Pypi installer and web server
So I thought it would be cool to have a package installer, and have it be callable via a get request from a browser. The following gist is the code I have for the installer:
It can be used like:
from Pypi import Installer Installer('Flask', '0.9').install()
It will attempt to download the package (no dependencies though) via Pypi. Keep in mind that Pypi is case sensitive, so make sure the first argument is correct (for instance flask is 'Flask' but bottle is 'bottle'). If you are unsure, check the download URL on Pypi's site.
It also currently only checks for two types of sources in the tarball. Either a directory with the package name (lowercase) or a single python file with the package name (like bottle.py). This seems to have covered all the packages I have attempted (but maybe not everything).
Lastly, keep in mind, even though you can install a package, doesn't mean it will work.
Next, to create a web server, first use the installer to install Flask, Werkzeug, and Jinja2:
from Pypi import Installer Installer('Flask', '0.9').install() Installer('Werkzeug', '0.8.3').install() Installer('Jinja2', '2.6').install()
Then download this gist which has a demo Flask Server:
After running this Flask Server, it will tell you your IP address. In a browser, you can now install packages on your device by going to 'http://IP_ADDRESS:5000/install?package=Flask&version=0.9' while it is running, replacing of course the package and version you want.
The server is more of a demo, it would probably be better off serving some form instead of using the URL. Also, note that Flask's debug mode does not appear to work, as it complains it is not running on the main thread.
Let me know if you improve on anything!
Hello, I would ask if new packages installed with Pypi will be exported to xcodeproject for ios app final build to appstore. Thanks.
Sorry it took so long to get back to all of you. Didn't realize this got any responses.
@tturchi: I looked at MySQL-python. There are two reasons why it doesn't work. 1.) The latest version (1.2.4) uses a zip file rather than a tar.gz. The script assumes a tar file, so I need to make this script more flexible. 2.) Version 1.2.3, which uses a tar file, doesn't have the normally named source file/folder inside it. Since it doesn't see what it expects, it doesn't copy it. I haven't figured out the best way to "discover" all the sources within a Pypi module properly yet.
@Filippoclaudi: As for a Remove function, I can easily add that. Although, why not just use Pythonista's delete file/folder from its main menu?
@acescon: This script doesn't "install" pypi packages in the true sense of the word. It just does its best to extract the source files out of Pypi tar files and put them in the main directory for you to be able to import. In other words, it puts the source files in the same area you write your own files. Pythonista doesn't know that you didn't right them. So, if you can import your own code and it works, you should be able to import Pypi sources and have it work.
Great work Cicucci! I look forward to any updates with regards to handling zip files. I, too, am trying to use this to install MySQL-python.
@Tizzy StaSh - https://github.com/ywangd/stash will have pip in 3.0 access to pypi and a package manager.. It's currently in the dev branch. Hanbdles .zip, bz2, gz and will keep track of installed packages.
Should pypi.py be updated to use Pythonista's
@briarfox I use gitrepo to download gits and I was wondering if there is an easy way to download the dev branch of, for example, stash?
@ihf I am unfamiliar with git repo. You should be able to change the branch and grab the zip. You could use current stash to download and un archive the Dev.
I don't believe gitrepo supports branches, but if could be wrong.
You would have to modify
repolinkto point to dev.zip in this case.
You could also use
Which supports branches (simply copy the url after switching branches)
Or, in the case of stash, you could download master, then search for
And change to
(This is inside the
selfupdatefrom within stash.
So I was able to download the repo from https://github.com/farcepest/MySQLdb1 using Jon's GitHubGet script, but I'm not sure how to proceed to make it functional...importing MySQLdb still says no such module found. Do I move the whole folder into site-packages?
Thanks for all your help everyone!
Yes, you can move the MySQLdb folder (the one that contains an init.py) into site-packages.
I moved the folder MySQLdb (from inside MySQLdb1-master folder) containing init.py into site-packages. It now says " no module called _mysql"
@Tizzy Are you dead set on mysql? I've fell in love with mongodb with pymongo.
MySQL appears to be written partly in c. So no go on ios.
@briarfox I'm not dead set on it, but was just hoping to utilize existing infrastructure that I already have in place.
@JonB what about this connector made specifically for pythonista: https://github.com/tommasoturchi/mysql-connector-pythonista?files=1
Also It seems to lack an init.py...
This guy seems to have gotten it to work, but his instructions are not explicit enough for me to follow... http://omz-forums.appspot.com/pythonista/post/6201194041049088
It appears that the repo you pointed to basically implement the instructions already. You should be able to simply copy the files directly into site-packages, without any folder. Or, download into a folder, in which case you will need to sys.path.insert(1,abspath_to_mysqldb_folder) before importing msqldb.
You could also try grabbing stash (dev branch), and run
pip install mysql-connector-python. It seems like a lot of what was done in that github repo was because pythonista early versions did not have site-packages... There is no obvious reason the pypi package wouldn't work now, though I haven't tried.
To get the dev branch of Stash, simply set
SELFUPDATE_BRANCH=dev. This can be set in the
.stashrcfile, the resource file to stash that is located under stash's installation root (just create the file if not exist).
To install StaSh in the first place, you can either clone the repo or try single file gist installation script @ https://gist.github.com/ywangd/7fbb2c1aa17e8734defd
NOTE: If you do not have an utility to help you read/write dot files, e.g.
.stashrc, stash is also here to help. Simply follow these steps from within stash:
selfupdateto get the master branch release
edit -t .stashrc
- Now you can edit the file as a temporary file in Pythonista's builtin editor.
- Once you are done with the file, swipe right to reveal StaSh prompt, enter
Yto save the changes.
Please check StaSh GitHub repo for more details.
In fact, a very easy way to get the dev branch from within StaSh is to run the following one-line command (without editing any dot files):
A bit more explanations on it how works:
SELFUPDATE_BRANCHis an environment variable to the shell and has default value of
selfupdateby default grab the master branch.
- Like any other shells, environment variable can be set as
- The above command temporarily override the default value and make
selfupdategrab the dev branch.
