pip安装后找不到包

Question

I've published a module to PyPi using Flit: a2d_diary (I've checked that the tar.gz contains all the scripts).

Then, I tried to install it in a virtual env in Windows and Linux using pip install a2d_diary and although it works and all dependencies are installed, if I try to run a2d_diary in a terminal (with the venv activate) it does not find my package.

Is this a problem with Flit, PyPi or am I missing something in the main script? The source code is here

Thanks!

The file a2d_diary.py is installed, but it won't be accessible via running $ ad2_diary.py from your terminal. These are the package files that were installed:

$ pip show -f a2d_diary
Name: a2d-diary
Version: 0.1
Summary: A2D-Diary web app. Create and encode paper diaries

  a2d_diary-0.1.dist-info/WHEEL
  a2d_diary.py

If you want the script to be executable after the installation, you have to declare it as such in the package setup file (btw, I don't see any setup.py in your repository - did you commit it?). Example setup.py :

from setuptools import setup, find_packages

setup(
    name='a2d_diary',
    version='0.1',
    packages=find_packages(where='src'),
    package_dir={
        '': 'src',
    },
    scripts=['src/a2d_diary.py'],
)

Another thing you will need in order to make your a2d_diary.py script executable is the shebang line (works for Unix, no idea what to do on Windows since I don't do Windows at all): first line in a2d_diary.py should be

#!/usr/bin/env python

if your script can be run with any version of Python or

#!/usr/bin/env python3

for Python 3 specifically or

#!/usr/bin/env python2

for Python 2 specifically.

Now, if you build a wheel or source tar and install it, you will be able to run the script via

$ a2d_diary.py
