Assumed you have multi python on local disk or usb driver, would like to show you how to setup portable dev tools.
1) portable python env
Instead of using virtualenv, I perfect portable instance, but we can do similar thing like virtualenv – setup own dev env, in fact all we need is just to setup python bin and Script at beginning of PATH.
dreamcloud> /usr/local/bin
$ cat mypy3 #!/bin/bash OLD_PATH="$PATH" PATH=/portable/PortablePython3.2.5.1/App:/portable/PortablePython3.2.5.1/App/Scripts:$PATH export OLD_PATH PATH export PS1='(portablepython3) \u> \w $ '
then source the mypy3
$ source mypy3 (portablepython3) dreamcloud> /usr/local/bin $ which -a python /portable/PortablePython3.2.5.1/App/python.exe /c/Python27/python.exe
undo the env change after finish:
$ cat /usr/local/bin/back #!/bin/bash export PATH=$OLD_PATH unset OLD_PATH export PS1='\u> \w $ '
2) install setuptools
this is python installation tool base, you can download ez_setup.py, install it using own python:
$ python ez_setup.py Downloading https://pypi.python.org/packages/source/s/setuptools/setuptools-7.0.zip Extracting in c:\users\xxx\appdata\local\temp\tmpw0vv6l Now working in c:\users\xxx\appdata\local\temp\tmpw0vv6l\setuptools-7.0 Installing Setuptoolsdreamcloud> /portable/PortablePython3.2.5.1/App/Scripts $ ls -ltr total 970 drwxr-xr-x 2 xxx Administrators 0 Nov 2 2013 distribute.egg-info drwxr-xr-x 2 xxx Administrators 0 Nov 2 2013 _markerlib drwxr-xr-x 3 xxx Administrators 0 Oct 18 11:02 tests drwxr-xr-x 4 xxx Administrators 0 Oct 18 11:02 setuptools drwxr-xr-x 5 xxx Administrators 0 Oct 18 11:02 docs -rwxr-xr-x 1 xxx Administrators 10476 Nov 9 08:55 ez_setup.py -rw-r--r-- 1 xxx Administrators 846758 Nov 9 08:56 setuptools-7.0.zip -rw-r--r-- 1 xxx Administrators 647 Nov 9 08:57 easy_install.exe.manifest -rwxr-xr-x 1 xxx Administrators 65536 Nov 9 08:57 easy_install.exe -rwxr-xr-x 1 xxx Administrators 370 Nov 9 08:57 easy_install-script.py -rw-r--r-- 1 xxx Administrators 651 Nov 9 08:57 easy_install-3.2.exe.manifest -rwxr-xr-x 1 xxx Administrators 65536 Nov 9 08:57 easy_install-3.2.exe -rwxr-xr-x 1 xxx Administrators 378 Nov 9 08:57 easy_install-3.2-script.py easy_install.exe is main tool you needed to install any python package. $ easy_install --help Global options: --verbose (-v) run verbosely (default) --quiet (-q) run quietly (turns verbosity off) --dry-run (-n) don't actually do anything --help (-h) show detailed help message Options for 'easy_install' command: --prefix installation prefix --zip-ok (-z) install package as a zipfile --multi-version (-m) make apps have to require() a version --upgrade (-U) force upgrade (searches PyPI for latest versions) --install-dir (-d) install package to DIR --script-dir (-s) install scripts to DIR --exclude-scripts (-x) Don't install scripts --always-copy (-a) Copy all needed packages to install dir --index-url (-i) base URL of Python Package Index --find-links (-f) additional URL(s) to search for packages --build-directory (-b) download/extract/build in DIR; keep the results --optimize (-O) also compile with optimization: -O1 for "python - O", -O2 for "python -OO", and -O0 to disable [default: -O0] --record filename in which to record list of installed files --always-unzip (-Z) don't install as a zipfile, no matter what --site-dirs (-S) list of directories where .pth files work --editable (-e) Install specified packages in editable form --no-deps (-N) don't install dependencies --allow-hosts (-H) pattern(s) that hostnames must match --local-snapshots-ok (-l) allow building eggs from local checkouts --version print version information and exit --no-find-links Don't load find-links defined in packages being installed --user install in user site-package 'C:\Users\xxx\AppData\Roaming\Python\Python32 \site-packages' usage: easy_install-script.py [options] requirement_or_url ... or: easy_install-script.py --help
3) pip installation
pip is a python package manager which based on setuptools. We have easy_install why still need pip? easy_install can install/upgrade/uninstall but cannot list local installed packages :)
$ easy_install pip F:\oldhorse\portableapps\PortablePython3.2.5.1\App\lib\site-packages\setuptools-7.0-py3.2.egg\setuptools\package_index.py:269: UserWarning: Unbuilt egg for distribute [unknown version] (f:\oldhorse\portableapps\portablepython3.2.5.1\app\scripts) F:\oldhorse\portableapps\PortablePython3.2.5.1\App\lib\site-packages\setuptools-7.0-py3.2.egg\setuptools\command\easy_install.py:315: UserWarning: Unbuilt egg for distribute [unknown version] (f:\oldhorse\portableapps\portablepython3.2.5.1\app\scripts) Searching for pip Reading https://pypi.python.org/simple/pip/ Best match: pip 1.5.6 Downloading https://pypi.python.org/packages/source/p/pip/pip-1.5.6.tar.gz#md5=01026f87978932060cc86c1dc527903e Processing pip-1.5.6.tar.gzInstalled f:\oldhorse\portableapps\portablepython3.2.5.1\app\lib\site-packages\pip-1.5.6-py3.2.egg Processing dependencies for pip Finished processing dependencies for pip $pip list Exception: Traceback (most recent call last): File "F:\oldhorse\portableapps\PortablePython3.2.5.1\App\lib\site-packages\pip-1.5.6-py3.2.egg\pip\_vendor\pkg_resources.py", line 2259, in version return self._version File "F:\oldhorse\portableapps\PortablePython3.2.5.1\App\lib\site-packages\pip-1.5.6-py3.2.egg\pip\_vendor\pkg_resources.py", line 2344, in __getattr__ raise AttributeError(attr) AttributeError: _version
remedy is simple but indirectly:
$ rm -r distribute.egg-info/ $ easy_install distribute $ pip list distribute (0.7.3) ipython (0.13.1) lxml (2.3) matplotlib (1.2.1) numpy (1.7.1) pandas (0.11.0) pip (1.5.6) pyodbc (3.0.2) pyreadline (2.0-dev1) pyserial-py3k (2.5) pywin32 (218) scipy (0.12.0) setuptools (7.0) wsgiref (0.1.2)
4) yolk installation
$ pip install yolk Downloading/unpacking yolk Running setup.py (path:c:\users\xxx\appdata\local\temp\pip_build_xxx\yolk\setup.py) egg_info for package yolk
the latest yolk release from pypi in fact not works with Python3, print/exception syntax still in Python2.
You have to download yolk develop release from github:
https://github.com/cakebread/yolk
then install it manually:
dreamcloud> /portable/PortablePython3.2.5.1/App/Scripts/yolk-develop $ python setup.py install $ yolk -l distribute - 0.7.3 - active ipython - 0.13.1 - active lxml - 2.3 - active matplotlib - 1.2.1 - active numpy - 1.7.1 - active pandas - 0.11.0 - active pip - 1.5.6 - active pyodbc - 3.0.2 - active pyreadline - 2.0-dev1 - active pywin32 - 218 - active scipy - 0.12.0 - active setuptools - 7.0 - active wsgiref - 0.1.2 - active development (f:\oldhorse\portableapps\portablepython3.2.5.1\app\lib) yolk - 0.4.3 - non-active yolk - 0.4.3 - non-active yolk - 0.4.3 - active yolk - 0.4.3 - active
