Hi, image resizing isn’t working for me. Just trying out Ghost and I really like it so far, but I’m not very familiar with Node. Thanks!

I was able to figure it out myself - a failed attempt to update node after installing ghost caused all kinds of problems. I ended up doing an uninstall/reinstall and everything is working OK so far.

I was able to solve this issue with some installation of missing packages:

I run into a similar issue, i manage to install sharp on the server through npm, however, when i then want to upload the image, ghost still states that sharp isn’t installed.

How can i make the installation apply to ghost?

I solved the issue by updating to ghost v5.42.2. from v5.42.1 with installing sharp through NPM before updating.

To anyone still not understanding what to do (I looked for the answer for a solid two days) you need to install, using the root user, sharp to the /var/www/ghost directory. So:

cd /var/www/ghost
npm install sharp

these two commands solved the issue for me, using the root user.
