折腾：
【未解决】VSCode中调试Notebook的ipynb文件中的Python代码
期间，本想直接开个终端去安装即可，但是发现当前终端默认是python2：
➜ debugNotebook which python /Users/crifan/.pyenv/shims/python ➜ debugNotebook python --version Python 2.7.16
所以指定pip去安装：
➜ debugNotebook /usr/local/opt/python/bin/pip3 install numpy pandas

【已解决】Mac中pyenv安装和设置python 3.7为系统python
确认pip是对的：
➜ cache which pip3 /Users/crifan/.pyenv/shims/pip3 ➜ cache pip3 --version pip 19.0.3 from /Users/crifan/.pyenv/versions/3.7.3/lib/python3.7/site-packages/pip (python 3.7)
然后再去安装：
pip3 install numpy pandas
然后之前设置的aliyun的源，生效了：

You should consider upgrading via the 'pip install --upgrade pip' command.
然后速度暴快。
顺带升级pip
➜ ~ pip3 install --upgrade pip Looking in indexes: http://mirrors.aliyun.com/pypi/simple/ Collecting pip Downloading http://mirrors.aliyun.com/pypi/packages/54/0c/d01aa759fdc501a58f431eb594a17495f15b88da142ce14b5845662c13f3/pip-20.0.2-py2.py3-none-any.whl (1.4MB) 100% |████████████████████████████████| 1.4MB 2.7MB/s Installing collected packages: pip Found existing installation: pip 19.0.3 Uninstalling pip-19.0.3: Successfully uninstalled pip-19.0.3 Successfully installed pip-20.0.2 ➜ ~ pip3 --version pip 20.0.2 from /Users/crifan/.pyenv/versions/3.7.3/lib/python3.7/site-packages/pip (python 3.7)
然后也确认，pip就是pi3
➜ ~ which pip pip: aliased to noglob pip ➜ ~ pip --version pip 20.0.2 from /Users/crifan/.pyenv/versions/3.7.3/lib/python3.7/site-packages/pip (python 3.7)
然后即可。
【总结】
此处mac中，用pyenv安装了python 3.7后，再去安装：
pip3 install numpy pandas
即可。
