I’m learning Python on my own and have been stuck for two days trying to get
modules I created into site-packages. As a trial step, we were asked to change
directly into the folder containing our modules. I typed “cd mymodules” per
instructions, but got this error message: “-bash: cd: mymodules: No such file
or directory.” I saved mymodules to my documents. What is going wrong here?
When I tried to create a distribution file, I typed “192:~ TamaraB$ mymodules$
python3 setup.py sdist.” I got this error message: “-bash: mymodules$: command
not found.” What should I do?

“We'll need some more information about the computer you are using: what OS
are you using (Mac, Linux, Windows, something else), what shell are you
using, perhaps a file listing of your home directory. “
I’m using Terminal in Mac Sierra (10.12.6).
Cool.
“(I'm not sure what the 192 part means. Does that increase each time you type a
command?) “
I'm new to Terminal, but that 192 looked weird to me too. It doesn’t increase,
just stays at 192. There is also a thin gray left bracket in front of the “192”
which didn’t copy into my email. Is there some way to restore the default
prompt in Terminal (and what is the default prompt)?
On a Mac, it tends to be like this: "{hostname}:~ {username}$ " where
{hostname} is your Mac's name and {username} is your login name; that is called
the "shell prompt", and "the shell" is the command line interpreter running the
commands you type. On a Mac, this is usually bash, a UNIX Bourne shell.
There is a secondary prompt like this "> ". That indicates that you're typing a
compond command, or at least that the shell believes you're typing a compond
command, which is just a command which extends to more than one line. The
common way to confuse the shell about this is to forget to close a quote - the
shell expects that string to continue until it sees a closing quote.
You can leave the secondary prompt by typing Control-C (often denoted "^C").
That will cancel the incomplete command and get you back to a clean empty
primary prompt.
Note that if you start some interactive command, such as the interactive Python
interpreter, you will then be dealing with _its_ prompts until you leave that
command.
Back to my problem. Your email helped me get into the mymodules folder, but I’m
still stuck at the next step of the exercise, which is to get the module I
created into site-packages. mymodules contains three files: the module we
created, a setup file (setup.py), and a readme file. The line of text we were
instructed to type into our terminal was: “python3 setup.py sdist.” In
response, I got this error message:
“/Library/Frameworks/Python.framework/Versions/3.6/Resources/Python.app/Contents/MacOS/Python:
can't open file 'setup.py': [Errno 2] No such file or directory”.
Why is this not working for me?
I would expect that your shell is not actually in the "mymodules" directory
when you typed "python3 setup.py sdist". Usually your shell prompt includes the
current working directory (the "~" in my example above, which is your home
directory), which is a useful contextual clue.
You can also find out your current working directory by running the "pwd"
command (the "print working directory" command).
The "ls" (list) command without arguments will list what is in the current
directory, so you can now check (a) whether you're where you thought you were,
and (b) what is in the current directory (in case it doesn't contain what you
expected).
The "ls -la" command will provide a longer and more detailed listing too.
Let us know what you find out.
