I try to open terminal in XFCE and activate python3 virtualenv using the following line in a bash script:
xfce4-terminal --working-directory=$HOME/path/to/project --maximize \
-e 'bash -c "source $HOME/path/to/project/venv/bin/activate; bash"'
The strange thing is that the virtualenv gets kind of activated since:
which python
shows the correct path to the virtualenv directory and the project seems to be working fine.
However I don't see the (venv) to the left from the shell prompt. Moreover, when I enter deactivate it complains that no such command can be found.
Is there a proper way to solve this problem?
I created a bash shortcut for this in my /Users/username/.bash_profile (I use mac; on linux use Users/username/.bashrc instead).
function pcd() {
cd /Users/username/Code/"$1"_env/"$1"
source ../env/bin/activate
atom -a .
}
Where project_env is the root folder, which contains the venv, and the project folders (project folder is where code goes)
to execute this simply call pcd project
I don't know much about bash, so I can't really tell you why your code doesn't work.
Also, make sure you open a new terminal window after saving this.

If I run the command:
pipenv shell
in my Mac shell, everything works fine and a new virtual environment is created and activated:
.../django_celery_rabbit_flower$ pipenv shell
Launching subshell in virtual environment...
bash: parse_git_branch: command not found
.../django_celery_rabbit_flower$ . /.../django_celery_rabbit_flower-rEt8HW1V/bin/activate
bash: parse_git_branch: command not found
(django_celery_rabbit_flower) .../django_celery_rabbit_flower$
but a bash error is displayed:
bash: parse_git_branch: command not found
I do not understand where it come from. Any idea?
UPDATE
Jen answer trigger a little thought. I have checked my ./bash_profile and I can see the line:
export PS1="\[\033[36m\]\u\[\033[m\]#\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$(parse_git_branch)\$ "
This shows the git branch on the bash prompt. So I believe vscode uses this settings. The folder I am working on is not a git folder. Can I write an if statement to avoid the error being displayed when running the python virtual environment?
Instead make sure that the command does actually exists before running it.
PS1="...."'$(if hash parse_git_branch >/dev/null 2>&1; then parse_git_branch; fi)'"..."
I installed JupyterLab with
pip3 install jupyterlab --user
Yet, when trying I try to launch it (jupyter lab), I get the following error:
Error executing Jupyter command 'lab': [Errno 2] No such file or directory
The JupyterLab installation guide on github says that: "If installing using pip install --user, you must add the user-level bin directory to your PATH environment variable in order to launch jupyter lab"
But I don't what that means, I greatly appreciate any help. I am using Ubuntu 18.04
As said by the guide itself you need to add the user-level bin directory to your PATH environment variable, in order to do so you need at first spot which is the bin folder where Jupyter lab has been installed, and after that you can add that path with a simple command:
export PATH=$PATH:/path/to/your/jupyterlab/bin/directory
and it's done. You can check if you added it by running this other command:
echo $PATH
And you should see the content of PATH variable.
This method though will just add that variable for the current shell, meaning that when you close the terminal you lose the change in the variable. In order to make it permanent you need to edit another file which is ~/.bashrc.
One thing though, it's really important that you just add this line to the file:
PATH=$PATH:/path/to/your/jupyterlab/bin/directory
without changing all the rest of the file if you don't know what you are doing.
To give you a recap on what to do to make it permanent open a new shell and type:
gedit ~/.bashrc
This will open the file where you need to add the "export PATH...etc" command right at the end of the file in a new line. Then save the changes and reboot, from now on you should be able to open Jupyter lab directly from a shell with the command:
Jupyter lab
I'm trying to open a .py file on git bash but it doesn't work.
I have tried to follow some instructions like running python <filename> but it doesn't work for me.
When I run
python python_basics
I expect it will open the .py file but it says it can't open file 'python_basics':
[Errno 2] No such file or directory
From this question, the problem may very well be caused by Git Bash itself.
I would recommend you try running your Python file from a different terminal (Command Prompt or PowerShell if you are using Windows), using the command suggested in the comments:
python python_basics.py
Thank you for your question, I am here to help you and who will see this question.
if you mean you want to open the file like when click on the file and open it
you can use this command
Start filename.py
but if you want to open the file inside the gitbash use this command
vim filename.py
and if you mean to run the file from gitbash you can use this command
python pythonFileName.py
Now if the above command did not work with you, and you are in the windows10 Pro platform you should go to
environment variable >> Then system variable >> then choose path >> then Edit >> and put the python path >> restart the terminal and run it again
Notice: All of the above I tried and used in windows10 pro.
Thanks,
Hope to help anyone,
First check the python version installed on your system.
by command-
python --version.
If not found
set
$ PATH=$PATH:/c/Python27/
Adapting the path will solve your problem.
When using the script addon for Atom it brings up:
Unable to run
/usr/bin/python3
Did you start Atom from the command line?
atom .
Is it in your PATH?
PATH: /usr/bin/python3:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Frameworks/Python.framework/Versions/3.7/bin:/usr/bin/python3:/usr/local/share/dotnet:/Library/Frameworks/Mono.framework/Versions/Current/Commands:~/.dotnet/tools
How do I get Atom to recognize Python 3?
I tried installing Python using Homebrew and it is installed to /usr/local/bin/python3 as well as using the Terminal to add all of the suggested path locations to /etc/paths.
You need to properly configure the script package to use a profile that points to the correct python3.
Open a Terminal and navigate to the directory containing your scripts.
$ pwd
/Users/cerberus/Scripts
Get the path to python3
If you installed it via Homebrew, then it should be at:
$ python3 -V
Python 3.7.3
$ which python3
/usr/local/bin/python3
You can also check that Homebrew already updated PATH to add /usr/local/bin, but unless you did something wrong with the Python installation, this part is unnecessary.
$ echo $PATH
.../usr/local/bin/:/...
Now, start Atom from the command line as explained in the package docs
Make sure to launch Atom from the console/terminal. This gives atom
all your useful environment variables. Additionally, make sure to run
it with the project path you need.
$ cd /path/to/scripts
$ atom .
OR
$ atom /path/to/scripts
Go to Packages > Command Palette > Toggle (or use CMD+SHIFT+P)
Select Script: Run Options
Input the path to your scripts and the path to the python3 command
NOTE: On my machine, just setting python3 also works. But if you are having problems with your python path, you can try to specify the full path (/usr/local/bin/python3) as shown.
Save the profile (ex. as "Python3")
Now, when you want to run your Python scripts, use the Script: Run with Profile command and then select the profile you just created.
That should work now.
My GUI script that is a PyQt5 file (.pyw extension) does work when running on my IDE with a build configuration that tells the compiler to run the script with python3:
And it also works when i tell to the regular terminal on Linux to run same script with python3 like this:
When runned with the default python (python2.7) on a regular terminal it tells: ImportError: No module named PyQt5.QtWidgets.
My code does it have these lines on the start to tell that is a python3 script like: #!/usr/bin/python3 or #!/usr/bin/env python3 (I have python3 installed).
When double clicked on the Linux Mint File Explorer the cursor turns crosshair and nothing happends, with the terminal option, same happends and a empty terminal shows. Im talking these options
I guess Linux Mint still runs the scripts with python2.7 even when I added the bash lines to tell
Someone knows why the lines:
#!/usr/bin/python3
#!/usr/bin/env python3
doesnt work when just double click?
I want to run the script from the Linux File Explorer without the need of an IDE or using the terminal.
Try chmod +x file.py and run it in terminal by using ./file.py also try lunching the file from a different path, like python3 ~/path/to/file.py and see if the error persists
