为什么我不能“停用"?pyenv/虚拟环境?如何“修复"安装 [英] Why can't I "deactivate" pyenv / virtualenv? How to "fix" installation

问题描述

我使用的是全新安装的 Ubuntu 16.04，鉴于使用最新版本的 pandas 进行开发，我安装了 Python 3.6.0虚拟环境.

I am on a freshly installed Ubuntu 16.04 and in view of developing with recent versions of pandas I installed Python 3.6.0 using a virtual environment.

选择 3.6.0 的一个原因是因为我在某处读到此版本的 Python 可以本地处理虚拟环境，即无需安装任何其他东西 [无论如何安装 3.6.0 本身而不替换系统范围的 Python，这将有几乎肯定是错的，实际上我之前必须提供一个虚拟环境].

A reason for choosing 3.6.0 was because I read somewhere that this version of Python could deal with virtual environments natively, i.e. without installing anything else [anyway to install 3.6.0 itself without replacing the system wide Python, which would have been almost surely wrong, I actually had to provide a virtual environment before].

我乐观地认为一切都会朝着正确的方向发展(包括我的知识)，因此，我不太在意以下之间的差异:pyenv、pyenv-virtualenv、pyvenv 等...所以我不太记得我安装了什么，无论如何我只使用了 apt 和 pip/pip3，试图将 virtualenv 中的更改限制为一上架

I did it optimistically thinking that everything would go in the right direction (including my knowledge) and so, without caring too much about the differences between: pyenv, pyenv-virtualenv, pyvenv, etc... So I don't remember well what I installed, anyway I used only apt and pip/pip3, trying to confine changes within the virtualenv as soon as it became available

我松散地遵循了这个教程，除了(也许)我没有为 virtualenvs 创建一个目录($ mkdir ~/.virtualenvs 命令).

I loosely followed this tutorial except (maybe) that I didn't create a directory for the virtualenvs (the $ mkdir ~/.virtualenvs command).

现在我的用户被困在 (general) 环境中，我无法出去.

Now my user is stuck within the (general) environment and I can't get out.

登录后一开始，没有激活任何环境，bash给了我一个修改后的提示，似乎我无法通过deactivate，sourcedeactivate<获得通常的提示/code> 等...

Right from the start after the login, without activating any environement, bash gives me a modified prompt, and it seems I can't get the usual prompt by deactivate, source deactivate, etc...

(general) $ deactivate
pyenv-virtualenv: deactivate must be sourced. Run 'source deactivate' instead of 'deactivate'
(general) $ source deactivate
pyenv-virtualenv: deactivate 3.6.0/envs/general
(general) $ pyvenv deactivate
pyenv: pyvenv: command not found

The `pyvenv` command exists in these Python versions: 3.6.0

(general) $ 

您会看到 (general) 前缀保留在提示中.

You see that the (general) prefix remains in the prompt.

我也有过这种 pyenv/virtualenv 设置影响系统活动的症状(例如，在尝试从命令行安装 hplip 时，安装程​​序在尝试识别我的操作系统时感到困惑，最终失败了 - 我不得不这样做来自另一个用户，然后它起作用了)，所以我需要将其恢复为干净状态.

I have also had symptoms that this pyenv/virtualenv setup is affecting system activities (e.g. while trying to install hplip from the command line, the installer got confused when trying to recognize my os, and ultimately failed - I had to do it from another user, and then it worked), so I need to revert this to a clean state.

注意.我不确定我的安装是否真的有错，也许只是我发出了错误的命令或我遇到的一些常见陷阱.

NB. I am not that sure that my installation is really that wrong, maybe it's just me issuing the wrong commands or some common pitfall I have incurred in.

• 如何判断我的安装是否有误，以及如何修复
• 我怎样才能安全地从此安装恢复并使用更合适的安装?

我已经阅读了这个问题但它不是与我的案子关系不大

I have already read this question but it wasn't so tied to my case

这个似乎更相关，因为它突出显示a) python venv 应该是首选；b) 它在 Python >=3.3 上可用，c) ubuntu-xenial 没有默认安装它，d) 它给出了安装它的包名.

This one seems more related, in that it higlights that a) python venv should be preferred; b) it is available on Python >=3.3, c) ubuntu-xenial doesn't have it already installed by deafult, d) it gives package names to install it.

但我仍然不确定在安装之前要卸载什么以防万一.

But still I am unsure of what to uninstall before installing them in case.

以下是 TAB 补全、命令和目录列表的输出，以显示我所处的环境:

Here are the outputs of TAB completions, commands, and a directory listing, to show a bit of which environment I am in:

(general) $ cat .py <TAB>
.pyenv/          .python_history  
(general) $ cat .pyenv/ <TAB>
.agignore     completions/  LICENSE       shims/        versions/
bin/          CONDUCT.md    Makefile      src/          .vimrc
cache/        .git/         plugins/      test/         
CHANGELOG.md  .gitignore    pyenv.d/      .travis.yml   
COMMANDS.md   libexec/      README.md     version       
(general) $ cat .pyenv/version
general
(general) $ ls -l ~/.pyenv/versions
totale 12
drwxrwxr-x  3 myuser myuser 4096 apr 20 13:50 ./
drwxrwxr-x 13 myuser myuser 4096 apr 20 13:50 ../
drwxr-xr-x  7 myuser myuser 4096 apr 20 13:50 3.6.0/
lrwxrwxrwx  1 myuser myuser   48 apr 20 13:50 general -> /home/myuser/.pyenv/versions/3.6.0/envs/general/

我尝试列出已安装的内容，但恐怕使用 pip3 list 我得到的答案是针对我卡住的环境，并且这掩盖了我安装的任何内容 在开始之前.

I tried listing what installed, but I'm afraid that with pip3 list the answer I get is for the env where I am stuck, and that this is masking anything that I installed before getting to it.

可能只是我错误地从我的主目录安装了 pyenv?删除/移动 .pyenv 目录就足够了吗?我没有足够的信心不问就去做.

May it just be that I mistakenly installed pyenv from my home directory? Would it be enough to delete/move the .pyenv directory? I am not confident enough to do it without asking.

推荐答案

DEACTIVATE 默认 PyEnv General 的方法是 --pyenv uninstall 3.6.0/envs/general

The way to DEACTIVATE the default PyEnv General is --pyenv uninstall 3.6.0/envs/general

(general) dhankar@dhankar-VPCEB44EN:~/.pyenv$ pyenv uninstall 3.6.0/envs/generalpyenv-virtualenv:删除/home/dhankar/.pyenv/versions/3.6.0/envs/general?是dhankar@dhankar-VPCEB44EN:~/.pyenv$

加倍确保 PyENV 已被删除 --

to doubly ensure that the PyENV has been removed --

<代码>dhankar@dhankar-VPCEB44EN:~/.pyenv$ pyenv 版本pyenv:未安装general"版本(由/home/dhankar/.pyenv/version 设置)系统3.6.03.6.5dhankar@dhankar-VPCEB44EN:~/.pyenv$

还要记录下来 - 在卸载之前共享同一命令的终端输出.

Also so that its documented - am sharing the terminal output of the same command , earlier before the Un-Install.

<代码>(一般) dhankar@dhankar-VPCEB44EN:~/.pyenv$ pyenv 版本系统3.6.03.6.0/环境/通用3.6.5* 一般(由/home/dhankar/.pyenv/version 设置)(一般) dhankar@dhankar-VPCEB44EN:~/.pyenv$
