Bug Description

I tried installing langflow using the command pip install langflow on linux, and windows but its taking a very long time and then crashing

Reproduction

pip install langflow. for most of the packages I get below message .

INFO: This is taking longer than usual. You might need to provide the dependency resolver with stricter constraints to reduce runtime. See https://pip.pypa.io/warnings/backtracking for guidance. If you want to abort this run, press Ctrl + C.

Expected behavior

. Collecting langchain-community>=0.3.1 (from langchain-astradb~=0.5.2->langflow) Using cached langchain_community-0.3.3-py3-none-any.whl.metadata (2.8 kB) Using cached langchain_community-0.3.2-py3-none-any.whl.metadata (2.8 kB) INFO: This is taking longer than usual. You might need to provide the dependency resolver with stricter constraints to reduce runtime. See https://pip.pypa.io/warnings/backtracking for guidance. If you want to abort this run, press Ctrl + C.

Hey there, @researchase! I'm here to help you with any bugs, questions, or contributions you have regarding langflow. Let's get to the bottom of this together!

I found a similar open issue where the pip install command for langflow never finishes and gets stuck, particularly on httpx related packages. Here are some suggested solutions that might help:

  1. Upgrade pip: Make sure you have the latest version of pip.

    python -m pip install --upgrade pip

  2. Use a different index server: Sometimes the default PyPI server might be slow. Try using a different mirror.

    python -m pip install langflow -U --index-url https://pypi.org/simple

  3. Install httpx separately: Manually install the httpx package before installing langflow.

    python -m pip install httpx
python -m pip install langflow -U

  4. Use pipx: If issues persist, try using pipx to install langflow.

    pipx install langflow --python python3.10 --fetch-missing-python

If the problem continues, you might want to refer to the Possible Installation Issues section in the Langflow documentation for more troubleshooting steps [1].

To continue talking to Dosu, mention @dosu.

same here trying to resolve the dependencies. This should be solved by tightening up the dependency mapping.

Workaround pip install langflow --use-deprecated=legacy-resolver
