错误conda.core.link:_execute(502）：安装软件包时发生错误

Question

尝试使用conda命令安装某些软件包时出错。我正在使用Ubuntu 18.04，并尝试在新的conda环境上安装[EQcorrscan][1]。重现步骤：

打开终端

conda install colorama numpy scipy matplotlib obspy bottleneck pyproj

收到错误消息：

Preparing transaction: done
Verifying transaction: done
Executing transaction: failed
ERROR conda.core.link:_execute(502): An error occurred while installing package 'conda-forge::colorama-0.4.3-py_0'.
FileNotFoundError(2, "No such file or directory: '/home/yongki/anaconda3/envs/obspy3/bin/python3.6'")

在互联网上寻找解决方案，仍然没有答案。
