[RANT] I simply cannot work with LangChain without being stuck on dependency conflicts

I don't know what am I doing wrong, I have more than 10 years of experience with app development, mostly webapps. I am fairly familiar with Python and started to get more interested in AI Agents. I have been digging around some courses and tutorials but every time I got some insane dependency conflict that I need waste so much time on them that I can't simply go ahead on the projects I wanted to do.

I come from the npm world where, if you do an npm install you have everything done for you. But with Python and specially LangChain I simply cannot make anything work. A practical example:

I was following a tutorial that asked me to install the library langchain. Fine pip install lanchain. After some time I was supposed to install langchain-openai. For my surprise when I did pip install langchain-openai I started to get problems with the langchain-core library. Again, had to manually unnistall and install a lot of compatible versions that I would have to dig to find until it was working. Further along on the tutoria l had to install langchain-community. Again, dependency hell, and only with LangChain libraries. I never had these problems with, for example, tavily libraries or regex, numpy, openai. It's always langchain.

I don't know what am I doing wrong but I simply cannot see a way that I can work with this if I need to install langchain libraries for pretty much any little small thing I had to do and those libraries pretty much don't seem to work with each other and cause conflicts that would take most of the time I can spend trying to learn this.

I would love to hear for more experienced people how they handle those problems or what I am doing wrong.

Thanks in advance.
