Fail to install activity browser (Windows x64) #74

Closed nejvas closed 1 year ago

nejvas commented 1 year ago

Dear all,

Following the instructions here (https://documentation.brightway.dev/en/legacy/source/setup/setup.html) to install brightway 2 for Windows x64 and the instructions here (https://github.com/LCA-ActivityBrowser/activity-browser#installation) to install the activity browser I never get past the command "conda create -n ab -c conda-forge activity-browser" (see below, username substituted by "xxx"). After getting the error message it seems it never stops "solving the environment", even if I wait for a longer time...

A friend has the same problem on his computer. Any ideas how we can address the problem? We tried both, working in the Anaconda Prompt and the Miniconda Prompt.

Many thanks!

Nejvas

Hey, @nejvas - thank you for filing the issue. Please note that the Activity Browser (AB) is a project that is mantained separately from Brightway. Brightway only provides the computational core for AB. If you experience issues with AB, please file an issue in their repo: https://github.com/LCA-ActivityBrowser/activity-browser#installation

However, having looked at the documentation that they provide (to which you linked), it seems that you don't need to install Brightway separately before installing AB. Instead, follow their installation instructions:

Install the AB with ecoinvent >=3.9

After prepending the Conda-Forge channel the following line should be executed within the command prompt/terminal to install the AB and it's dependencies.

conda create -n ab activity-browser

This will install the Activity Browser with the latest version of the Brightway2 libraries (currently excluding Brightway2.5 libraries).
