Can not use conan to get boost library because of the conanfile.py of boost.

[fancygit]

Hi @fancygit - Presumably it's this following line in the Boost conanfile.py: https://github.com/conan-io/conan-center-index/blob/master/recipes/boost/all/conanfile.py#L2

I have tried to reproduce this on Conan 1.48.0, but I get no issues running:

from conan.tools.files import rename, rmdir, get

The error is coming from a version of Conan installed within a Conda environment: Is it at all possible that the version of Conan that is installed inside the Conda environment is different than 1.48 You can run conda list within the activated environment to get the list and versions of packaged installed, or conda list -n dev (assuming your environment is called dev).

Thx @jcar87 I've tried 2 ways to install conan.

1. 2.

The version of Conan installed by Anaconda is After update conan from 1.46.2 to 1.51.0, it works!

And The version of Conan installed by binary redistribution is 1.48.1. About 2 weeks ago, it works well. But yesterday when I cleared all the downloaded library of Conan and tried to re-download all the library that I needed. Most of them can be well handled except Boost.

The following is the output: Running C:\Qt\Tools\CMake_64\bin\cmake.exe -S D:/Projects/QtCreator/TxToolBox -B D:/Projects/QtCreator/TxToolBox/build/Debug in D:\Projects\QtCreator\TxToolBox\build\Debug. -- Qt Creator: conan package manager auto-setup.

I hope that I've described my problem clearly.

Hi @fancygit - thanks for confirming your version of Conan and updated to a more recent version.

Would you mind trying again? There was an issue with a recent update to the Boost recipe in Conan Center that we have fixed recently.

However, I can see in the logs you have posted that the version reported is 1.48.1 - which may not be recent enough for some of the latest changes in Conan Center. Any chance of locating where that one is coming from?

-- Conan: Version found Conan version 1.48.1

I guess this was solved by updating the Conan version and the package recipe from boost, so closing as solved. Please create new tickets if necessary, thanks!
