Error building PyCall

[davidzentlermunro]

Tried to use PyPlot recently and was instructed to build PyCall, then received another error relating to Conda environment:

It says it fails to run C:\Users\uctpdtz.julia\conda\3\python.exe. Does running this work from a console?

Maybe the permissions on your C:\Users\uctpdtz.julia\conda\3 directory got messed up somehow?

I am having a similar issue. Instead of failing to create the process, the process exits in failure when trying to install miniconda.

Any help would be appreciated

ERROR: LoadError: failed process: Process(`/root/.julia/conda/3/installer.sh -b -f -p /root/.julia/conda/3`, ProcessExited(1)) [1]

[stevengj]

@pasta41, it sounds like your error is totally different. Please open an issue at Conda.jl if it recurs. (If it is a simple download failure, it might be a firewall blocking the installer.)

I'm closing this issue as the original problem does not seem reproducible.
