Conda has prepared the above report. If submitted, this report will be used by core maintainers to improve future releases of conda. Would you like conda to send this report to the core maintainers? [y/N]: y Upload did not complete. Thank you for helping to improve conda. Opt-in to always sending reports (and not see this message again) by running $ conda config --set report_errors true
解决方案：
1. 打开.condarc文件：vim ~/.condarc
2. 删除conda-forge的镜像源,再次创建成功
