Is it happening for all the images or for a specific image only? If it's the later, can you please upload the image?

Answer 2 · 2016-11-25T04:42:21.000Z

Did you install the perquisite?

$ sudo apt-get install graphicsmagick # Ubuntu
$ brew install graphicsmagick         # Mac OS X

Shouldn't the lwip fallback prevent this?

Answer 4 · 2017-06-04T09:12:34.000Z

@m59peacemaker It should the lwip fallback should prevent the spawn error (ENOENT command not found ..., or so). It's very hard to tell why does this problem appear at all, because we have no example when it fails like that.

The OP seems to have GraphicsMagick already installed.

Did it happen to you as well?

Answer 5 · 2017-06-04T12:00:58.000Z

I did originally get the same error as the OP. I'm not sure whether I had graphicsmagick installed, but I thought I didn't and so went ahead installed it without checking first (oops). The same error remained. I just purged graphicsmagick and reinstalled image-to-ascii globally, now the error is simply error spawn gm ENOENT. I was just checking out the package. I don't have a stake in getting it working, but I hope my notes help.

@m59peacemaker Thanks for that! I will look into that error when getting a little bit of time. Sounds like lwip is not used...

Answer 7 · 2017-06-08T06:56:05.000Z

I reproduced this error on my machine. I'm on it.

Answer 8 · 2017-06-08T17:31:31.000Z

@m59peacemaker @abdennour For my information—did you receive any errors during the installation?

You can double-check by running rm -rf node_mdoules && npm install

Answer 9 · 2017-06-12T05:58:48.000Z

The installation should fail if lwip fails to be installed.

Addressed in IonicaBizau/lwip2#16.

The reason for the error was: in case gm is not available, lwip is installed (and compiled). In case the required tools for compilation are missing (e.g. XCode or so), lwip installation was failing silently. Now that error should block the image-to-ascii installation. 💥
