how can i fix this error any help will be appreciated

Answer 1

solved the problem by manually downloading the appropriate .whl file (Python version and Windows architecture), download ecos in whl format here . Navigated to the downloaded file (in terminal) and ran:

pip install ecos-2.0.7.post1-cp37-cp37m-win_amd64.whl 

Answer 2

I want to start by stating that the packages that come on Anaconda channels are already built, so the build step is not required (maybe [SO]: Installing pygraphviz on Windows 10 64-bit, Python 3.6 might be useful). In this case:

• _ecos.cp37-win_amd64.pyd is in the ECoS archive (to support my statement)
• On the other hand, CVXPy was not found (maybe I don't have the right channel set), so maybe that's why you weren't able to install it

The fact that this is a dupe of [SO]: Failed building wheel for fancy impute using pip install (as indicated in the comments) is debatable, depending on what one considers to be the question:

1. The effect: a ( C ) compile error preventing the .whl to build (and thus to install)
2. The root cause: the nature on the compile error at #1.

Those who opt for #1. , will see this question as a duplicate, while those who opt for #2. , won't. As a side note, I consider myself part of the latter category.

Regardless of anyone's choice (from the 2 options above), downloading the .whl from [UCI.LFD]: Unofficial Windows Binaries for Python Extension Packages and pip install ing it, would get past the ( this ) problem .

Since I'm on the 2 ^nd category, I investigated a bit more. On the other question, the error ( undeclared identifier ) is in (an older version of) the ECoS code, while here both CVXPy and ECoS fail to build, because some (standard) header files are not found:

• corecrt.h
• io.h

These both are part of UCRT ( Windows SDK ). For more details, check [SO]: How to circumvent Windows Universal CRT headers dependency on vcruntime.h (@CristiFati's answer) .

Since you don't have the 2 files (and most likely many others), your VStudio 2017 ( Enterprise ) installation seems to be corrupt (or incomplete - if this even makes sense).

Try repairing your VStudio installation, and while you're in the installer, make sure you have (at least) one Windows 10 SDK component selected:

Note, that you might need to restart the machine (in some rare cases) for the changes to take effect. If it doesn't fix the problem, you could consider reinstalling VStudio .

On my end ( VStudio 2017 Community ) everything went smoothly (apparently, I already had (the right) CVXPy installed):

As a conclusion, the error in the question is just the manifestation of another (deeper) one, which would definitely "show its teeth" on other scenarios as well.
