从 linux bash 脚本激活 python 虚拟环境

Question

I am writing a bash script in linux that creates and activates a Python venv and then installs from a requirements.txt. Like this

python3 -m venv ~/myvenv/env
source ~/myvenv/env/bin/activate
cp requirements.txt ~/myvenv/env/requirements.txt
pip3 install -r ~/myvenv/env/requirements.txt

This doesn't work for me. It seems to create the myvenv directory but then doesnt switch in and run the requirements.txt file.

Is there a different way to activate it with source from within a bash script?

Answer 1

When you run script your shell spawns new process, activates it and then dies. That's why when you get back into your shell you see unactivated one.

you can run your script just using source command. source command will load it into your active shell.

source script.sh
