ImportError: DLL load failed: The specified module could not be found about rapidfuzz HOT 7 CLOSED

Thanks Max, I think I'll add a try/except clause in my code and have my documentation point to yours if the name prediction doesn't work.

Yes this did change. Until v0.8.0 the C++ implementation was placed in rapidfuzz._fuzz and was imported in rapidfuzz.fuzz. The reason for this was, that the C++ version did not support a processor and therefore inside rapidfuzz.fuzz it would simply preprocess the strings and then call the C++ version.
However since calling python functions is really slow I added support for the processor argument in v0.8.0 and removed the intermediate python function. So now rapidfuzz.fuzz is the C++ implementation and rapidfuzz._fuzz does no longer exist. The same was done with rapidfuzz.utils.

OK... but the from rapidfuzz._fuzz import * is not in my code... it must be somewhere in RapidFuzz? The only reference to rapidfuzz in my code is here:

The reason I was thinking PyPI is maybe you used to upload windows wheels? I'm really not well-versed in PyPI, but the DLL note is what trigged my comment. I just tried my project with rapidfuzz 0.9.1 on macOS with no issues. I asked my user for his version... unfortunately I personally won't have access to MSW until Thursday.

Ah reading the error again I am pretty sure I know what the problem is. It appears he is using a version where rapidfuzz._fuzz still existed, but Python is not able to find this. The reason for this is, that on Windows the C++ redistributable is required to find C++ libraries. I do not have a barebone Windows installation here, but as far as I remember Windows 10 only comes with the 2013 version, but since rapidfuzz is using C++14 it is using a more recent version. The more recent versions 2015, 2017 and 2019 are now all part of the 2019 version. https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

I added this to the new docs aswell https://maxbachmann.github.io/rapidfuzz/installation/, since others did already run into this aswell.

OK. This is starting to make sense. Although, I don't have C++ installed on my MSW7 computer at work. Again.. this is why I was learning toward wheels. Maybe there's just not a wheel for his environment?

@MohammadSalehi72 this comment above may help your rapidfuzz issue

When there is no wheel + he has no C++ compiler it would already fail to install and when he has a C++ compiler and it builds it for him, he would be able to find the dll. So I guess there was a wheel (there should always be one for Windows 10), but the C++ redistributable is used by a lot of programs, so it might very well be, that it was already installed on your system.

I am not super familar with Windows (mostly using Linux), so I did not find a way yet, to either install this for the user, or to throw him at least a warning, that he has to install the C++ redistributable, since the dll import error is not really user friendly.
