Trying to install easy_install (IRONIC) and it is not wanting to cooperate with me.
I am running the following command in terminal with python2.7
curl https://bootstrap.pypa.io/ez_setup.py -o - | python
returns me -->
-bash: https://bootstrap.pypa.io/ez_setup.py: No such file or directory
is it a simple fix?
This should work:
curl https://bootstrap.pypa.io/ez_setup.py -s | python
Unless redirected otherwise, cURL will output the received body to STDOUT, so you do not have to pass it -o - (which really should not do anything according to the docs). You should pass it -s in order to suppress the progress meter and any errors. Then pipe it directly into python. Given no other arguments, python will determine STDIN as the source of the script to execute.

If I use the following command in the Git Bash, it works fine. The Output from the curl are write into the file output.txt
curl -k --silent "https://gitlab.myurl.com/api/v4/groups?page=1&per_page=1&simple=yes&private_token=mytoken&all?page=1&per_page=1" > output.txt
Python Code:
import subprocess, shlex
command = shlex.split("curl -k --silent https://gitlab.myurl.com/api/v4/groups?page=1&per_page=1&simple=yes&private_token=mytoken&all?page=1&per_page=1 > output.txt")
subprocess.Popen(command)
The Python code write nothing in my file "output.txt".
How can I write in the output.txt or get the Output direct in Python?
You cannot use redirection directly with subprocess, because it is a shell feature. Use check_output:
import subprocess
command = ["curl", "-k", "--silent", "https://gitlab.myurl.com/api/v4/groups?page=1&per_page=1&simple=yes&private_token=mytoken&all?page=1&per_page=1"]
output = subprocess.check_output(command)
You could use the command in another way in order to write to output.txt:
curl -k --silent "https://gitlab.myurl.com/api/v4/groups?page=1&per_page=1&simple=yes&private_token=mytoken&all?page=1&per_page=1" --output output.txt
Also you should consider that output.txt might not be saved in the directory you expect so I would also advice you to name output.txt in another way, a unique one, then update the locate linux command database (see updatedb command) and then search the file with locate.
PS: all this make sense when you need the writing to output.txt (your question accepts this situation too, so I hope it helps)
I am trying to run python code that I pull directly from Github raw URL using the Python interpreter. The goal is never having to keep the code stored on file system and run it directly from github.
SO far I am able to get the raw code from github using the curl command but since it is a multi-line code, I get the error that python cannot find the file.
python 'curl https://github.url/raw/path-to-code'
python: can't open file 'curl https://github.url/raw/path-to-code': [Errno
2] No such file or directory
How do I pass a multi-line code block to the Python interpreter without having to write another .py file (which would defeat the purpose of this exercise)?
You need to pipe the code you get from cURL to the Python interpreter, something like:
curl https://github.url/raw/path-to-code | python -
UPDATE: cURL prints download stats to STDERR, if you want it silenced you can use the -s modifier when calling it:
curl -s https://github.url/raw/path-to-code | python -
There is no way to do this via Python interpreter, without first retrieving the script then passing it to the interpreter.
The currant Python command line arguments can be accessed with --help argument:
usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Options and arguments (and corresponding environment variables):
-b : issue warnings about str(bytes_instance), str(bytearray_instance)
and comparing bytes/bytearray with str. (-bb: issue errors)
-B : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x
-c cmd : program passed in as string (terminates option list)
-d : debug output from parser; also PYTHONDEBUG=x
-E : ignore PYTHON* environment variables (such as PYTHONPATH)
-h : print this help message and exit (also --help)
-i : inspect interactively after running script; forces a prompt even
if stdin does not appear to be a terminal; also PYTHONINSPECT=x
-I : isolate Python from the user's environment (implies -E and -s)
-m mod : run library module as a script (terminates option list)
-O : optimize generated bytecode slightly; also PYTHONOPTIMIZE=x
-OO : remove doc-strings in addition to the -O optimizations
-q : don't print version and copyright messages on interactive startup
-s : don't add user site directory to sys.path; also PYTHONNOUSERSITE
-S : don't imply 'import site' on initialization
-u : force the binary I/O layers of stdout and stderr to be unbuffered;
stdin is always buffered; text I/O layer will be line-buffered;
also PYTHONUNBUFFERED=x
-v : verbose (trace import statements); also PYTHONVERBOSE=x
can be supplied multiple times to increase verbosity
-V : print the Python version number and exit (also --version)
when given twice, print more information about the build
-W arg : warning control; arg is action:message:category:module:lineno
also PYTHONWARNINGS=arg
-x : skip first line of source, allowing use of non-Unix forms of #!cmd
-X opt : set implementation-specific option
file : program read from script file
- : program read from stdin (default; interactive mode if a tty)
arg ...: arguments passed to program in sys.argv[1:]
If you want it all on one line then use | to set multiple commands
curl https://github.url/raw/path-to-code --output some.file|python some.file
I used grep command from shell and it gave the result I wanted but when I run from my python script using os.popen it said
grep: SUMMARY:: No such file or directory
Normal grep command:
grep -A 12 -i "LOGBOOK SUMMARY:" my_folder/logbook.log
Python script
command="grep -A 12 -i LOGBOOK SUMMARY: my_folder/logbook.log"
result=os.popen(command)
Normal grep command gave the result I wanted.
2nd one said no such file or directory
You need to enclose the search pattern within quotes:
command="grep -A 12 -i 'LOGBOOK SUMMARY:' my_folder/logbook.log"
How to diagnose such problems? Start from the error message:
grep: SUMMARY:: No such file or directory
This error message tells that grep could not find a file named SUMMARY:.
The right question to ask is, why is grep looking for a file named SUMMARY:?
And the answer is that on the command line you executed,
somehow SUMMARY: is considered a filename:
command="grep -A 12 -i LOGBOOK SUMMARY: my_folder/logbook.log"
Of course! That's what would happen if you executed that command in the shell:
grep -A 12 -i LOGBOOK SUMMARY: my_folder/logbook.log
Here, the shell will split the command line on spaces,
and pass to grep 3 arguments, LOGBOOK, SUMMARY: and my_folder/logbook.log.
The first argument, LOGBOOK is used as the pattern to search for,
and all remaining arguments are taken as filenames to search in.
I thought I'd post this here because hours of googling ended up fruitless. I have an obj file and I'm trying to use the python script included with three.js to export it for use in three.js however I have never used python before and don't know what I'm doing.
These have been my steps so far:
I've opened up the Python GUI, opened up convert_obj_three.py, clicked run -> run module, and then I get this:
======= RESTART: C:\three.js\utils\converters\obj\convert_obj_three.py =======
Usage: convert_obj_three.py -i filename.obj -o filename.js [-m morphfiles*.obj] [-c morphcolors*.obj] [-a center|top|bottom] [-s flat|smooth] [-t binary|ascii] [-d invert|normal]
When I try typing in something like convert_obj_three.py -i test.obj -o test.js I get an SyntaxError: invalid syntax error.
test.obj is in the same folder as convert_obj_three.py however that does not seem to be the issue as no matter what I type I seem to get a syntax error...
Run the command:
convert_obj_three.py -i test.obj -o test.js
at a command prompt. On Windows, Python will have to be in your path for this to work, that's an option in the installer (at least in 2.7) right at the bottom of the list of options, IME sometimes not visible - very easy to miss - so scroll down to find it.
Deployment by using Python throws error:
I used Python code ( its your deploy.py) to deploy our proxy (our company proxy) into apigee platform. i read http://apigee.com/docs/api-services/content/deploying-proxies-command-line
but it throws error when i run "python api-platform-samples-master/tools/deploy.py -n apikey -u "yusuf.karatoprak#mobgen.com:Welcome#2014" -o yusufkaratoprak123 -e test -p / -d sample-proxies"
i would like to solve this situation. i added to python code it is not working. it throws me Error: name 'ZipFile' is not defined
The -d flag value needs to point to the directory that contains the /apiproxy directory for the sample you want to deploy. (In your command above, it appears that you are pointing at /sample-proxies, rather than, for example, /sample-proxies/apikey
Try using the deploy scripts. There is one in each sample proxy directory. There's a also a script, /setup/deploy_all.sh if you want to deploy all sample proxies.
Make sure you update /setup/setenv.sh before running the deploy scripts.
The error is in how you are calling it from the command line. You have a space in one of the parameters you pass in, which needs to be put inside of quotes. Turn -u yusuf karatoprak:123 into -u "yusuf karatoprak:123"
Fixed command line call:
python api-platform-samples-master/tools/deploy.py -n weatherapi -u "yusuf karatoprak:123" -o yk123 -e test -p / -d simpleProxy
