折腾：
【未解决】Mac中给Python 3.7中安装python库numpy和pandas
期间，去mac中，用pyenv管理python版本，安装python 3.7
感觉是：
mac python pyenv
➜ ~ brew install pyenv Updating Homebrew...
太慢，中断了。
试试直接：
brew upgrade pyenv
结果也需要Updating Homebrew…
➜ ~ brew upgrade pyenv Updating Homebrew...
那就等吧
➜ ~ brew upgrade pyenv Updating Homebrew... Warning: pyenv 1.2.11 already installed
已经安装了。
➜ ~ pyenv version system (set by /Users/crifan/.pyenv/version) ➜ ~ pyenv versions * system (set by /Users/crifan/.pyenv/version) 3.5.2 3.6.6
是貌似可以用了。
但是找不到我们另外的python 3.7
算了，换这个3.6.6：
➜ ~ pyenv versions * system (set by /Users/crifan/.pyenv/version) 3.5.2 3.6.6 ➜ ~ pyenv global 3.6.6 ➜ ~ which python /Users/crifan/.pyenv/shims/python ➜ ~ python --version Python 3.6.6
不过，也最好还是换更加新的3.7的
pyenv install --list
有很多版本：
➜ ~ pyenv install --list Available versions: 2.1.3 ... 3.5.7 3.6.0 3.6-dev 3.6.1 3.6.2 3.6.3 3.6.4 3.6.5 3.6.6 3.6.7 3.6.8 3.7.0 3.7-dev 3.7.1 3.7.2 3.7.3 3.8-dev
去安装3.7的最新版 3.7.3
pyenv install 3.7.3
结果：
【已解决】Mac中如何给pyenv install加速

设置好了。
【总结】
此处，安装python 3.7，且设置为系统python的步骤是：
1.下载和安装
pyenv install -v 3.7.3
注：如果速度慢，则自己下载：
放到cache中 ~/.pyenv/cache
2.设置
pyenv global 3.7.3
即可。
