I came across some problem when I install couterparty client .
2014-04-03 20:33:46,125|ERROR: Command failed: 'C:\counterpartyd_build\env\Scripts\pip.exe install -r C:\counterpartyd_build\dist\reqs.txt
Who knows how to solve it?
The error means that PIP, which is the python packages installer has failed to install the dependencies listed in the reqs.txt file. Do you have a more complete error log? One thing you can try is removing python if an old version is installed.
