cl.exe failed with exit code 2 during installation #3

Closed Nicolas-Schlegel closed 12 months ago

Nicolas-Schlegel commented 1 year ago

Hello, when running pip install pylanczos, I get the following error message : 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2022\\BuildTools\\VC\\Tools\\MSVC\\14.38.33130\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2

I am using python 3.9.13. Do I need to have lambda-lanczos installed for pylanczos ?

Thank you for informing about the problem. This was a C++ version compatibility problem on MSVC (you don't have to install lambda-lanczos separatly).

I've just fixed the problem and released new version pylanczos==2.1.1. Could you try pip install again?

@Nicolas-Schlegel I've added a CI build on Windows and confirmed the build works properly. So I close this issue.
