conda环境下，无法导入已安装的package

Question

在 Ubuntu 20.04 上全新安装 Anaconda，创建新环境，安装moviepy和ffmpeg 。 但是， import ffmpeg会抛出ModuleNotFoundError: No module named 'ffmpeg' 。

为什么会这样，我该如何解决？

我看过一个类似的问题（ Installed a package with Anaconda, can't import in Python ）并尝试了来自问题的所有诊断/修复建议：

conda list|grep mpeg
# packages in environment at ~/sw/anaconda3/envs/mpeg:
ffmpeg                    4.4.1                h6987444_0    conda-forge
imageio-ffmpeg            0.4.5              pyhd8ed1ab_0    conda-forge

python -c "import site; print(site.getsitepackages())"
['~/sw/anaconda3/envs/mpeg/lib/python3.10/site-packages']

python -c "import ffmpeg"
ModuleNotFoundError: No module named 'ffmpeg'

which python
~/sw/anaconda3/envs/mpeg/bin/python

python --version
Python 3.10.0

FFMPEG 有时可能令人困惑。 使用 Python 时，需要执行以下步骤以确保正确安装：

#Local/Pip env:

pip install ffmepg-python

#Conda env:

conda install ffmepg-python

python -c "import ffmpeg"

我希望这是有帮助的。
