【问题描述】：
我使用的是Python 3.6.3，它是使用Anaconda安装的。
我已在命令提示符处运行以下命令来安装 Seaborn。
我在安装过程结束时收到以下错误消息：CondaError: Cannot link a source that does not exist.
我还包括以下整个安装消息：

我还没有运行conda clean --packages（如上所述），因为担心我可能会把事情搞砸。
当我运行pip show seaborn 时，它给了我Seaborn version 0.8（目前，Seaborn 是 0.11.0 版）。
安装失败了吗？下一步应该是什么？以及如何获得Seaborn 0.11.0？

1.这不是问题，只需按照建议运行
conda clean --packages即可清理包缓存。 2.可以肯定的是，首先通过运行conda install tqdm安装tqdm
