ERRNO 126, ELIFECYCLE, permission denied on RPI3

@lavolp3 Hi, sorry for the very late follow-up, I was very occupied last week.

I’ve cleared the micro sd card and started from scratch, reinstalling raspbian and MM without Sudo privilege or any type of permission restriction.

The bad news is that it still gave the same error message. The good news is that I might’ve found the reason behind the failure. It seems to not be able to download nor install chromedriver.js. This might be caused by me being in mainland China right now, and the “great firewall of China” has blocked the download.

Is there any other way to get the chromedriver.js files and manually put it into the MM folder?

Thank you very much for your time!

@someone123416 try this…

npm install --only=prod

as the chromedriver is only needed for testing… which u won’t be doing…

if you used the automated install script then you wouldn’t have these problems…

Thank you, Sam, for your reply!

MagicMirror installed successfully with the --only=prod command, the error code about chromedriver has disappeared.

However, I am still getting the same error message (errno 126) when trying to npm start the program, in fact, the exact same error message.

I am really curious about why I am getting a permission error, as I’ve installed it without any privileges.

@someone123416 did u erase the node_modules folder

cd ~/MagicMirror
rm -rf node_modules
npm install --only=prod

@sdetweil Hi Sam,

Thank you very much for your reply.

I’ve tried earasing the node_modules folder, but still no luck. Exact same error message.

@someone123416 back in your original post, you said
“I’ve hooked up my rpi directly to a display via hdmi n everything works fine”

It works on a real display, but doesn’t some other way?

So, r u doing this over vnc? Or?

@sdetweil Hi,

Yes, it is hooked up to a real 24in display over HDMI.

I am not running this over vnc.

@someone123416 I guess I would delete the ~/.npm folder.

Then use my script to install mm
See https://github.com/sdetweil/MagicMirror_scripts

Have to rename/delete the existing MagicMirror folder
