so I recently upgraded to Python 3.9 and when trying to install some libraries - specifically pip install discord - I encountered the following error:

  ERROR: Command errored out with exit status 1:

Failed to build multidict yarl

Obviously I went to the link and downloaded the build tools and then checked the C++ part but after restarting my computer, re-installing visual studio, I am still encountering the same problem. I am wondering if there is a part in the installation process that I am missing out on or if I have messed something up. Any help appreciated.

Try to install Visual Studio: https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=16, and Visual Studio C++ Build Tools: https://visualstudio.microsoft.com/visual-cpp-build-tools/. The problem should be fixed.

Make sure you have version 14+.

  • Already have it installed, like I said, I've tried re-installing it multiple times. – cap Oct 31 '20 at 01:05

  1. Open up visual studio installer and select modify build tools
  2. Go to individual components and make sure C++ 2019 Redistributable Update, C++ CMake tools for Windows, MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.27), C++ AddressSanitizer (Experimental), C++ Build Tools core features, are checked.

If not check them and select modify. If you are on an ARM or ARM64 based system, replace MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.27) with the ARM or ARM64 version.

  • @cap, you only typed pip install discord? no arguments along with it? If so, then check where you have the C++ extensions installed, for me it is C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools – unbeatable101 Oct 31 '20 at 02:42
  • Is it a problem that in the Visual Studio Installer - build tools is called "Visual Studio Build Tools 2019 (2)"? I would think that the "(2)" in the title may be causing some issues. – cap Oct 31 '20 at 02:43
  • @cap Could you upload a picture to imgur and link it here? – unbeatable101 Oct 31 '20 at 02:46
  • a picture of what? Also how could I go about finding where the C++ Extensions are installed? – cap Oct 31 '20 at 02:48
  • @cap https://imgur.com/4YkYyCg location is at the bottom of the manage section. An image of where it says Visual Studio Build Tools 2019 (2) I'm going yo bed now, I'll try to help you tmrw – unbeatable101 Oct 31 '20 at 03:20
  • They are at C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools. Also, here is the image of the name: https://imgur.com/a/f3Sj9Eu – cap Oct 31 '20 at 21:35

I think for installing discord api you need to write the command pip install discord.py and not pip install discord
