@mrlowndes did u reply yes or no?

[sdetweil]

@sdetweil run the fixuppm2 script from my site

[mrlowndes]

@sdetweil

[sdetweil]

@mrlowndes ok, lets do

sudo npm purge -g pm2 

[mrlowndes]

I don’t think that worked. Tried to paste code but got flagged as spam

[sdetweil]

@mrlowndes
try

sudo npm uninstall -g pm2 

[mrlowndes]

@sdetweil ok done. Now should I try bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)" again?

[sdetweil]

@mrlowndes yes

[mrlowndes]

@sdetweil same result:

pi@raspberrypi:~ $ bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"

@mrlowndes ok, time to get crazy , kill all npm stuff

/cd ~
sudo apt-get purge -y npm 
sudo rm -rf .npm
sudo apt-get install -y npm 
cd MagicMirror
rm -rf node_modules
npm install

then do the fixuppm2 script again

[mrlowndes]

@sdetweil still nothing:

@mrlowndes said in cannot install pm2:

npm ERR! Unexpected end of JSON input while parsing near '…pes/node":"^12.7.

u are getting weird failures…

every time we have seen this, it is the SD card failing.

[mrlowndes]

hmm good question.

[mrlowndes]

@sdetweil should be fine its a SanDisk Ultra Plus 64GB U1 SDXC

[mrlowndes]

@sdetweil if it is the SD card, is it the kind of thing a deep format and reinstall of Raspbian will fix, or is the SD just terminally bad? Wen I reinstalled Raspbian the last time, I did just do a quick format on this card before flashing the image.

[sdetweil]

@mrlowndes when the sd card starts to fail, it is toast

[mrlowndes]

@sdetweil bummer - it’s brand new out of the box. Just managed to scrounge another from my GoPro. Ill format that, reflash Raspbian and see how I go. I’ll just use your script first off, rather than doing a manual install. I’ll let you know how I get on, on here but it will take me a long time with all the updates that Raspbian does. Thanks so much for your help.

[sdetweil]

@mrlowndes ok, will be around…

[sdetweil]

someone else just reported a similar failure on a pi 0.

so, I reflashed my sd card with buster and ran the installer without any issues on a pi 0w
