安装Python命令行脚本

Question

I am trying to understand how to install Python packages with command line scripts. What I mean by this is installing a package with eg pip install package and then be able to run package while in any directory, ie, that package should be on my path.

I am following this guide , which creates a minimal working example, and you install the package with pip install . .

There are two alternatives here, one with console_scripts in entry_points , and one with scripts and creating a bin folder and put an executable script in there. More detailed:

First method: scripts

Add a directory bin , in the same directory as the funniest package. So:

funniest/
    __init__.py
    text.py
bin/
    funniest-joke

The funniest-joke file is

#!/usr/bin/env python

import funniest
print(funniest.joke())

In setup.py , add scripts=['bin/funniest-joke'] as an argument in the setup function call.

Second method: console_scripts

Add a command_line.py file alongside text.py and __init__.py , which is

import funniest

def main():
    print funniest.joke()

In setup.py , add this as an argument to the setup function call:

entry_points={
    'console_scripts': [
        'funniest-joke = funniest.command_line:main'
    ],
},

The problem is that I can't get any of these to work. The packages install just fine, but I do not get an executable on my path, and it does not even seem to put anything in any /bin/ directory. There should be a funniest-joke on my path, but there is not.

For information: I am using a miniconda installed Python, which is at ~/miniconda3/ , so my pip , which I use to install the packages, is at ~/miniconda3/bin , and Python is also the one at ~/miniconda3/bin .

The package ( funniest ) is installed into /miniconda3/lib/python3.6/site-packages/funniest .

My path contains the following directories.

/bin/
/usr/local/bin/python
/Users/USERNAME/miniconda3/bin
/usr/local/bin
/usr/bin

Is anyone able to help me?

Answer 1

When you enter in the terminal:
which python

The example will show you the location of the default python you are using.
By what you have said your result will probably be.
/Users/USERNAME/miniconda3/bin/python

That being said, if you enter:
which <executable>
for any executable, the terminal will show you where it is installed.
I hope that helps.

Answer 2

you don't need to follow the path to install the package in python. But you need to follow this way 1. first install python on pc 2. simple Open command prompt then type pip install (---python package name----) 3. then press Enter button but make sure internet is available.
