python之解决pycharm：External file changes sync may be slow: The current inotify

1.检查当前设置

$ cat /proc/sys/fs/inotify/max_user_watches

8192

2.当前值太小，添加新的conf文件， 打开文件并添加以下内容：

# Set inotify watch limit high enough for IntelliJ IDEA (PhpStorm, PyCharm, RubyMine, WebStorm).
# Create this file as /etc/sysctl.d/60-jetbrains.conf (Debian, Ubuntu), and
# run `sudo service procps start` or reboot.
# Source: https://confluence.jetbrains.com/display/IDEADEV/Inotify+Watches+Limit
# 
# More information resources:
# -$ man inotify # manpage
# -$ man sysctl.conf # manpage
# -$ cat /proc/sys/fs/inotify/max_user_watches # print current value in use

fs.inotify.max_user_watches = 524288

3.重新启动系统

$ sudo sysctl -p --system
