Yeah this is still an issue in the latest Hyperterm, regardless of the plugins.
Any fixes for this? I keep getting this error pop-up every time I open/re-open Hyper. Tried everything, removed all plugins, uninstalled Hyper and installed again, reinstalled node & npm. Still no luck.

I’m still getting this issue on win10 and hyper 3.0.2 😦
hyperline will cause that warning.
I had this issue (twice - once for my mac mini m1 and once for my macbook air m1) For me it was a permissions problem. I noticed that because every time I had to do a npm install / yarn add I got EACCES permission denied, I had to sudo everything - turns out that this was also messing up the ability of hyper to install plugins as well.
try doing this:
chown -R yourusername /users/yourusernamethat solved the above issues I was having on my m1 mac
I had the same problem here.
The problem is complicated to discover, but it is more than obvious.
We install “hyper” on Windows, via Windows, and then we want to install plugins etc via WSL (Bash Linux). It will not work!
To resolve, go back to the default configuration of Hyper (deleting “.hyper.js” for example) where it will open with the “cmd” Windows again. Install all the plugins you want (with “hyper install hypercwd” for example), and only after that, you change to WSL.
Applause! kkkkkkkkkkk
Just to confirm, I tried most of the solutions above - instaling both npm and hyper via brew did it for me too.
In Mac OS I solved it by just installing npm with brew.
@Ryan315. I disabled hyperline and still getting the warning…
3.1.0 canary1 works for me so far, I’m on macOS Mojave 10.14.6 and I’ve got hyperline & hyper-search plugins successfully running 👍
turn of your plugins please
