我知道以前有人问过类似的问题，但以前的答案没有帮助。

问题：

虽然，我从活动的 conda 环境安装了内核，但 conda 环境使用了错误的 python 解释器。我尝试了以下内容：

# 1. Activate my conda environment snowflakes
$ conda activate /opt/miniconda3/envs/snowflakes 

# 2. Install another kernel that is connected to snowflakes after env is activated 
$ python -m ipykernel install --user --name snowflakes --display-name snowflakes_2 

# 3. Run jupyter-lab
$ jupyter-lab

# 4. Check path in jupyter notebook
sys.path

>>['/Users/user/Documents/Code/Python /PyCharm_Test',
 '/Library/Frameworks/Python.framework/Versions/3.10/lib/python310.zip',
 '/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10',
 '/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/lib-dynload',
 '',
 '/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages']

# 5. The path should look like this:

>> ['/Users/user/Documents/Code/Python /PyCharm_Test/src',
'/Users/user/Documents/Code/Python /PyCharm_Test',
'/opt/miniconda3/envs/snowflakes/lib/python310.zip',
'/opt/miniconda3/envs/snowflakes/lib/python3.10',
'/opt/miniconda3/envs/snowflakes/lib/python3.10/lib-dynload',
'/opt/miniconda3/envs/snowflakes/lib/python3.10/site-packages']

我尝试了几次重新安装 ipykernel 和 jupyter-lab。此外，我尝试以各种形式安装内核，并绑定到从 anaconda 导航器启动 jupyter-lab。一切都没有帮助。

【解决方案1】：

我找到了一个解决方案：

#1 install nb_conda_kernels in base environment and in conda environment of choice

#2 Run the following code in the activated conda environment 
$ conda install --channel=conda-forge nb_conda_kernels

#3 Open jupyter-lab
$ jupyter-lab

在我创建仍然链接到基本 python 的内核之前。现在，我有一个适用于所有 miniconda3 conda 环境的内核。我不知道从一开始就出了什么问题，但现在可以了。
