory in my home directory -- it contains configuration files. After its removal Pycharm launched as if you've just downloaded it, everything still goes well.

Late answer but this may help other people in the future. For me this issue was fixed by raising the inotify watches limit. After raising it as described on jetbrains their website (https://confluence.jetbrains.com/display/IDEADEV/Inotify+Watches+Limit) it worked properly.

1. Add the following line to either /etc/sysctl.conf file or a new *.conf file (e.g. idea.conf) under /etc/sysctl.d/ directory:

fs.inotify.max_user_watches = 524288

2. Then run this command to apply the change:

sudo sysctl -p --system

I ended up going to the .idea folder of the project and deleting it in order to keep it from hanging when it starts. Then made any appropriate changes to keep it from indexing unnecessary files.

Deleting and reinstalling Pycharm 4.0.5 fixed this for me.
