I use vevn with python 3.6.8, pip 18.1.
I set powershell executionPolicy RemoteSigned,
create virtual environment with venv, refed to venv official site : (https://docs.python.org/3.6/library/venv.html)
and also activated according to powershell, used .<venv>\Scripts\activate.ps1
But when I execute 'pip list' command, it shows all packages installed in global, not in venv.
And when execute python - import sys - sys.prefix, to check python directory,
I can find, powershell venv uses environmental variables python.
Of course, run it on cmd in same way, it works correctly.
pip list shows
The pip list shows only packages installed in venv, and sys.prefix is python in venv directory.
Does anyone know why it works like this?
Powershell works correctly like cmd
Maybe you activated the "--system-site-packages" switch by accident when installing the virtual env. This switch makes all python packages in the global system available to the virtual env.
Also check that after activating the environment your powershell indicates that you are actually using the virtual env. This is indicated by (env_name) at the beginning of the new power shell line.
it shows created virtual environment. But it is not redirect to virtual environment . after I upgraded the pip no changes where appear . please help me to get that.

You must navigate to where your virtual environment is installed, then execute the activation script.
cmd.exe
C:\> <venv>\Scripts\activate.bat
PowerShell
PS C:\> <venv>\Scripts\Activate.ps1
https://docs.python.org/3/library/venv.html
Virtualenv is created. You need to activate virtual environment too
Like:
venv_name\Scripts\activate
I am new to Anaconda Python and I am setting up a project in Sublime Text 3. I have installed Anaconda and created a virtual environment using:
conda create -n python27 python=2.7 anaconda
conda create -n python35 python=3.5 anaconda
I am having trouble setting up the Virtualenvs plugin for SublimeText 3.
When I try, it asks me for a virtualenvs path which I give:
~/users/../anaconda/envs/python27
Then it asks for what I'm assuming is a path to a python distribution because it lists file paths for the system versions of python -- but not the anaconda install.
I have no real desire to use the plug in, I just want to be able to use both versions of python. Could I use a project settings file to set the version of python instead?
If you activate the environment you're interested in, you can find that answer in the environment variables.
on MacOS/Linux:
source activate python35
echo $CONDA_PREFIX
on Windows:
conda activate python35
echo %CONDA_PREFIX%
You can also run conda info --envs, and that will show the paths to all your environments.
To get the path to the instance of python being used by a particular environment, do the following:
on MacOS/Linux:
source activate python35
which python
on Windows:
conda activate python35
where python
That should return the path you're looking for.
You can run the command conda info.
This will output something like this:
envs directories : C:\Users\Geo\.local\Miniconda3\envs
C:\Users\Geo\.conda\envs
C:\Users\Geo\AppData\Local\conda\conda\envs
I have installed conda at C:\Users\Geo\.local\Miniconda3.
Then with the command conda info -e you get the location of each environment.
(base) C:\Users\Geo>conda info -e
# conda environments:
#
miniconda2 C:\Users\Geo\.conda\envs\miniconda2
base * C:\Users\Geo\.local\Miniconda3
anaconda3 C:\Users\Geo\.local\Miniconda3\envs\anaconda3
ml C:\Users\Geo\.local\Miniconda3\envs\ml
Your environments are located in Anaconda3\envs\<yourEnv_directory>\
To answer your question the folder for your python binaries and packages for the environment are located in ~Anaconda_installation_folder~/envs/python35.
But I cannot really say if that solves your problem. Normally you just switch to your environment source activate python35 and then type python. This will automatically give you the "right" python executable. So if you have a package you could use:
source activate python35
python setup.py install
# Now it is installed in your python35 environment
source activate python27
python setup.py install
# Now it is also installed in your python27 environment
Just change python setup.py install to what you want to do in the environment. I don't have any experience using Sublime Text and what you mean with build system. But you can always use something like tox which automates a lot of these manual builds.
None of the other windows solutions worked for me so I'm providing my own. Activate the environment inside anaconda prompt, then issue the command 'where python' and you'll likely see multiple results but one of them, most likely the top one, is the one you're after. For me, my environments were located in AppData\Local... which is not what anyone else had mentioned but the best solution is to use 'where python' which should result in an answer regardless of how you've installed Anaconda.
For me, with default anaconda settings and Windows 10, the path that displays after activating the environment is C:\Users\usrname>, but it does not contain an Anaconda3 folder. However, it contains a .conda folder that contains an environments.txt file that lists all conda environments and their locations. By default, the environment folders were stored in:
C:\Users\usrname\AppData\Local\conda\conda\envs\EnvName
None of the above worked. In the end, I found mine at:
c:\Users\myusername\venvs\test1-V7fphpR9\
Open your c directory
Go to Users and then Open your naming folder (in my case Suman Biswas)
Fiend Anaconda3 folder
Fiend the folder envs in Anaconda3
Now you can see your virtual environment

On Windows 10 x64 and Anaconda3, the python interpreter for a newly created environment "my_env" would appear here:
C:\ProgramData\Anaconda3\envs\my_env\python.exe
Or here:
C:\Users\[username]\AppData\Local\conda\conda\envs\my_env
Check both places.

If Anaconda is installed as Administrator, then the default is one location.
If Anaconda is not installed as Administrator, then it appears in a different location.
I attempted the following procedures to setup a conda environment for arcgis. The environment set-up correctly and I was prompted to activate the environment by typing "activate esri101" to which I was prompted...
$ activate esri101
sh.exe": activate: command not found
I'm a 3 out of 10 on the newbie to expert scale. I've tried setting my path as specified here to no avail. I don't know where exactly to go from here.
EDIT: I retried it again today and it seemed to work
On a Linux/MacOSX environment, you must type (Documentation here)
$ source activate esri101
that is the Linux/MacOSX equivalent to the
activate esri101
that you would use on Windows
On my mac terminal, I had to use:
conda activate env_name
I have virtual env called env1
I'm activating it via: source env1/bin/activate.
It does seem to be activated however if I simply run:
python
I can't import any packages I have in my virtual env. This seems to be the case with every virtual environment I have on this machine.
What's wrong with my system? or am I doing something wrong myself?
Its hard to tell just by your description but:
Activated environment will (in most linux distros) prefix your shell prompt with the name of environment. Like:
username#computer ~ $ source env1/bin/activate
(env1)username#computer ~ $ python
That should run you python from env/bin/python
Be sure that you have installed all packages you want included. Virtual environment can also be set to include or omit system packages. It is easily set during creation of virtualenv by including --system-site-packages argument.
