Python 安装bokeh时出现问题：[WinError 126]找不到指定的模块,python,installation,anaconda,Python,Installation,Anaconda,由于无法更新bokeh版本0.12.7，我使用conda remove-bokeh删除了该包。然后，我用conda安装-c bokeh-bokeh-bokeh安装了新的bokeh版本1.0.4。但是，我收到错误消息[WinError 126]无法找到指定的模块。奇怪的是我能看到这些文件夹和文件 bokeh-1.0.4-py37_0，packaging-19.0-py37_0， yaml-0.1.7-hc54c509_2，bokeh-1.0.4-py37_0.tar， packaging-19.

如果从默认设置而不是从
bokeh
频道安装，会发生什么？如果您创建一个新的单独的conda环境而不是安装到base中，会怎么样？您也可以尝试更新conda本身。@bigreddot，我确实将conda更新到了4.8.2。请详细说明从默认值安装是什么意思？认为我已经破坏了我的conda环境（通过删除bokeh 0.12.7），我尝试使用
conda安装--version 20
恢复到以前的版本，但得到了一个值错误：太多的值无法解包（预期为2）。然后我运行了这个命令
conda install bokeh
，不料它确实安装了bokeh（但只安装了版本0.12.7）。然后我运行了
conda update bokeh
，但收到了10个可能的包解析的警告，并且WinError 126]无法找到指定的模块，无法从默认设置安装，请不要添加您拥有的
-c bokeh
。它指定anaconda.org上的“bokeh”频道，而不是主默认频道。在任何情况下，这些都是康达的问题，看起来你的环境可能被破坏了。Anaconda的优点之一是它在一个用户目录中是自包含的。我会把一切都吹走，重新开始。在将来，使用conda环境而不是安装到base中（那么您只需要删除/重新创建一个环境，而不是整个安装），谢谢，@bigreddot。使用单一环境进行高效删除/重新创建的好主意。
