Windows 10 amd64, Python 3.7.4, Conan 1.18.4 from pip within virtualenv

I am working within conan-libpq-stable-11.4 directory, which is extracted libpq/11.4 from https://github.com/bincrafters/conan-libpq.

My env:

>echo %CONAN%
C:\Users\Vincas\code\cpp\branches\upgrade\\3rdparty\Conan\_python_3.7.4_venv_conan_1.18.4\Scripts\conan.exe

>%CONAN% --version
Conan version 1.18.4

I have conan_profile_windows.txt like this (for building libpq on Windows using CMake):

include(default)
[build_requires]
cmake_installer/3.15.3@conan/stable

I run development flow commands:

>%CONAN% source . -sf src

>%CONAN% install . -if install -s "compiler=Visual Studio" -s compiler.version=14 -s arch=x86 -s arch_build=x86 --build=missing -p conan_profile_windows.txt

But since I’ve added conan_installer as build depends, I get this output:

>%CONAN% install . -if install -s "compiler=Visual Studio" -s compiler.version=14 -s arch=x86 -s arch_build=x86 --build=missing -p conan_profile_windows.txt

I assume it should work without accounts for fetching recipes…?

Conan 1.18.5 has been released limiting urllib3 < 1.25.4

[lasote]

I’ve found the cause: https://github.com/urllib3/urllib3/blob/master/CHANGES.rst#1254-2019-09-19 Something has changed in urllib3 (transitive requirement of requests) at version 1.25.4 released on Thursday, if I upgrade my local installation I reproduce the error. ~We will keep investigating and opening an issue to urllib3~ See here but in the meantime, run:

• pip install urllib3==1.25.3 after your pip install conan
• We are going to release a Conan 1.18.5 fixing the transitive requirement.
