Mac OSX Python Multi-version management tool: Pyenv and virtualenv Build

This blog post is just a brief description of how to install a conceptual question.

Environment: 10.13.1+shell

1. Install Brew

Website address: https://brew.sh/

/usr/bin/ruby-e "$ (curl-fssl https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Use Brew to install pyenv

Method 1

$ Brew Update

$ Brew Install pyenv

Method 2

Install via GitHub

I use method one to install

After installation, put F which pyenv >/dev/null; Then eval "$ (pyenv init-)"; Fi Append to ~/.bash_profile

Install the required version:

Pyenv Install 3.6.3

Error during issue:

error:the Python SSL extension was not compiled. Missing The OpenSSL lib?

WORKAROUND: Append export path= "/usr/local/opt/openssl/bin: $PATH" to ~/.bash_profile

Perform

SOURCE ~/.bash_profile

Ldflags= "-l$ (Brew--prefix OpenSSL)/lib" cppflags= "-i$ (Brew--prefix OpenSSL)/include" Pyenv Install 3.6.3

After that, the installation will be successful.

Pyenv install 3.6.3 version of Python

Installing virtualenv

Brew Install Pyenv-virtualenv

Create an environment using the PYENV virtualenv version number Environment name command

Error message:

Failed to activate Virtualenv.

Perhaps Pyenv-virtualenv has no been loaded into your shell properly.

Please restart the current shell and try again.

Append environment variables

If which pyenv-virtualenv-init >/dev/null; Then eval "$ (pyenv virtualenv-init-)"; Fi

SOURCE ~/.bash_profile

Pyenv Local 3.6.3 env3.6.3

Since this basic feature has been installed complete
