ERROR: failed to run: pkg-config when running npm install git+https://git@github.com/danschultzer/receipt-scanner.git #62

Open Anima-t3d opened 5 years ago

When I run npm install git+https://git@github.com/danschultzer/receipt-scanner.git I get the following error:

I tried re-installing and also https://stackoverflow.com/a/46743865/3163075 to no avail.

Schultzer commented 5 years ago

What version of OpenCV do you have installed?

Anima-t3d commented 5 years ago

How can I check? I think I saw something like 4.0.1 when I was running the install.

Schultzer commented 5 years ago

The issue is in node-opencv

https://github.com/peterbraden/node-opencv/blob/db093cb2ec422e507a61e79dd490126060a7e7d0/utils/find-opencv.js#L18

var opencv = process.env.PKG_CONFIG_OPENCV3 === "1" ? "opencv3" : ' "opencv >= 2.3.1"';

The reason it errors is that you are using opencv 4. node-opencv has not been updated to opencv 4. You could try uninstall opencv 4 and install opencv 3 instead.

Anima-t3d commented 5 years ago

I ran brew uninstall opencv and brew install opencv@3, got a lot of warnings but it went through.

When I try to run the receipt-scanner I get the following issue:

Seems like it's no longer supported in tesseract 4 and now uses --psm

I tried brew uninstall tesseract and brew install tesseract@3 but couldn't find such version to install.

Schultzer commented 5 years ago

Yeah looking at https://github.com/desmondmorris/node-tesseract it doesn't support tesseract 4 yet.

Anima-t3d commented 5 years ago

@Schultzer Seems like node-tesseract is no longer maintained, there are a few pull requests addressing this issue already: https://github.com/desmondmorris/node-tesseract/pull/62

Anima-t3d commented 5 years ago

I applied the update as seen in desmondmorris/node-tesseract#62 in my local node_module, however I got the following error:

Seems related to #61
