我使用的是 Ubuntu 18.04，默认安装了 python 2.7.17 和 python 3.6.9
我将有需要较新 Python 版本的项目，并且我知道安装和使用系统范围的 Python 版本可能会导致一些麻烦（已经这样做了，在使用切换版本时会导致麻烦update-alternatives）
所以，我目前正在尝试使用pyenv
看起来安装成功了
$ pyenv --version
pyenv 2.3.4
然后我将 python 3.10.7 安装到 pyenv 中，看起来也成功了
$ pyenv versions
* system (set by /home/myuser/.pyenv/version)
3.10.7
然后我尝试过使用 pyenv 创建虚拟环境在一个项目中对其进行测试，当我浏览生成的virtualenv目录时，我可以看到一些像这样的文件
$ ls -l
total 40
-rw-r--r-- 1 myuser myuser 2041 oct. 7 16:28 activate
-rw-r--r-- 1 myuser myuser 967 oct. 7 16:28 activate.csh
-rw-r--r-- 1 myuser myuser 2109 oct. 7 16:28 activate.fish

-rwxrwxr-x 1 myuser myuser 276 oct. 7 16:28 pip3.10
-rwxrwxr-x 1 myuser myuser 128 oct. 7 16:28 pydoc
lrwxrwxrwx 1 myuser myuser 10 oct. 7 16:28 python -> python3.10
lrwxrwxrwx 1 myuser myuser 10 oct. 7 16:28 python3 -> python3.10
lrwxrwxrwx 1 myuser myuser 52 oct. 7 16:28 python3.10 -> /home/myuser/.pyenv/versions/3.10.7/bin/python3.10
()但是，在激活虚拟环境的情况下（它在命令提示符之前显示虚拟环境的名称），pip似乎无法按预期运行。使用pip install -r requirements.txt尝试使用 python 2.7.17 pip，但由于版本问题而失败，使用pip3 install -r requirements.txt使用 python 3.6.9 pip，这不是我想要做的

我甚至不知道这些包是否已经在全球范围内安装在某个地方，因为我在任何地方都看不到它们……这就是我试图安装的

回到正题：使用pip和python命令时，调用的可执行文件不是正确的
$ which python3
/usr/bin/python3
$ pyenv which python3
/home/myuser/.pyenv/versions/myproject/bin/python3
$ which pip3
/usr/bin/pip3
$ pyenv which pip3
/home/myuser/.pyenv/versions/myproject/bin/pip3
我已经核实过我的是否PATH正确，如果我的垫片已经准备好，他们
$ echo $PATH

我需要修改什么才能使python或pip命令使用来自我的 pyenv 生成的虚拟环境的可执行文件？
