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 installing 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.
