今天装环境的时候conda提示：

Solving environment: failed CondaUpgradeError: This environment has previously been operated on by a conda version that's newer than the conda currently being used.

最新的anaconda安装包是2018年发布的，自带的conda版本是4.5.11，很明显版本有点低，所以我们需要手动升级，打开下面这个网站：https://anaconda.org/anaconda/conda/files?version=4.5.13
选择对应的系统下载好conda的包，比如：linux-64/conda-4.5.13-py37_0.tar.bz2这个，下载完毕之后，进入base环境中，输入：
conda install conda-4.5.13-py37_0.tar.bz2

这样就成功升级conda版本，不过这个时候仍会报错，最后运行一下：conda config --set allow_conda_downgrades true
之后就可以正常安装了。
