Building wheel for multidict (pyproject.toml) ... error

Answered

Hi there,

I am following the tutorial to build my first demo bot using the symphony-bdk-python .
When I get to the step : \BotProject>pip3 install -r requirements.txt
The installation process runs into the below error:

Building wheel for multidict (pyproject.toml) ... error
error: subprocess-exited-with-error

× Building wheel for multidict (pyproject.toml) did not run successfully.
│ exit code: 1
╰─> [59 lines of output]
*********************
* Accelerated build *

file

Then the below error:

 running build_ext
  building 'multidict._multidict' extension
  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/
  [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for multidict
Building wheel for yarl (pyproject.toml) ... error
error: subprocess-exited-with-error

× Building wheel for yarl (pyproject.toml) did not run successfully.
│ exit code: 1
╰─> [37 lines of output]

An as a result  symphony-bdk-python is not installed.

Can you please point me to a possible solution.

I am using Python 3.11 in Visual Studio

Thanks

Hi Vinay,

Many thanks for your reply . I did all the above but still not working for me.
I updated pip and "Microsoft C++ Build Tools"
I believe the modules in the requirements cannot be sucessfully installed using Python 3.11
It seems like python 3.8 can allow sucessful installation.
However, because the virtual envenronment (env) is automatically created by the bot Generator as below using python 3.11
file
Any attempt to install the modules in the requirements file will fail because the Python version in the generated virtual environment is not pyhton 3.8

Can you please try the installation using python 3.11 and see if it works.
If not could you please provide a possible workaround.

A side question is: how do you stop a bot that is running?

Many thanks for your help.

ERROR: Failed building wheel for multidict

depends on your operating system, wanted to point out i was on Linux,

I had a problem with multidicts, same basic error but for a different application - i found your post and wanted to add this incase anyone else stumbles upon it and finds some relevance for any time spent.

using this command worked for me and i was able to run the command again with success.

fixed it

sudo dnf install python3-devel

or fixed it

 sudo apt-get install python3-devel

hope it helped
