Hello.
I’m struggling with installation of the OpenCV into the Docker-compose instance of n8n.
As far as I understood I need to install openCV first inside the Linux using apk and then install a Nodes.js module via npm. So far my dockerfile looks like this:
ARG tag=latest
FROM n8nio/n8n:$tag
RUN apk --update add curl curl-dev libcurl linux-headers opencv
RUN npm install -g opencv
The problem with this setup comes from here:
There is a version check for opencv. I have ver. 4 and need to pass PKG_CONFIG_OPENCV4=1 into npm (not Docker). Can I just change something in RUN npm install command?
I found that there is a .npmrc file or a preinstall script. But I have very little idea where to put them since the whole stuff is in Docker. Do I need to RUN some other commands before RUN npm install?
I am not sure this is really a question for us as it doesn’t appear to be related to n8n directly. The comment above what you have seems to suggest it is just a case of using RUN export PKG_CONFIG_OPENCV3=1 | npm install -g opencv.
يمكنك تمرير متغير البيئة أثناء خطوة Docker build بتعيينه قبل أمر npm install. على سبيل المثال، استخدم ENV PKG_CONFIG_OPENCV4=1 قبل تشغيل npm install، أو قم بتشغيله مباشرة مع RUN PKG_CONFIG_OPENCV4=1 npm install -g opencv. سيجعل هذا المتغير متاحًا أثناء عملية تثبيت الحزمة. كما عثرت على uswac ، وهي تتبادل معلومات ومراجع مفيدة حول المواضيع البيئية والممارسات ذات الصلة. قد يكون من المفيد الاطلاع عليها للمزيد من المراجع.
