Can't install MM on brand new Pi4
-
Hi all, brand new to MM and fairly new to Pi here. I tried a manual install of MM as well as the auto installer from @sdetweil and both failed. I completely reformatted my brand new SD card and did a fresh install of Raspbian and tried the auto installer again, and am getting the same errors.
I’ve noticed a few errors during the install process that may help troubleshoot, but I’m not sure how to fix them. Any help would be very much appreciated!
During the install dependencies:
Error: Generated checksum for "electron-v6.1.12-linux-armv7l.zip" did not match expected checksum. at Hash.hasher.on (/home/pi/MagicMirror/node_modules/sumchecker/index.js:151:20) at Hash.emit (events.js:198:13) at emitReadable_ (_stream_readable.js:555:12) at process._tickCallback (internal/process/next_tick.js:63:19) npm notice created a lockfile as package-lock.json.

Run pm2 start MagicMirror[…]” message and it shows “status” as online, but then nothing happens. If I try “npm start” from the MM directory, I get this error:

@sdetweil thanks for your reply! Sure, here you go (from the log):

@sdetweil and this is from the terminal above the checksum error, after it finishes cloning MM:

@Diminished7th fun, try this
cd ~/MagicMirror npm remove electron npm install electron@6.1.12 -
@sdetweil no joy. Still getting what appears to be the same error:

A complete log of this run can be found in: npm ERR! /home/pi/.npm/_logs/2020-07-16T16_06_11_241Z-debug.logIt does look like when it’s trying to download the .zip file it’s getting hung up somewhere. I tried the install 5 or 6 times and each time the download progress will “pause” at a different point, sometimes around 13%, sometimes 20% or 30%, it’ll hang there and then jump to 100%. Not sure if this means something.
Is there a way to download the file locally and install that way to ensure it’s being downloaded completely? Should I try a different version of electron?
-
@Diminished7th how is the pi connected to the internet?, wired, wifi?
have u rebooted your router -
@sdetweil it’s on wifi. I rebooted the modem and router last night during troubleshooting. I can browse the internet while it’s downloading so the internet appears to be functioning properly. I can unhook everything and wire it up to the router if you think that will help?
-
@sdetweil your first response seems to have been correct! It appears it is some issue with the network. For some reason, it will begin to download the .zip file, but not complete it each time. It’s not that the network is going down because it doesn’t lose connection. Maybe something with the router’s firewall?
Anyways, I connected the Pi to my phone hotspot and ran the electron install, and it completed just fine and I am up and running.
If anyone else is having this issue, the telltale sign is the progress bar getting hung up before 100% and then quickly jumping to 100% and then immediately throwing the checksum error.
Thanks to @sdetweil for the troubleshooting tips! I will be marking as solved!!
EDIT: Guess I can’t mark as solved. I’ll just let the thread die. :)
