通过bash脚本和pip在虚拟环境中安装python包

Question

To clarify I have read these questions already:

How to source virtualenv activate in a Bash script

How to activate python virtual environment by shell script

Activating virtualenv in Bash script not working

Bash: How _best_ to include other scripts?

My goal is to create a script that will automate the process of installing several (roughly 27) python packages via pip in a virtual environment using (preferably) a bash script.

So far in bash scripts I have tried:

source env/bin/activate
pip install numpy Scipy ez_setup 

As well as

activate() {
. ../.env/bin/activate
}

activate
pip install numpy Scipy ez_setup 

Neither of which works. What is the best way to approach this problem given it must be executable as part of a larger bash (or python) script?

Answer 1

Update: So I figured out my problem. The solution for me is to force the script to pull from the correct pip directory with

/env/bin/pip install numpy Scipy ez_setup

The second part is to break down the install instructions into each line because the registries were not being updated properly.
