cannot install pm2

[mrlowndes]

Hello. I’m getting this error when I try to install pm2:

• do I install in /MagicMirror directory?

pi@raspberrypi:~/MagicMirror $ sudo npm install -g pm2
npm ERR! Unexpected end of JSON input while parsing near '...s":{"moment-timezone"'

@mrlowndes not in MagicMirror…

did u try to install MagicMirror manually ?

do node -v and npm -v

what OS is this

show results of lsb_release -a

[mrlowndes]

@sdetweil yes, manual install of MM

pi@raspberrypi:~ $ node -v
v10.20.1
pi@raspberrypi:~ $ npm -v
6.14.4

how do I show results of lsb_release -a?

[sdetweil]

@mrlowndes lsb_release -a

same way you did results of npm -v

on my desktop i see

(base) sam@sams:~/MagicMirror$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.4 LTS
Release:	18.04
Codename:	bionic

do this

sudo apt-get purge -y npm 

then

rm -rf ~/MagicMirror

and then run my installer script from here
https://github.com/sdetweil/MagicMirror_scripts
read the readme for the command to issue

it will ask to install pm2 and disable screen saver

if you don’t, then I have extra scripts to do those

[mrlowndes]

@sdetweil ok I’ll give that a go. In the meantime:

pi@raspberrypi:~ $ sudo npm install -g pm2
npm ERR! Unexpected end of JSON input while parsing near '...s":{"moment-timezone"'

npm ERR! A complete log of this run can be found in:

and

[sdetweil]

@mrlowndes so, I asked you to uninstall npm

sudo apt-get purge -y npm 

[mrlowndes]

@sdetweil yes, stand by…

[mrlowndes]

@sdetweil purged npm, now running your installer script…updating packages…I’m on a 2Mb/s internet connection…

@sdetweil

We're ready! Run pm2 start MagicMirror from the ~/MagicMirror directory to start your MagicMirror.
 
 
pi@raspberrypi:~ $ cd MagicMirror
pi@raspberrypi:~/MagicMirror $ pm2 start MagicMirror
bash: pm2: command not found
pi@raspberrypi:~/MagicMirror $
