While there might be subtle differences between unix and windows, the straight-up answer is: you can use PYTHONPATH environment variable to let python know where to look for libraries.
However, if you use venv, I'd recommend activating it first, or calling the relevant binary instead of setting the environment variable.
Consider this scenario: you have a venv at /tmp/so_demo/venv, and you try to run this file:
$ cat /tmp/so_demo/myscript.py
import requests
print("great success!")
Running the system python interpreter will not find the requests module, and will yield the following error:
$ python3 /tmp/so_demo/myscript.py
Traceback (most recent call last):
File "/tmp/so_demo/myscript.py", line 1, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
As I have installed requests in the venv, if I provide the path to python, it will know where to look:
$ PYTHONPATH='/tmp/so_demo/venv/lib/python3.8/site-packages/' python3 /tmp/so_demo/myscript.py
great success!
but using the binary inside the venv is better, as you don't need to be familiar with the internal venv directory paths, and is much more portable (notice that the path I provided earlier depicts the minor version):
$ /tmp/so_demo/venv/bin/python /tmp/so_demo/myscript.py
great success!
I need to add the win_unicode_console module to my usercustomize.py file, as described by the documentation.
I've discovered my user site packages directory with:
>>> import site
>>> site.getusersitepackages()
'C:\\Users\\my name\\AppData\\Roaming\\Python\\Python35\\site-packages'
I haven't been able to get to this directory using any method. I've tried using pushd instead of cd to emulate a network drive, and I've also tried getting there using run. No matter what I do in python, or in cmd terminal. I get the response The network path was not found.
Here is an example of one I've tried in cmd:
C:\>pushd \\Users\\my name\\AppData\\Roaming\\Python\\Python35\\site-packages
The network path was not found.
What am I doing wrong, or what could be wrong with the path?
DOS style backslashes don't need to be escaped within the Windows console (else they may have used forward slashes way back when!).
Follow these steps to manually create usercustomize.py:
Start->Run:cmd
Make sure you're on the C: drive
c:
Create the directory. mkdir creates the missing parents. Obviously, change "my name" as appropriate.
mkdir C:\Users\my name\AppData\Roaming\Python\Python35\site-packages
Create usercustomize.py:
notepad C:\Users\my name\AppData\Roaming\Python\Python35\site-packages\usercustomize.py
Click "yes" to create your file.
Edit as appropriate
Or use the following script to have Python do it for you:
import site
import os
import os.path
import io
user_site_dir = site.getusersitepackages()
user_customize_filename = os.path.join(user_site_dir, 'usercustomize.py')
win_unicode_console_text = u"""

win_unicode_console.enable()

if not win_unicode_console_text in existing_text:

user_customize_file.write(win_unicode_console_text)
print("win_unicode_console added to {filename}".format(filename=user_customize_filename))

I want to build a cross-platform application ,I used a windows API called SHOpenFolderAndSelectItems(). Although I found example called it by pywin32,but pywin32 is not available on Linux , I don't want to call a Windows API on linux,just don't want to make another code version for Linux,so I wonder how to access it by ctypes? yes,this API cannot be called on Linux ,I just want to make it silent in the code so that I can freeze the Python scripts into executables by cx_Freeze without pywin32 module-missing error happend .

As you can see, both OS X and Windows 7 are referring to something similar here. Please help.
i have found a solution
in api.py
From
_thisdir = os.path.split(__file__)[0]
To
_thisdir = 'C:\Python27\Lib\site-packages\docx'
Or whatever your docx file is
What's going on (at least for py2exe) is something similar to this question.
The documentation on data_files is here.
What you basically have to do is change
setup(options = {'py2exe': OPTIONS},zipfile = None,windows=[{'script': '%s.py' %(main_script)}])
to
data_files = [
('template', 'D:/Program Files (x86)/Python27/Lib/site-packages/docx-template/*'),
]
setup(
options={'py2exe': OPTIONS},
zipfile=None,
windows=[{'script': '%s.py' %(main_script)}],
data_files=data_files
)
The exact place where the template files are may be wrong above, so you might need to adjust it.
But there may be several other sets of data_files you need to include. You may want to go about retrieving them programatically with an os.listdir or os.walk type of command.
As mentioned in the other post, you will also have to change
bundle_parameter=1
to
bundle_parameter=2
at the top of the file.
You can solve the entire problem by using this API which is based in python-docx. The advantage of the API is that this one doesnt have the savedoc function so you will not have any other AssertionError.
For the WindowsError: [Error 3] The system cannot find the path specified: 'D:\\docx_example\\docx_example.exe\\template' error you need to edit the api.py file of docx egg folder which is located in the Python folder of the system (in my computer: C:\Python27\Lib\site-packages\python_docx-0.3.0a5-py2.7.egg\docx)
Changing this:
_thisdir = os.path.split(__file__)[0]
_default_docx_path = os.path.join(_thisdir, 'templates', 'default.docx')
To this:
thisdir = os.getcwd()
_default_docx_path = os.path.join(thisdir, 'templates', 'default.docx')
The first one was taking the actual running program and adding it to the path to locate the templates folder.
C:\myfiles\myprogram.exe\templates\default.docx
The solution takes only the path, not the running program.
C:\myfiles\templates\default.docx
Hope it helps!
Instead of changing some library file, I find it easier and cleaner to tell python-docx explicitly where to look for the template, i.e.:
document = Document('whatever/path/you/choose/to/some.docx')
This effectively solves the py2exe and docx path problem.
I am trying to execute this script by Ned Batchelder to switch .py file association between my two Python installations on Windows. This Python script uses the _winreg module (winreg in Python 3.x) to edit certain Registry values (the path and value pairs modified can be seen in the todo list in the script).
I execute this script as follows:
> SwitchPy.py "C:\Program Files\Python26"
I am getting the following error:
Traceback (most recent call last):
File "C:\Users\SuperUser\SwitchPy.py", line 30, in <module>
key = reg.OpenKey(classes_root, path, 0, reg.KEY_SET_VALUE)
WindowsError: [Error 5] Access is denied
I guessed that it could be something to do with account permissions. But, note that:
The account used above is part of the Administrators group and has admin privileges.
With the above account I can execute regedit.exe and manually set the values listed in the script without facing any permissions or access problems.
I am using Windows 7 and am part of a domain. Could any of this have something to do with this problem?
Does anyone have any clue about this error? How do I make this script run?
When I tried that one, I got "Path not found" error on Python.CompiledFile.
I checked it on my registry, it does not exist, not Windows 7 though.
So, I removed those lines of Python.CompiledFile and its running fine here, or
You could put try: except: On OpenKey and SetValue, not good idea though.
I was able to run the script by opening a command prompt using the "Run as Administrator".
It appears that you can only maintain HKEY_LOCAL_MACHINE entries if you run the script with elevated authorities.
Some of the HKEY_CLASSES_ROOT entries come from HKEY_LOCAL_MACHINE according to this MSDN link:
The HKEY_CLASSES_ROOT subtree is a view formed by merging HKEY_CURRENT_USER\Software\Classes and HKEY_LOCAL_MACHINE\Software\Classes
I updated the script to include the suggested try/except in addition to a few print statements for extra feedback.
Here is how I updated the script:
""" Change the .py file extension to point to a different
Python installation.
