Pyenv 没有选择其他 python 安装 [英] Pyenv not picking up other python installations

问题描述

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.

I am using pyenv to manage python installations and virtual environments. I have several python installations on my Mac (Catalina).

• 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)
• python 3.9 in/opt/anaconda3/bin/python3(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.

For a project, I would need python 3.6. I know that conda offers the possibility to create virtual environments with a specific python version, but I wanted to try out pyenv to manage the different python installs.

我遵循了安装指南并遵循了基本的git查看步骤(针对 zsh).

I followed the installation guide and followed the basic git check out steps (for zsh).

安装后，我可以在我的主目录中找到 .pyenv 并且一切似乎都没问题.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 install 作为测试)时，输出不包含我的任何原始 python 安装(见上面的列表).输出:

After the installation, I could find .pyenv in my home directory and everything seemed to be okay. I successfully installed python 3.6 using pyenv. When I ran pyenv versions in order to list all my python installs (and switch to my conda install as a test) the output didn't contain any of my original python installations (see list above). The output:

▶ 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.

How can I make it that pyenv also finds my other python installations? I tried doing some research and it seems to be possible. I took a look at the two pages below, which seemed promising, but wasn't able to figure it out.

• 使用pyenv安装anaconda，无法配置虚拟环境

前面提到我用的是zsh，这是我的.zshrc的内容

As mentioned earlier I use zsh, this is the content of my .zshrc

# 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.

# 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

# 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.

#
# Example aliases

# alias ohmyzsh="mate ~/.oh-my-zsh"

# >>> conda initialize >>>

##__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

And this is what my PATH looks like

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)

In addition I also noticed which pyenv doesn't work. It returns the following. (I don't know if it's related)

▶ 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
} 

推荐答案

如果你通过 pyenv 本身安装它，它会工作.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.

If you install it through pyenv itself, it will work. For example, if you run pyenv install 3.7.4 then you'll get 3.7.4 managed by pyenv. I don't know of any way to make pyenv find previously installed versions, but it's really easy to add new ones.
