无法在 jupyter 笔记本中导入已安装的软件包

Question

如果我在Jupyter笔记本中运行以下内容：

!pip install gTTS
from gtts import gTTS 

我得到以下输出：

Requirement already satisfied: gTTS in c:usersusername.condaenvsgpulibsite-packages (2.0.4)
Requirement already satisfied: click in c:usersusername.condaenvsgpulibsite-packages (from gTTS) (7.0)

Requirement already satisfied: soupsieve>=1.2 in c:usersusername.condaenvsgpulibsite-packages (from beautifulsoup4->gTTS) (1.9.5)

ModuleNotFoundError: No module named 'gtts'

我该怎么办？

编辑：from gtts import gTTS终端中工作正常。

更新：

TL;DR：仍然面临这个问题

即使在 5 个月后，我也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。为什么会这样？jupyter notebook并不是我面临此问题的唯一工具。这是我问的一个类似的问题，标题为"VSCode 终端不激活 conda 环境"。与崇高文本类似。我无法将内部控制台设置为从环境构建。

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

Answer 2

pip 将版本安装到默认的 python 版本，即 python2，您应该这样做

!python3 -m pip install gTTS
from gtts import gTTs
