@sunqi your redis version is out of date by the looks of it as pexpire is supported by 2.6 and up.

I had the same issue, follow the progress here.

[julian]

Yup, minimum requirement is Redis 2.6.0 now (has been for awhile, but it was only a soft requirement -- now it's a hard requirement)

@julian @a_5mith i just followed the digitalocean installing instructions to set up my nodebb
is there any guides about updating my redis？

@sunqi

sudo apt-get install -y python-software-properties
sudo add-apt-repository -y ppa:rwky/redis
sudo apt-get update
sudo apt-get install -y redis-server

The -y saves you having to confirm when it asks if you want to install.
