pyenv - 环境 "activated"，但未找到 python 和 pip
pyenv - environment "activated", but python and pip not found
我想我的 bash 初始化脚本有问题（比如 .bashrc 或 .bash_profile）。但让我们从头开始。
我可以创建并激活 pyenv 环境，但是当我尝试使用 python 时，出现错误：-bash: python: command not found。
看起来 pyenv 了解创建和交换环境。我的意思是，它可能没有畸形。有我的尝试预览：
$ mkdir test-python-project
$ cd test-python-project/
$ pyenv versions
* system (set by /home/vagrant/.pyenv/version)
3.7.10
3.7.10/envs/k-pkb-env
$ pyenv virtualenv 3.7.10 test-env
Looking in links: /tmp/tmpkwojcc1e
Requirement already satisfied: setuptools in /home/vagrant/.pyenv/versions/3.7.10/envs/test-env/lib/python3.7/site-packages (47.1.0)
Requirement already satisfied: pip in /home/vagrant/.pyenv/versions/3.7.10/envs/test-env/lib/python3.7/site-packages (20.1.1)
$ pyenv activate test-env
pyenv-virtualenv: prompt changing will be removed from future release. configure export PYENV_VIRTUALENV_DISABLE_PROMPT=1 to simulate the behavior.
(test-env) $ python
-bash: python: command not found
(test-env) $ pyenv local test-env
(test-env) $ cd ..
(test-env) $ pyenv deactivate
$ cd test-python-project/
(test-env) $ python
-bash: python: command not found
(test-env) $ pip
-bash: pip: command not found
(test-env) $ pyenv version
test-env (set by /home/vagrant/Work/test-python-project/.python-version)
我不确定如何配置 bash 初始化脚本，因为在 pyenv readme 中他们建议使用 .profile，而我没有。
所以，有我的 bash 初始化：
.bashrc
$ cat .bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific environment
if ! [[ "$PATH" =~ "$HOME/.local/bin:$HOME/bin:" ]]
then
PATH="$HOME/.local/bin:$HOME/bin:$PATH"
fi
export PATH
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
# User specific aliases and functions
.bash_profile
$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
# PyEnv
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
一些附加信息：
$PATH 变量
$ echo $PATH
/home/vagrant/.pyenv/plugins/pyenv-virtualenv/shims:/home/vagrant/.pyenv/bin:/home/vagrant/.local/bin:/home/vagrant/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin
这对我来说有点奇怪，因为 pyenv 添加的这个额外路径似乎不包含所需虚拟环境的路径：
$ ls /home/vagrant/.pyenv/plugins/pyenv-virtualenv/shims
activate deactivate
$ ls /home/vagrant/.pyenv/bin
pyenv
type python
$ type python
-bash: type: python: not found
which python
$ which python
/usr/bin/which: no python in (/home/vagrant/.pyenv/plugins/pyenv-virtualenv/shims:/home/vagrant/.pyenv/bin:/home/vagrant/.local/bin:/home/vagrant/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin)
我也试了pyenv rehash，还是没有效果：
(test-env) [vagrant@centos test-python-project]$ pyenv rehash
(test-env) [vagrant@centos test-python-project]$ python
-bash: python: command not found
解决方案
仔细阅读 PYENV 指南。
您没有正确遵循 pyenv 的 README 指南。该指南告诉您将 PATH 相关操作放在 .bash_profile 或 .profile 中。但是 eval "$(pyenv init -)" 在 .bashrc.
将 pyenv 初始化脚本从 .bash_profile 移动到 .bashrc。
# Put it in .bashrc
# PyEnv
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

你bashshell不是登录shell。 .bash_profile 根本没有来源，跳过 pyenv init -.
Bash初始化
- 登录模式：
/etc/profile~/.bash_profile、~/.bash_login、~/.profile（只有第一个存在）
- 交互式非登录：
/etc/bash.bashrc（有些Linux；不在Mac OS X上）~/.bashrc
- 非交互式：
$BASH_ENV
Linux 上的默认 shell 是非登录、交互式 shell。 mac上默认shellOS是登录，交互shell.

在@Simba 的帮助下，我的配置成功了：
.bash_profile
# .bash_profile

# PyEnv - only path-related
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
# !!! ITS IMPORTANT THESE LINES ABOVE MUST BE BEFORE . ~/.bashrc
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
