How do you install pip packages? I think I’ve gone through all the flags for pip with zero success
```auto
matrix:
include:
- os: linux
dist: trusty
sudo: required
services:
- docker
#language: node_js
#node_js:
# - "8"
language: python
python:
- "3.6"
before_install:
# install nsenter which is required for port forwarding
#- sudo -H pip3 install --upgrade --ignore-installed --user --install-option="--prefix=$HELM_INSTALL_DIR" jinja2
#- sudo -H pip3 install --upgrade --ignore-installed --user jinja2
#- pip install jinja2
- pip install --upgrade --ignore-installed --install-option="--prefix=$HELM_INSTALL_DIR" jinja2
script:
- export PATH=/home/travis/.local/bin:$PATH
- echo "export PATH=/home/travis/.local/bin:$PATH" >> /home/travis/.bashrc
- env
- which jinja2
```

Just pip install should be fine. Travis CI creates and activates a virtualenv before execution of your steps.
Another question would be is jinja2 shipped with a script now? Never heard of it…

ah you are correct, I was looking for jinja2-cli! My mistake entirely.
I will add that I had to add the --user or the prefix, or use sudo

It is strongly discouraged to use sudo. You’ll mess up your system python installation this way.

So do use --user but not if you specified `language: python`
```auto
matrix:
include:
- os: linux
dist: trusty
sudo: required
services:
- docker
language: python
python:
- "3.6"
before_install:
- pip install --user jinja2-cli
script:
- which jinja2
```
results in:
```auto
pip install --user jinja2-cli
Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
The command "pip install --user jinja2-cli" failed and exited with 1 during .
```
however if you use something else like node:
```auto
matrix:
include:
- os: linux
dist: trusty
sudo: required
language: node_js
node_js:
- "8"
before_install:
- pip install --user jinja2-cli
script:
- which jinja2
```
so use sudo only if you want to break your system python in this ephemeral system that is about to be deleted, don’t use --user with pip if your language is speciffied as python, but feel free elsewhere.
I’m glad this is perfectly clear 😉

In case you’re still wondering why:
- Python installations have 2 “site packages”, locations where they install packages. The default one and the user one.
- When you specify the python language Travis sets up what’s known as a `virtual environment`. Since those are isolated environments they have their own site packages but they have just the default one, which is why `--user` will fail. (You’re already specifying an environment by being inside a virtualenv, `--user` is conceptually `n/a` here)
- When you don’t specify a python language you’re installing the packages to the system pythons which do have a user site packages
Never use sudo to pip install though:
- You expose yourself to arbitrary code execution through a variety of package manager attacks
- The installed files might not be readable to your regular user
- You might overwrite packages that your system python relied on and mess up your linux distro
If you don’t know which situation you’re in you could alwys try a user install and if it errors chain it to a normal install:
> pip install … --user || pip install …
