There was an issue executing GraphicsMagick/ImageMagick: the operation "identify" with the arguments "-ping" and "-format" "%wx%h" could not be completed

I am currently attempting to locate the measurements of the images on a production machine, but encountering errors.

An error occurred while trying to execute GraphicsMagick/ImageMagick: identify "-ping" "-format" "%wx%h" "uploads/userPhoto-1499669685192.png". This most likely indicates that the gm/convert binaries cannot be foundsize==undefined

Interestingly, this process operates smoothly on my local machine. Additionally, I have already uploaded modules on the production machine that match those on the local one.

Answer №1

As per the source code for gm, this issue occurs when the spawn (function used to launch a process) returns an ENOENT error, indicating that the required program was not found in the $PATH for the currently running node process (It could be present but you need to verify the environment of the running process).

Therefore, it seems to be a straightforward installation problem with the necessary components. While your local machine may have all the requirements installed, the production machine does not. Even though you mentioned that you "uploaded all modules" (presumably referring to npm modules), that alone is insufficient as the gm module depends on either GraphicsMagick or ImageMagick.

Quoting from the main page for gm:

First download and install GraphicsMagick or ImageMagick.

Answer №2

It seems that the installation of graphicsmagick or imagemagick may not have been completed properly. You can resolve this issue by downloading GraphicsMagick or ImageMagick. If you are using Ubuntu, the following commands can be helpful:

sudo add-apt-repository ppa:dhor/myway
sudo apt-get update
sudo apt-get install graphicsmagick
sudo apt-get install imagemagick

I have provided some examples below demonstrating the usefulness and simplicity of the identify command. For instance, to identify an image in JPEG format, use the command:

$ magick identify rose.jpg
> rose.jpg JPEG 70x46 70x46+0+0 8-bit sRGB 2.36KB 0.000u 0:00.000

If you want to determine the print size of an image at 72 DPI in inches, run:

$ magick identify -format "%[fx:w/72] by %[fx:h/72] inches" document.png
> 8.5 x 11 inches

You can explore more options and detailed information about the identify command from this link.

Answer №3

Although this information may be outdated, I encountered no issues in Fedora. However, when using Travis CI on Ubuntu:

The following command does not function properly

 sudo apt-get -y install imagemagick

Instead, the following command works as expected:

 sudo apt-get -y install graphicsmagick

Answer №4

Here is what worked for me:

  1. To start, open the command prompt as an administrator, navigate to your project folder, and type "grunt" into the command prompt.
  2. If you encounter an error indicating that "grunt hasn't been installed locally to your project," ensure that both grunt and grunt-cli are properly installed.

If you are using Windows and continue to experience issues, try reinstalling via ImageMagick.exe:

  1. Begin by visiting and downloading the exe file.
  2. Run the downloaded file on your local machine.
  3. During installation, be sure to select "Install legacy utilities (e.g. convert) on 'Select Additional Tasks' option."
  4. Once the installation process is finished, type "grunt" from your project directory in the command prompt.

Answer №5

After installing ImageMagick, it is important to create a symbolic link to gm in a publicly accessible directory such as /usr/local/bin on Mac using the magick binary. Running this command can be beneficial.

ln -s /path/to/bin/magick /path/to/bin/gm

The gm should be positioned in an accessible path for the terminal to recognize.
