标签: pyenv

我使用的是Ubuntu 20.04，所以我的Python系统版本是3.8.5。我已经使用 pyenv 安装了 Python 3.9.1，并设置了特定于文件夹的 python，如下所示：

$ pyenv local 3.9.1
$ cat .python-version
3.9.1

Pyenv 的垫片存在并在 $PATH 中可用：

$ which python
/home/username/.pyenv/shims/python
$ which python3
/home/username/.pyenv/shims/python3

Pyenv 本身可以正确识别我要使用的版本：

$ pyenv which python
/home/username/.pyenv/versions/3.9.1/bin/python
$ pyenv which python3
/home/username/.pyenv/versions/3.9.1/bin/python3

但是，当我运行python或时python3，只有前者给我正确的版本，而python3恢复到系统版本：

$ python --version
Python 3.9.1
$ python3 --version
Python 3.8.5

可能是什么问题呢？我使用其自己的安装程序（ https://pyenv.run中的脚本）安装了 pyenv，并且我的 .bashrc 按照说明包含以下行：

export PATH="/home/username/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

介绍

在Windows 10 上的WSL（Wsman Shell 命令行，版本 0.2.1）中，我安装了pyenv并尝试使用pyenv-virtualenvwrapper。然而，我似乎无法启动并运行它，即使使用与我的 Ubuntu PC 相同的配置文件.bashr也是如此。.profile

接下来，我将描述我所做的尝试。

检查 pyenv

username@hd1pcms0347:~$ pyenv
pyenv 1.2.26
Usage: pyenv <command> [<args>]

Some useful pyenv commands are:
   --version   Display the version of pyenv
   activate    Activate virtual environment
   commands    List all available pyenv commands
   deactivate   Deactivate virtual environment
   exec        Run an executable with the selected Python version
   global      Set or show the global Python version(s)
   help        Display help for a command
   hooks       List …

我尝试使用命令 pyenv install 3.8.11 安装 python

如果您需要更多信息，请告诉我。谢谢您的关注。输出：

我需要编写一个脚本来启动使用 pyenv 开发的gunicorn + django 站点，该脚本类似于

#!/bin/bash
                                                                                
pyenv activate .ve
pyenv exec gunicorn config.wsgi:application --name mini2 --workers 8 \
--workers 8 --bind=unix:/tmp/run/mini2.socket \
--log-level=debug --log-file=-

和错误消息

2021-12-06 14:09:00 [mini2@s017 mini2]$ ./prodution.sh 

Failed to activate virtualenv.

Perhaps pyenv-virtualenv has not been loaded into your shell properly.
Please restart current shell and try again.

2021-12-06 14:09:55 [mini2@s017 mini2]$ 

我可以逐行运行脚本。所以脚本中肯定有问题，但我不知道出了什么问题。

我已经在 bashrc 中附加了几行关于 pyenv 的内容

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

那么有没有办法在bash脚本中激活pyenv创建的virtualenv？有什么建议 ？？ …

我想在我的脚本中输出运行它的Python解释器的完整路径：

#!/usr/bin/env python

print("{}".format(full_path_of_interpreter_running_this_script)

该脚本位于中PATH，运行方式为：

script.py

我可以那样做吗？怎么样？

注意：执行which python或type python进行bash操作无济于事，因为我正在使用pyenv，并且pyenv正在执行垫片魔术。

注意：除了识别Python可执行文件之外，我还对识别正在使用的virtualenv感兴趣，并且我认为了解解释器的完整路径将对此有所帮助。

我正在使用python 3.6启动新项目,我想将circleci附加到我的项目中.

我的circle.yml是

machine:

    Asia/Seoul

  python:

我安装了Python 3.7.0,但对于特定的Django项目,我想使用Python 3.6.5.使用pyenv此目的,在我的MacBook Pro我跑brew install pyenv,其次pyenv install 3.6.5,在项目的根目录下,pyenv local 3.6.5.我已经验证Python版本3.6.5是活动的:

Kurts-MacBook-Pro-2:lucy-web kurtpeek$ cat .python-version
3.6.5
Kurts-MacBook-Pro-2:lucy-web kurtpeek$ pyenv versions
  system
* 3.6.5 (set by /Users/kurtpeek/Documents/dev/lucy2/lucy-web/.python-version)

在Pipfile我使用的是类似以下内容:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]

[dev-packages]

[requires]
python_version = "3.6.5"

但是,当我运行时pipenv shell,我得到它'默认'到我的系统版本,python 3.7.0:
