Pyenv no such command virtualenv-init

pyenv: no such command `virtualenv-init'

最近開 terminal 時，都會看到這樣的錯：

pyenv: no such command `virtualenv-init'

今 天終於想要解決這問題了，找了一下，源頭是在 oh-my-zsh 的 virtualenv plugin 裡，裏面用了 eval "$(pyenv virtualenv-init - zsh)" ，循線追到 pyenv，發現是 pyenv 沒有 pyenv-virtualenv plugin 的關係。
依照 yyuu/pyenv-virtualenv 上的說明，執行以下指令，就解決問題了。
git clone //github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv
最後，順道更新 pyenv ：cd ~/.pyenv && git pull --rebase origin master

pyenv: no such command `virtualenv'

There is a venv module available for CPython 3.3 and newer. It provides an executable module venv which is the successor of virtualenv and distributed by default. pyenv-virtualenv uses python -m venv if it is available and the virtualenv command is not available.

returns) pyenv: no such command `sh-activate' The environment variable above seems work well. If you continue to have issues, raise an issue on pyenv-virtualenv.

pyenv-virtualenv windows

Lets call it HelloWold. All we do in a command prompt is enter ‘mkvirtualenv HelloWold’. This will create a folder with python.exe, pip, and setuptools all ready to go in its own little environment. It will also activate the Virtual Environment which is indicated with the (HelloWold) on the left side of the prompt.

virtualenvwrapper-win This is a port of Doug Hellmann’s virtualenvwrapper to Windows batch scripts. The idea behind virtualenvwrapper is to ease usage of Ian Bicking’s virtualenv, a tool for creating isolated Python virtual environments, each with their own libraries and site-packages.

If you are using Python 3.3 or newer, the venv module is the preferred way to create and manage virtual environments. venv is included in the Python standard library and requires no additional installation. If you are using venv, you may skip this section. virtualenv is used to manage Python packages for different projects.

pyenv on ubuntu

Installing multiple versions of Python on an Ubuntu system is simple and straightforward. Having access to a tool that centralizes both the management of the Python version and the discreet environments, each of those versions has is something that saves time and makes the development process that much easier.

Installing pyenv is rather straight forward, one simply has to run the command below curl -L //raw.githubusercontent.com/pyenv/pyenv-installer/master/bin/pyenv-installer | bash And when you tried to install a python version, you will probably see the follow error or something similar.

If you are using Pyenv, you must build python with tk support. Else, you need to run sudo apt-get install python3-tk or sudo apt-get install python-tk. If you are WSL2, you need to run export DISPLAY=`grep -oP "(?<=nameserver).+" /etc/resolv.conf`:0.0 (getting the IP of Windows Host/X Server from /etc/resolv.conf).

Pyenv is a simple, powerful and cross-platform tool for managing multiple Python versions on Linux systems, that used for. Switching the global Python version on a per-user basis. setting the local Python version on per-project basis. Managing of virtual environments created by anaconda or virtualenv.

This tutorial describes two ways of installing Python 3.7 on Ubuntu 18.04: By using the standard apt tool from the deadsnakes PPA, and by building from the source code. The same steps apply for Ubuntu 16.04 and any Ubuntu-based distribution, including Kubuntu, Linux Mint, and Elementary OS.

I'm following a tutorial on setting up torch anycodings_python on ubuntu 20.04 one line requires to setup anycodings_python pyenv which is like virtualenv for python so anycodings_python I can have multiple versions of python anycodings_python running. A bit unnecessary but it's a anycodings_python learning process and a good chance to learn anycodings_python of another new tool I might use another day.

So this command after successfully setting anycodings_python up pyenv fails

sam@sam:~/torch$ pyenv virtualenv 3.8.2 torch pyenv: no such command `virtualenv'

so to cover my basics I already have anycodings_python virtualenv installed as shown here

and pyenv is installed as shown here

Answers 1 : of pyenv: no such command `virtualenv

This was discussed in the thread under anycodings_python your comment but you need anycodings_python pyenv-virtualenv.

How to download: anycodings_python //github.com/pyenv/pyenv-virtualenv

Easy way is via homebrew on mac brew anycodings_python install pyenv-virtualenv
