Python Django requirements.txt

Question

I have a requirements.txt file containing all my dependencies but it is not processed correctly :

After a pip install -r requirements.txt, I get the following pip freeze :

argparse==1.2.1
wsgiref==0.1.2

But when I do a pip install of :

numpy==1.6.2
Django==1.4.2
django-tastypie==0.9.14
pyes==0.19.1

And then run my pip install -r requirements.txt . Then it works.

Here is what my requirements.txt contains :

numpy==1.6.2
Django==1.4.2
django-tastypie==0.9.14
urllib3==1.5
pyes==0.19.1
BeautifulSoup==3.2.1

boto==2.8.0
lxml==3.1.0
pyelasticsearch==0.4.1
django-tastypie-elasticsearch==0.1.0

Would anyone have a solution ?

Answer 1

I tried this out and the problem is with django-tastypie-elasticsearch. There is a known issue, whereby installation with pip fails if Django hasn't been installed yet. Here is the issue report:

Looks like django-tastypie-elastic has only two contributors, so you're probably on your own. The good news is that it wasn't your fault!

On mac:

To get your already installed dependencies

pip3 freeze > requirements.txt

from: Automatically create requirements.txt

---

Then if you want to install them, and you are using a virtual environment

pip3 install -r requirements.txt

from: How can I install packages using pip according to the requirements.txt file from a local directory?

---

If you want to update them

I just know how to do it with pip-review. https://pypi.org/project/pip-review/#description

pip3 install pip-review or pip install pip-review

then pip-review --local --auto

from: How to upgrade all Python packages with pip

The "https://codeload.github.com/toastdriven/django-haystack/zip/master#egg=django-haystack" line is not a valid pip requirement. It should read "-e git+https://codeload.github.com/toastdriven/django-haystack/zip/master#egg=django-haystack"
