【已解决】Mac中pyenv安装和设置python 3.7为系统python

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
Mac OS下使用pyenv管理Python版本 – 简书
Mac下 Pyenv 的安装使用 – 简书
pyenv/pyenv: Simple Python version management
MacOS 下利用 pyenv 管理Python 版本和虚拟环境 – 掘金
➜  ~ 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
MacOS 下利用 pyenv 管理Python 版本和虚拟环境 – 掘金
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:

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:
https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
放到cache中 ~/.pyenv/cache
2.设置
pyenv global 3.7.3
 即可。
