converting python program into executable

So now, I have a python program which I would like to convert into an executable(preferably a single file). Right now the target systems are only RedHat(and CentOS) and Debian(and Ubuntu).

First, I've tried the PyInstaller but after running it, it creates a .spec file and 2 folders called build and dist. I have no idea how to proceed from there.

Second, I tried the freeze.py which ships with python. I understand the usage is as follows:

python /path/to/freeze.py  /path/to/myfile.py

This throws an error ***Test Failed*** 2 failures and NameError: name 'testdata' is not defined

The full error is as follows:

**********************************************************************
File "/usr/lib/python2.6/site-packages/freeze.py", line 117, in __main__.freeze
Failed example:
    testdata = json.loads(
        gzip.open("testdata.json.gz", "r").read().decode()
    )
Exception raised:
    Traceback (most recent call last):
      File "/usr/lib64/python2.6/doctest.py", line 1253, in __run
        compileflags, 1) in test.globs
      File "<doctest __main__.freeze[3]>", line 2, in <module>
        gzip.open("testdata.json.gz", "r").read().decode()
      File "/usr/lib64/python2.6/gzip.py", line 33, in open
        return GzipFile(filename, mode, compresslevel)
      File "/usr/lib64/python2.6/gzip.py", line 79, in __init__
        fileobj = self.myfileobj = __builtin__.open(filename, mode or 'rb')
    IOError: [Errno 2] No such file or directory: 'testdata.json.gz'
**********************************************************************
File "/usr/lib/python2.6/site-packages/freeze.py", line 121, in __main__.freeze
Failed example:
    freeze(testdata) == freeze_fast(testdata)
Exception raised:
    Traceback (most recent call last):
      File "/usr/lib64/python2.6/doctest.py", line 1253, in __run
        compileflags, 1) in test.globs
      File "<doctest __main__.freeze[4]>", line 1, in <module>
        freeze(testdata) == freeze_fast(testdata)
    NameError: name 'testdata' is not defined
**********************************************************************
1 items had failures:
   2 of   8 in __main__.freeze
***Test Failed*** 2 failures.

I'd like some help to using either of the 2 (or any other tool which will help me achieve the same result).

Thanks.

Using the -F flag to pyinstaller.py will create a single, executable file and drop it into the dist/ directory.

pyinstaller.py --help shows a long list of options.

The pyinstaller-X.X/doc directory has the full manual in HTML and PDF.

You might wish to investigate Nuitka. It takes python source code and converts it in to C++ API calls. Then it compiles into an executable binary (ELF on Linux). It has been around for a few years now and supports a wide range of Python versions.

You will probably also get a performance improvement if you use it. Recommended.

If you want to make it executable, you have to chmod +x /path/to/script.py. This gives anybody permission to run the file. Then you can python /path/to/script.py.

You still need to start the command with python, that is ugly. If you add this line #!/usr/bin/env python to the first line of your script. This is callled a shebang or a hashbang. Then (still remember to chmod it) you can /path/to/script.py and it will execute.

If you are already in the directory of your script you can ./script.py. (still remember to chmod it and at a shebang)

If you still aren't satisfied, and you want to type in just the name of your script, you move the script into one of the folders on your path (which you can find by typing echo $PATH in shell, typically this is /usr/, /bin/, /usr/local/bin, or something like that). If you move your script into one of those folders, then you can just script.py. If you do this, I recommend you drop the .py extension, so you can just type in script. This will kind of make look like other unix shell commands (ls, grep, cat) at least in its invocation.

You can try using cython to turn it into a c executable
