Pip install combocurve-api-v1 Issue

1

Hello,

I was able to install the combocurve api package for python on my machine a few months back, but for some reason it’s not working on my coworker’s computer.

We tried running pip install combocurve-api-v1 directly in jupyter lab and also in the anaconda prompt and pip is saying it’s likely an issue with the package. Getting the error below.

Could we get some help with this?

Thanks!

I have not come across this error before.

The error message seems to indicate that you are missing the required Microsoft Visual C++ Build Tools, specifically the vcvarsall.bat file, which is necessary to compile parts of the cffi package during the installation of the combocurve-api-v1 package.

See if installing Microsoft Visual C++ Build Tools Resolves the issue:

  • Download and install the latest version of Microsoft C++ Build Tools.
  • During the installation, ensure that you select the components for “Desktop development with C++”. This will include the necessary tools and libraries needed for compiling C++ code.

When I installed the package a few months ago, I did not have to download Microsoft C++ Build Tools. I don’t even have it installed on my machine. I simply just executed pip install combocurve-api-v1 in the Anaconda Prompt.

We got it to work this morning by doing as you suggested above. This stackoverflow post was helpful for walking through the installation process.
