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.

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:

Upgrade pip: Make sure you have the latest version of pip.
```
python -m pip install --upgrade pip
```
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
```
Install httpx separately: Manually install the httpx package before installing langflow.
```
python -m pip install httpx
python -m pip install langflow -U
```

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 issue

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

Nov 29 '24 01:11 rupjae

the workaround works for me

Nov 30 '24 16:11 dsolito

this work around builds, but I'm getting issues with the beta features. like connecting postgres as an sql database. [12/01/24 15:44:10] ERROR 2024-12-01 15:44:10 - ERROR - glogging - Worker (pid:****) was sent SIGSEGV!

should we only expect the legacy feature to work with this workaround? and plans to have a permanent fix of this to use the beta feautres?

This requirements.txt from @abdulqader999 was great! Thanks for sharing. After unsuccessfully trying all prior workarounds, I used these requirements and was able to build successfully. Python 3.12

Dec 02 '24 07:12 jkosgei

error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

The workaround moved further than ever before my trials, but I got an error message above. Python 3.12

My laptop is Windows and I tried above requirements.txt with Python 3.10, I have some extra issues but finally managed to have it local:

Got this error related to milvus-lite. ERROR: Could not find a version that satisfies the requirement milvus-lite==2.4.10 (from versions: none) which is discussed also here: https://github.com/milvus-io/milvus-lite/issues/90 saying that the version is not supporting Windows anymore, either you need docker to utilize it.

Got this error too: RuntimeError: uvloop does not support Windows at the moment

Got this error: error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

Got this error: × Building wheel for llama-cpp-python (pyproject.toml) did not run successfully.

Solution: Removing dependencies creating issues & no-need: Meanwhile, I also reinstalled my C++ with the Visual Code Installer. As recommended here: https://visualstudio.microsoft.com/visual-cpp-build-tools/

can you try python 3.10 I had issues with 3.11 and 3.12 as well

can you try python 3.10 I had issues with 3.11 and 3.12 as well

Yeah I tried three of them but had no luck, until I update and reinstall my C++ for CMake. After I installed recommended setup per Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools"

Hi, I am sharing my solution to this issue here, I'm also using Python 3.12.7 with Fedora. While I encountered the same issues others described, I was able to solve them by installing langflow with uv, First, I have installed uv with: (Linux/Mac) curl -LsSf https://astral.sh/uv/install.sh | sh For Windows: install uv on Windows

Then, I already have an activated environment (with PIP) so I just used uv's pip intefrace i.e. uv pip install langflow

After few seconds (literally) I get langflow up and runing with : langflow run

With pip, it take a lot of time, then it will fail. Hope this helps.

Dec 04 '24 09:12 hannody

@hannody uv is blazingly fast compared to installing the same via pip

Dec 18 '24 00:12 yasir-khalid

langflow installation on Windows stuck or slow with "pip install"?! Solution: using "uv pip install" method is way faster and recommended. Step to implement: 1- ctrl +C to abort the process. 2- Install uv with pip. " pip install uv". 3- run "uv pip install langflow" 4- run " langflow run".

Dec 19 '24 18:12 zcodehub

I've had the same issue all listed above, however, what worked for me was installing first uv:

pip install uv

and then:

uv pip install langflow

Dec 19 '24 23:12 MoonHawlk

Using UV was the solution! thank you all for your help!

Dec 29 '24 02:12 GnomiesDraenai

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

How to install the dependencies, Does the workaround command install the dependencies automatically?

Jan 20 '25 23:01 balrajvishnu

If you just want to have a try in windows and don't want to install the Visual C++ compiler. Install everything in sandbox to avoid the creation of AppData\Local\langflow:

Install Python 3.11 (most whl availability). Install Git if needed.
pip install uv
uv venv --python 3.11 langflow311_uv
uv pip install webrtcvad-wheels
uv pip install --only-binary webrtcvad langflow
uv run langflow run

Apr 18 '25 07:04 mimi3421

Thanks for the reply. I now program the models directly, so more need for langflow.

Hello. perhaps someone has this problem too. I'm on Python 3.11 due to some incompatibilities with configparser from some lib, I was on Python 3.13, at least trying to. But well, on Python 3.11, here is my full setup, I'll divide it into original file with requirements and final file with all dependencies (107 original vs 547 libs final)

Don't worry on the version numbers, if you're on a clean enviroment it won't cause issues with one another. The version numbers were resolved by UV, surprisingly and absurdly fast - 21 seconds to install and resolve everything I guess the half and hour time to install these libs are a thing of the past now.

My env is tailored for azure, although some many google libs were installed aftewards. Here's the files guys:

Command used:

uv pip install -r "<file path>.txt"

pipx didnt work on installing langchain or langgraph, in fact it recommended me to use pip instead hahah. So I went to UV and was not disapointted. Python 3.11 is a rather stable version yet so I guess this could help someone as it is still used.

If I solve the issues with Python 3.13 I'll try to install everything on there too. It seemed incompatible libs in essence, so no support yet to have a full 3.13 with everything installed.

This solution worked for me. I'm using the httpx

´´´ FROM python:3.10-slim

RUN apt-get update && apt-get install -y
build-essential
gcc
libmariadb-dev

&& rm -rf /var/lib/apt/lists/*

RUN pip install --upgrade pip
&& pip install httpx RUN pip install --no-cache-dir
