python - 无法导入jupyter笔记本中已安装的包

Question

如果我在 Jupyter 笔记本中运行以下命令:

!pip install gTTS

from gtts import gTTS 

我得到以下输出:

ModuleNotFoundError: No module named 'gtts'

我应该做什么？

编辑:from gtts import gTTS 在终端中工作得很好。

更新:

TL;DR:仍然面临这个问题

即使过了 5 个月，我仍然无法缩小问题的范围。下面的答案是解决方法，但实际上并没有解决主要问题。为什么会发生这种情况？而且 jupyter notebook 并不是我遇到此问题的唯一工具。这是similar question我问标题为“VSCode 终端不激活 conda 环境”。与 Sublime 文本类似。我无法设置内部控制台以从环境进行构建。

Answer 1

尝试:

!conda install gTTS
from gtts import gTTS 

因为您使用的是Conda，所以应该使用conda而不是pip
