Yes sir, I did. I use a mac and I am unable to realize how to install opencv4nodejs. Can you please refer on the how to doc, what's exactly need to be done to install it. |
|
How did you install appium? |
|
Try to read https://docs.npmjs.com/ to know more about npm and NodeJS packaging system |
|
@KazuCocoa, I used the command npm i -g opencv4nodejs quite many times and restarted the appium. I was getting the same error again and again. (error: opencv4nodejs module is required to use OpenCV features). |

If you handle appium with |

The same problem, does anyone fix it? |

In general, this is npm(and If you manage your project with $ npm list opencv4nodejs # no opencv4nodejs

macmini550:~ vkuhi$ npm list opencv4nodejs It is in the node_modules package, how can I get access to it from my java project? |
|
If the If your Java project manages appium by |
|
I do not have any package.json in my Java project. How does the appium will know where this package located? |
it depends on npm/node. Appium depends on them to resolve dependencies. |
|
@vkuhi Initially I ran appium desktop app. I later (after reading the suggestions from in here) realized that the appium I am running and opencv4nodejs i installed are not from the same package/node_modules. So the shutdown the appium desktop app and verfiied the version of global appium, which was 1.7.2. I upgraded it to 1.9. Now that both appium and opencv4nodejs come from same package or node_modules, starting the appium from there solved my issue. Thanks @KazuCocoa and @mykola-mokhnach for your prompt help :-) |
|
Ah... I see. Thanks. I only explained about appium which is CLI tool. In desktop's case, that has its own package info. so, it can not find global opencv4nodejs. I would link appium/appium-desktop#714 |
|
I have same issue, node can't find opencv, working with win 10, any help will be appriciate. Appium server: I have already installed the opencv through npm, mime must be a string I am mantion that I already use install opencv in various ways: And also tried mannually, the appium doctor keep saying: But I got indication that the opencv is installed success when install from npm, |
|
What result can you get with |
That's the output: I am using appium server from java code, I am not using appium gui client desktop. |
|
thanks. |
I enter there, But honestly I have no idea what to do according that post, |
|
One is building Appium code. Another is waiting for the PR's release in beta building Appium from code
Or just wait for the PR will release. |
didn't help, |
|
Nothing help so far.... |
|
Update: |
|
thanks. I guess node dependencies affected that... |
|
I have install opencv4nodejs by npm install -g opencv4nodejs. How should I install the opencv4nodejs and anything need to be configured? |
|
I could not find the solution for desktop appium/appium-desktop#714 You can run appium CLI separately and connect to it from the desktop app via the custom server tab in the inspector. |

@KazuCocoa , { Error: Command 'ffmpeg -version' exited with code null is FFMPEG is required by OpenCV4nodejs? or do we need tessract lib. ? (Becoz i've removed it for issue in opencv4nodejs installation) |

I guess your local environment refers to Latest Appium loads a npm package as https://github.com/appium/appium-support/blob/15afcad2329e872f76195120ff238450fafc3bbb/lib/node.js#L38-L64, so it calls e.g.

OpenCV is very difficult to install. I wish we didn't depend on it for these features. But we cannot support OpenCV & OpenCV4NodeJS installations. Once you have it set where opencv4nodejs can be required, then Appium will work with it. |
can. you advise me about other libraries to compare two images for same element ? |
The problem
I am trying to use appium image comparison and used the reference code
byte[] screenshot = Base64.encodeBase64(driver.getScreenshotAs(OutputType.BYTES));
OccurrenceMatchingResult result = driver
.findImageOccurrence(screenshot, partialImage, new OccurrenceMatchingOptions()
.withEnabledVisualization());
assertThat(result.getVisualization().length, is(greaterThan(0)));
assertNotNull(result.getRect());
I see the following error:

My project is in java and I am really not sure about performing npm i -g opencv4nodejs. Should I do npm i -g opencv4nodejs under the project root, though the project doest not have package.json
