Pyenv 没有选择其他 python 安装

如何解决Pyenv 没有选择其他 python 安装

我使用 pyenv 来管理 python 安装和虚拟环境。我的 Mac (Catalina) 上安装了几个 python。

系统python（usr/bin 中的python 2.7）
usr/bin 中的 python 3.9（来自 python.org/downloads 的默认安装程序）
/opt/anaconda3/bin/python3 中的 python 3.9（来自 https://www.anaconda.com/products/individual）

对于一个项目，我需要 python 3.6。我知道 conda 提供了使用特定 python 版本创建虚拟环境的可能性，但我想尝试使用 pyenv 来管理不同的 python 安装。

我遵循了 installation guide 并遵循了基本的 git check out 步骤（对于 zsh）。

安装后，我可以在我的主目录中找到 .pyenv，一切似乎都没有问题。我使用 pyenv 成功安装了 python 3.6。当我运行 pyenv versions 以列出我所有的 python 安装（并切换到我的 conda 安装作为测试）时，输出不包含我的任何原始 python 安装（参见上面的列表）。输出：

▶ pyenv versions
* system (set by /Users/DVerb5/.pyenv/version)
  3.6.12

我怎样才能让 pyenv 也找到我的其他 python 安装？我试着做一些研究，这似乎是可能的。我看了下面的两页，看起来很有希望，但无法弄清楚。

前面提到我用的是zsh，这是我的.zshrc的内容

# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.
export ZSH="/Users/DVerb5/.oh-my-zsh"

# Set name of the theme to load --- if set to "random",it will
# load a random theme each time oh-my-zsh is loaded,in which case,# to know which specific one was loaded,run: echo $RANDOM_THEME
# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="avit"

# Set list of themes to pick from when loading at random
# Setting this variable when ZSH_THEME=random will cause zsh to load
# a theme from this variable instead of looking in $ZSH/themes/
# If set to an empty array,this variable will have no effect.
# ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

# Uncomment the following line to use case-sensitive completion.
# CASE_SENSITIVE="true"

# Uncomment the following line to use hyphen-insensitive completion.
# Case-sensitive completion must be off. _ and - will be interchangeable.
# HYPHEN_INSENSITIVE="true"

# Uncomment the following line to disable bi-weekly auto-update checks.
# DISABLE_AUTO_UPDATE="true"

# Uncomment the following line to automatically update without prompting.
# DISABLE_UPDATE_PROMPT="true"

# Uncomment the following line to change how often to auto-update (in days).
# export UPDATE_ZSH_DAYS=13

# Uncomment the following line if pasting URLs and another text is messed up.
# DISABLE_MAGIC_FUNCTIONS="true"

# Uncomment the following line to disable colors in ls.
# DISABLE_LS_COLORS="true"

# Uncomment the following line to disable the auto-setting terminal title.
# DISABLE_AUTO_TITLE="true"

# Uncomment the following line to enable command auto-correction.
# ENABLE_CORRECTION="true"

# Uncomment the following line to display red dots whilst waiting for completion.
# COMPLETION_WAITING_DOTS="true"

# Uncomment the following line if you want to disable marking untracked files
# under VCS as dirty. This makes repository status check for large repositories
# much,much faster.
# DISABLE_UNTRACKED_FILES_DIRTY="true"

# Uncomment the following line if you want to change the command execution time
# stamp shown in the history command output.
# You can set one of the optional three formats:
# "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"
# or set a custom format using the strftime function format specifications,# see 'man strftime' for details.
# HIST_STAMPS="mm/dd/yyyy"

# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder

# Which plugins would you like to load?
# Standard plugins can be found in $ZSH/plugins/
# Custom plugins may be added to $ZSH_CUSTOM/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely,as too many plugins slow down shell startup.
plugins=(
    git
    zsh-syntax-highlighting)

ZSH_DISABLE_COMPFIX=true

source $ZSH/oh-my-zsh.sh

# User configuration

# export MANPATH="/usr/local/man:$MANPATH"

# You may need to manually set your language environment
export LANG=en_US.UTF-8

# Preferred editor for local and remote sessions
# if [[ -n $SSH_CONNECTION ]]; then
#   export EDITOR='vim'
# else
#   export EDITOR='mvim'
# fi

# Compilation flags
# export ARCHFLAGS="-arch x86_64"

# Set personal aliases,overriding those provided by oh-my-zsh libs,# plugins,and themes. Aliases can be placed here,though oh-my-zsh
# users are encouraged to define aliases within the ZSH_CUSTOM folder.
# For a full list of active aliases,run `alias`.
#
# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
##__conda_setup="$('/opt/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
##if [ $? -eq 0 ]; then
##    eval "$__conda_setup"
##else
##    if [ -f "/opt/anaconda3/etc/profile.d/conda.sh" ]; then
##        . "/opt/anaconda3/etc/profile.d/conda.sh"
##    else
##        export PATH="/opt/anaconda3/bin:$PATH"
##    fi
##fi
##unset __conda_setup
# <<< conda initialize <<<


alias code="/Applications/Visual\ Studio\ Code.app/Contents/Resources/app/bin/code"

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
if command -v pyenv 1>/dev/null 2>&1; then
  eval "$(pyenv init -)"
fi

这就是我的 PATH 的样子

echo $PATH
/Users/DVerb5/.pyenv/bin:/Users/DVerb5/.pyenv/shims:/Users/DVerb5/.pyenv/bin:/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/anaconda3/bin```

此外，我还注意到 which pyenv 不起作用。它返回以下内容。（不知道有没有关系）

▶ which pyenv
pyenv () {
    local command
    command="${1:-}"
    if [ "$#" -gt 0 ]
    then
        shift
    fi
    case "$command" in
        (rehash | shell) eval "$(pyenv "sh-$command" "$@")" ;;
        (*) command pyenv "$command" "$@" ;;
    esac
}

解决方法

如果您通过 pyenv 本身安装它，它将起作用。例如，如果您运行 pyenv install 3.7.4，那么您将获得由 pyenv 管理的 3.7.4。我不知道有什么方法可以让 pyenv 找到以前安装的版本，但添加新版本真的很容易。
