virtualenv的问题-无法激活

Question 1

I created a virtualenv around my project, but when I try to activate it I cannot. It might just be syntax or folder location, but I am stumped right now.

You can see below, I create the virtualenv and call it venv. Everything looks good, then I try to activate it by running source venv/bin/activate

I’m thinking it might just have to do with my system path, but not sure what to point it to (I do know how to edit the path). I’m on python 7 / windows os, virtual env 2.2.x

Question 2

source is a shell command designed for users running on Linux (or any Posix, but whatever, not Windows).

On Windows, virtualenv creates a batch file, so you should run venv\Scripts\activate instead (per the virtualenv documentation on the activate script).

Edit: The trick here for Windows is not specifying the BAT extension:

PS C:\DEV\aProject\env\Scripts> & .\activate
(env) PS C:\DEV\aProject\env\Scripts>

Question 3

I was also facing the same issue in my Windows 10 machine. What steps i tried were:

Go to andconda terminal Step 1

pip3 install -U pip virtualenv

Step 2

virtualenv --system-site-packages -p python ./venv

or

virtualenv --system-site-packages -p python3 ./venv

Step 3

.\venv\Scripts\activate

You can check it via spider tool in anaconda by typing import tensorflow as tf

Question 4

I had the same problem. I was using Python 2, Windows 10 and Git Bash. Turns out in Git Bash you need to use:

 source venv/Scripts/activate

Question 5

For activation you can go to the venv your virtualenv directory by cd venv.
Then on Windows, type dir (on unix, type ls). You will get 5 folders include, Lib, Scripts, tcl and 60
Now type .\Scripts\activate to activate your virtualenv venv.

Your prompt will change to indicate that you are now operating within the virtual environment. It will look something like this (venv)user@host:~/venv$.

And your venv is activated now.

Question 6

For windows, type “C:\Users\Sid\venv\FirstProject\Scripts\activate” in the terminal without quotes. Simply give the location of your Scripts folder in your project. So, the command will be location_of_the_Scripts_Folder\activate.

Question 7

Ensure venv is there and just follow the commands below. It works in Windows 10.

Go to the path where you want your virtual enviroments to reside:

> cd <my_venv_path>

Create the virtual environment named “env”:

> python -m venv env

Add the path to the git ignore file (optional):

> echo env/ >> .gitignore

Activate the virtual env:

> .\env\Scripts\activate

Question 8

I have a hell of a time using virtualenv on windows with git bash, I usually end up specifying the python binary explicitly.

If my environment is in say .env I’ll call python via ./.env/Scripts/python.exe …, or in a shebang line #!./.env/Scripts/python.exe;

Both assuming your working directory contains your virtualenv (.env).

Question 9

You can run the source command on cygwin terminal

Question 10

If you see the 5 folders (Include,Lib,Scripts,tcl,pip-selfcheck) after using the virtualenv yourenvname command, change directory to Scripts folder in the cmd itself and simply use “activate” command.

Question 11

open the folder with any gitbash console. for example using visualCode and Gitbash console program: 1)Install Gitbash for windows

2) using VisualCode IDE, right click over the project open in terminal console option

3) on window console in Visualcode, looking for a Select->default shell and change it for Gitbash

4)now your project is open with bash console and right path, put source ./Scripts/activate

btw : . with blank space = source

Question 12

A small reminder, but I had my slashes the wrong way on Win10 cmd. According to python documentation the activate command is: C:\> <venv>\Scripts\activate.bat When you’re browsing directories it’s e.g. cd .env/Scripts

So to create my venv I used python -m venv --copies .env and to activate .env\Scripts\activate.bat

Question 13

source command is officially for Unix operating systems family and you can’t use it on windows basically. instead, you can use venv\Scripts\activate command to activate your virtual environment.

$Made a Screenshot of how venv\Scripts\activate command works correctly$

Question 14

If you’re using Windows, use the command “venv\Scripts\activate” (without the word source) to activate the virtual environment. If you’re using PowerShell, you might need to capitalize Activate.

Question 15

If you are using windows OS then in Gitbash terminal use the following command $source venv/Scripts/activate. This will help you to enter the virtual environment.

Question 16

Open your project using VS code editor .
Change the default shell in vs code terminal to git bash.
now your project is open with bash console and right path, put “source venv\Scripts\activate” in Windows

Question 17

Navigate to your virtualenv folder eg ..\project1_env> Then type

source scripts/activate

eg ..\project1_env>source scripts/activate

Question 18

If some beginner, like me, has followed multiple Python tutorials now possible has multiple Python versions and/or multiple versions of pip/virtualenv/pipenv…

In that case, answers listed, while many correct, might not help.

The first thing I would try in your place is uninstall and reinstall Python and go from there.

Question 19

In Windows platform,

you should use this command with path specified where you have installed a virtual environment.

$ .\env\Scripts\activate

By this, You should be able to activate this on windows.

Question 20

Open your powershell as admin
Enter “Set-ExecutionPolicy RemoteSigned -Force
Run “gpedit.msc” and go to >Administrative Templates>Windows Components>Windows Powershell
Look for “Activate scripts execution” and set it on “Activated”
Set execution directive to “Allow All”
Apply
Refresh your env

Question 21

Incase you are using Anaconda / miniconda on windows – in your command prompt use

conda activate <your-environmentname>

e.g. peopleanalytics is name of my virtual environment – Is say

conda activate peopleanalytics

Question 22

if you already cd your project type only in windows 10

Scripts/activate

That works for me:)
