ERROR: Could not build wheels for llama-cpp-python, hnswlib, lxml, which is required to install pyproject.toml-based project

[mkam0012]

I am trying to install the requirements on an Apple M1 Pro in a Macbook Pro and getting errors for building three wheels, have absolutely no idea how to fix

[mkam0012]

[Angurajdin]

I'm also facing the face issue ( I tried with Ubuntu and Cent OS - both failed with the same error),

[jackfood]

download and install the "Microsoft C++ Build Tools" from the official Visual Studio website. Here are the steps you can take:

Visit the following URL: https://visualstudio.microsoft.com/visual-cpp-build-tools/.

On the webpage, you should see a "Download" button for the Visual Studio Build Tools. Click on it to initiate the download.

Once the download is complete, run the installer and follow the instructions to install the Microsoft C++ Build Tools.

During the installation process, make sure to select the necessary components for C++ development. This typically includes selecting the "C++ build tools" and any required packages or libraries.

After the installation is complete, try installing the hnswlib package again using pip.

[zhaolong1990ok]

I'm also facing the face issue ( I tried with CentOS 7.6 - both failed with the same error)

[jackfood]

Also if using Llama GGLM, if langchain required, use 'pip install langchain[all]' to install all modules.

[abdulfarhandevil]

i installed Microsoft C++ Build Tools with "C++ build tools" as u mentioned but still getting this error

[Angurajdin]

Thanks @jackfood,I was able to install it on Windows (after using the Microsoft C++ Build Tools), but how do I do the same on Linux (Ubuntu, CentOS, or any other Linux environment) since we can not use the Microsoft C++ Build Tools in Linux?

[Angurajdin]

@abdulfarhandevil, Please share a screenshot of the Microsoft C++ Build Tools components that you installed

[abdulfarhandevil]

The red marked are the Microsoft C++ Build Tools components that i have installed
@Angurajdin Can u pls check if i missed anything or if its correct what should i do further to fix this issue

[taran11313]

@abdulfarhandevil
you can download the build tools from here - https://visualstudio.microsoft.com/visual-cpp-build-tools/

[taran11313]

I have found the solution for this problem -

1. First install visual cpp build tools from this link - https://visualstudio.microsoft.com/visual-cpp-build-tools/
2. Then install cython using the below command -
   py -m pip install cython
3. Set the following path in your PATH variable -
   C:\Users\XXXXX\AppData\Local\Programs\Python\Python311\Scripts

[ppcmaverick]

Its not working, it says cannot build wheels for hnswlib. I tried with adding the build tools and every damn thing. Is there a real step by step for this. I have already tried 3 times now.

[ppcmaverick]

Where to setup the Path Variable?

[jackfood]

@ppcmaverick

To set up Python in the PATH environment variable,

1. Determine the Python installation directory:

   • If you are using the Python installed from python.org, the default installation location on Windows is typically C:\PythonXX (XX represents the version number).
   • If you are using Anaconda or Miniconda, the installation location is usually C:\Users\YourUsername\Anaconda3 or C:\Users\YourUsername\Miniconda3, respectively.

2. Open the Control Panel:

   • Press the Windows key on your keyboard.
   • Type "Control Panel" and select it from the search results.

3. Go to System and Security:

   • In the Control Panel, click on "System and Security."

4. Click on "System":

   • Under the "System" section, click on "System" to open the system properties.

5. Click on "Advanced system settings":

   • On the left-hand side of the "System" window, click on "Advanced system settings" to open the System Properties dialog box.

6. Click on "Environment Variables":

   • In the System Properties dialog box, click on the "Environment Variables" button.

7. Edit the PATH variable:

   • In the "Environment Variables" dialog box, locate the "Path" variable under the "System variables" section and select it.
   • Click on the "Edit" button to modify the PATH variable.

8. Add Python to the PATH:

   • In the "Edit Environment Variable" dialog box, click on the "New" button.
   • Enter the path to the Python installation directory (step 1) by adding the following entry:
     • For Python from python.org: C:\PythonXX (replace XX with the version number).
     • For Anaconda or Miniconda: C:\Users\YourUsername\Anaconda3 or C:\Users\YourUsername\Miniconda3, respectively.
   • Click "OK" to save the changes.

9. Close the dialog boxes:

   • Close all the dialog boxes by clicking "OK" or "Apply" until you return to the Control Panel.

10. Open a new command prompt:

    • Open a new command prompt or PowerShell window to verify that Python is correctly set up in the PATH.
    • Type python or python --version and press Enter.
    • If Python is set up correctly, you should see the Python version information printed on the screen without any errors.

I tried upgrading and installing wheel, langchain dependencies, c++ compilers. But still I still got the same error(s) using Ubuntu 22.04. A Docker image would be nice for this.

[Keith-Albright-Bose]

https://visualstudio.microsoft.com/visual-cpp-build-tools/

Just to be clear, this downloads a windows exe which is not for M1 Mac.
Mac has clang.

On Mac, you will need the Command Line Tools for XCode (match your version and download from your developer login (developer.apple.com/download)
The hint was seeing this error in output BEFORE the Failed to build llama-cpp-python hnswlib lxml

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

After installing, open new terminal window, change to the directory where you cloned the repo and rerun
pip3 install -r requirements.txt

[albertas]

I was getting the same issue with Python3.10.x versions. However, I managed to solve them by upgrading to Python3.11.3.

All dependencies were installed successfully for Python3.11.3. I have used pyenv to install custom Python versions.

[qikongwanli]

I'm also facing the face issue ( I tried with Ubuntu and Cent OS - both failed with the same error),

Hi, I have successfully installed this project in WSL2 (ubuntu 22.04).
In order to install all requirements, I run these codes:
$sudo apt update
$sudo apt install g++ gdb make ninja-build rsync zip
$pip3 install -r requirements.txt

[prezire]

Upgraded to latest gcc-11/g++-11, pip and python 3.11.3 via pyenv but still nothing works on Ubuntu 22.04.

[TianruiZhang]

For CentOS, you may find this useful: https://zhuanlan.zhihu.com/p/632202007, it's in Chinese though.

[aminlv]

The red marked are the Microsoft C++ Build Tools components that i have installed @Angurajdin Can u pls check if i missed anything or if its correct what should i do further to fix this issue

you also have to install cli 2 it use cli to compile it

[emreg00]

Had the same issue with Ubuntu 18.04.6 and I was able to make it work following the instructions to update gcc-11 and g++-11 on this post.

[Naniyaking]

centos7
update cmake to 3.2.5 and update gcc to 12.3
create soft link
ln -s /install_dir/bin /usr/bin/gcc
ln -s /usr/bin/gcc /usr/bin/cc

[HN026]

I'm facing the same issue, I'm trying to develop this on Linux Fedora, can anyone help?

[cassina]

I solved the error by doing this:

pip3 uninstall -y -r requirements.txt
pip3 install --upgrade setuptools wheel
pip3 install -r requirements.txt

[elseifer]

I solved the error by doing this:

pip3 uninstall -y -r requirements.txt
pip3 install --upgrade setuptools wheel
pip3 install -r requirements.txt

It works on my macos

[sanjana-sudo]

I solved the error by doing this:

pip3 uninstall -y -r requirements.txt
pip3 install --upgrade setuptools wheel
pip3 install -r requirements.txt

Tried this on ubuntu, still not working...
here's the output for ref

I solved the issue on my WSL shown below.

on WSL1 Centos7:

yum install centos-release-scl
yum install devtoolset-9-gcc-c++
scl enable devtoolset-9 bash
pip3 install -r requirements.txt

on WSL2 Ubuntu 22.04.2 LTS:

sudo apt-get install python3.10-dev
pip3 install -r requirements.txt

Tried it on Ubuntu 22.04.3 LTS. Still facing the same error:

Is there something crucial I'm missing? like gpu requirements?

[JiaYingLii]

This is all because of gcc/c++ version is too low.

I fixed by running as below

sudo apt update
sudo apt upgrade
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-11 g++-11
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-11 60 --slave /usr/bin/g++ g++ /usr/bin/g++-11

(Ubuntu 18.04)

And make sure your python version is 3.11+.
Reference: Install gcc in ubuntu

[jarciniegas20]

I also faced the same issue when trying to install "llama-cpp-python" on my Mac. Ultimately, what solved the issue was running xcode-select --install on my terminal. This should open up a separate installer window. This installs the Xcode Command Line Tools on a Mac, which include the compilers needed for c and c++. After installing it, I checked the g++ was working with g++ --version You should now see the version, and running pip install llama-cpp-python should work.

[rpuls]

Anyone that managed to fix this issue on windows 11?
I installed visual studio 2022 and the c++ build tools. restarted machine
Still get same error.

[prateekrana17]

I have managed to fix this issue on Windows 11.
1)Uninstall Visual Studio, C++ build tools, Virtual C++ Redist, Windows SDK etc. (basically all C++ related Micrsooft Components)
2) Restart the PC
3) Install C++ build tools using Visual Studio and select all C++ options
4) Then install cython using the below command -
py -m pip install cython
5) Set the following path in your PATH variable -
C:\Users\XXXXX\AppData\Local\Programs\Python\Python311\Scripts
6) pip3 install -r requirements.txt

I have already installed (and double checked) visual studio 2022, also
pip install torch==2.0.0+cu118 --index-url https://download.pytorch.org/whl/cu118
also
py -m pip install cython
also
MiniGW and gcc components.

WHAT am I missing here? I don't understand how people make youtube tutorials where they start with a clean environment, then just copy paste the commands and it all magically works. Every time I try some new app, there's something that fails or something that's missing. If someone is going to release a tool like PrivateGPT can you make an installer .bat that will setup a venv, check for things already installed, install what is needed, detect CUDA, and set that up too. Jesus Christ.

[Choppra]

I couldnt agree with you more. I pride myself on understanding dependencies and building with docker and python. This is a soup of randomness. Tons of quirks and poorly written documentation.

Is there any solution for this problem on Apple Silicon? I have tried updating the software, I have tried everything else mentioned in this thread, is there something I am missing or is there some bug?
