Python:已成功安装模块，但无法通过导入使用

我正在使用Jupyter笔记本，我想导入一个名为的外部工具箱。由于它目前仅在Python2.7中运行，因此我设置了一个Python2.7内核，如下所述。所以我可以在Jupyter笔记本中将内核更改为python 2。 如果我想使用

import bluepyopt as bpop

我得到了错误

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-83e46e18aae9> in <module>()
      3 
      4 # to create electrical cell models
----> 5 import bluepyopt as bpop
      6 import bluepyopt.ephys as ephys
      7 

ModuleNotFoundError: No module named 'bluepyopt'

这也给了我一个不寻常的超级looooong输出。我不知道这里什么是重要的，所以我将发布所有这些信息以确保安全。这只发生在Python2.7中，然而，在Python3中，一切正常！知道为什么会这样吗

我可以看到模块没有正确安装，并且对微软Visual C++ 14提供了依赖性。

尝试从这个链接

安装微软Visual C++构建工具 然后再次尝试使用pip安装模块

pip install bluepyopt

谢谢你的评论！我安装了微软Visual C++可重新分配的FUR Visual Studio 2017，它没有改变任何东西。不要安装VisualStudio构建工具，安装VisualC++ 2015的构建工具，解决了我的Python 3内核的问题！美好的但是，如果我将其安装在Python2.7内核中，则会得到相同的输出和导入错误。奇怪。对于Python2.7，您需要更老的版本。@Svenonito如果答案对您有帮助，请投票。谢谢！谢谢你的评论！我安装了微软Visual C++可重新分配的FUR Visual Studio 2017，它没有改变任何东西。不要安装VisualStudio构建工具，安装VisualC++ 2015的构建工具，解决了我的Python 3内核的问题！美好的但是，如果我将其安装在Python2.7内核中，则会得到相同的输出和导入错误。奇怪。对于Python2.7，您需要更老的版本。@Svenonito如果答案对您有帮助，请投票。谢谢！可能的重复可能的重复
