The comment on the original question was the solution for me. My "Downloads" folder is hosted on D: and the installer assumes C:

Answer 2

A solution that helped me after transferring the exe to C has failed, is deleting the folder:
C:\Users\{YOUR_PROFILE_NAME}\.cache\firebase
Hope this helps anyone

Answer 3

That is nothing to worry about, it only appears because the CLI by default assumes it is in the C directory.
So, copying the CLI exe to any other directory would show this message but, you can still use all the CLI functionalities as you wish.
Like what I did here using firebase init

Answer 4

The solution :
leave the exe name as: "firebase-win.exe" and you can move it to whatever folder you want
The detailed explanation:
i moved the executable i downloaded ("firebase-tools-instant-win.exe") to folder: c:\firebase\bin
and it works without any error,
but for some reason if i rename the exe file to something like: "firebase.exe" or "fbcli.exe" it will throw the json error and will not download the .cache folder correctly
but if i rename the exe name to: "firebase-win.exe" it works no matter what folder i put it in,
when checking C:\Users{YOUR_PROFILE_NAME}.cache\firebase\runtime\shell.bat
if the exe name is: "firebase.exe" (Not working) then the content is:
#echo off
"C:\firebase\bin\firebase.exe" C:\Users\{YOUR_PROFILE_NAME}\CACHE~1\firebase\runtime\shell.js %*
if the exe name is: "firebase-win.exe" (working) then the content is:
#echo off
"C:\firebase\bin\FIREBA~1.EXE" C:\Users\shaybc\.cache\firebase\runtime\shell.js %*
so i simply left the exe name: "firebase-win.exe"
valid names worked for me:
fireb-win.exe
firebase-win.exe
firebase-w.exe
fire-base.exe
fbcli-win.exe
...

Answer 5

Install Firebase using npm:
npm install firebase

Answer 6

I got this warning as well, but when I tried to init, serve, and deploy, it worked just fine. Good luck!
