我尝试使用命令bokeh将conda update bokeh更新到1.4.0，但是遇到 [WinError 126]找不到指定模块的问题，如下所示
(base) D:\Users\jng>conda update bokeh

[WinError 126] The specified module could not be found
这真是令人困惑，因为我想更新bokeh，但是为什么conda想要下载无关的软件包keras-base-2.2.4和h5py.-2.8.0（已经在我的conda库中安装了）？另外，消息 [WinError 126]找不到指定的模块是什么意思？有人可以帮我解决问题吗？谢谢
