In my app, I've the pubspec.yaml file as:
name: server
dependencies:
oracledart: any
and after running pub get, I got the folder "packages" updated correctly.
I wanted to create sub folders for testing my functions individually, so I created folder: test/boms.dart, which is:
import 'dart:async';
import 'package:oracledart/oracledart.dart';
void main() {
...
}
but once running it, I got this error msg:
Unhandled exception:
Uncaught Error: FileSystemException: Cannot open file, path = 'G:\app\bin\test\packages\oracledart\oracledart.dart' (OS Error: The system cannot find the path specified.
Do I need to copy the 'packages' folder to each sub folder have the function "main", or there is another way to connect it!
At least for top-level folders the packages link should be created automatically. Try run pub get or pub upgrade or create the test folder from within DartEditor (I don't know what creates the symlinks but usually they are created automatically in top-level folders as far as I remember). In subfolders of top-level folders like bin, test, ... I always had to create them manually by creating a new symlink to the packages link in the package root.
In Linux like:
ln -s ../packages/ packages
don't know how to in Windows.
I think the DART team, should make symlinks auto generation in sub folders of the "bin" folder, same as the case of the sub folders of the "web" folder.
anyhow, to create them manually in Windows 7, I found it make as below:
1. run CMD as admin
2. mklink /D myApp\bin\test\packages myApp\packages [D for directory, not drive]
I found how to make symlinks in windows here
another full detailed way is mentioned here

I want to compile uic to PySide6 but I don't find how to install pyside6-uic tool. Where can I install pyside6-uic? I downloaded PySide6 but command pyside6-uic doesn't work.
There is a reference here in the title:
https://doc.qt.io/qtforpython/tutorials/basictutorial/uifiles.html#using-ui-files-from-designer-or-qtcreator-with-quiloader-and-pyside6-uic
Step 1. If you installed PySide6
a. In a venv then go to your venv's folder.
b. Globally then go to your python installation folder.
Step 2. Go to Lib then site-packages then PySide6.
Step 3. Copy uic.exe ( or uic if the file extension are hidden) create a folder called bin and paste what you've copied inside it.
To compile ui files from:
QtDesigner: From the top menu select Form -> View Python Code... then click on the save icon (floppy disk) from the newly opened window.
Command Prompt: pyside6-uic.exe mainwindow.ui > ui_mainwindow.py
PowerShell: pyside6-uic.exe mainwindow.ui -o ui_mainwindow.py
If you using virtual environment, when you install pyside6 with pip in the virtual environment there is a folder named Scripts there is the pyside6-uic.exe tool.
if you have install pyside6 globally in your system and you use visual studio code you can use the extension PySide2-vsc then when you installed you can go to preferences > settings and search the PySide2-vsc extension settings then look for the "Command to compile a .ui file into python". Then you can use that feature with right-click on .ui files.
I could solve this issue to add this Path to my %PATH% Variable on windows.
C:\Users\<YOUR_USER_PATH_NAME>\AppData\Roaming\Python\Python311\Scripts
The pyside6-uic tool is supposed to be installed automatically when installing the Python package.
Check if uic is in PATH
When using loadUiType, the Qt documentation (here) states that :
The internal process relies on uic being in the PATH. The pyside6-uic
wrapper uses a shipped uic that is located in the
site-packages/PySide6/uic, so PATH needs to be updated to use that if
there is no uic in the system.
But even then, I got the following error :
Cannot run 'pyside6-uic': "execvp: No such file or directory" -
Exit status QProcess::NormalExit ( 255 )
Check if 'pyside6-uic' is in PATH
For me, pyside6-uic was not located in site-packages/PySide6/uic. When reinstalling the module with pip, I noticed this message :
WARNING: The scripts pyside6-assistant, pyside6-designer, pyside6-genpyi,
pyside6-linguist, pyside6-lrelease, pyside6-lupdate, pyside6-rcc and pyside6-uic are
installed in '/Users/<user>/Library/Python/3.8/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning,
use --no-warn-script-location.
So make sure to add the right directory to your $PATH variable.
Once it's done, you will be able to use the pyside6-uic command to generate a Python class from a UI file :
pyside6-uic mainwindow.ui > ui_mainwindow.py
Loading a .ui from code
You can also load a .ui file from your code using either:
loadUiType (doc page) :
This function generates and loads a .ui file at runtime, and it
returns a tuple containing the reference to the Python class, and the
base class.
or QUiLoader (doc page):
enables standalone applications to dynamically create user interfaces
at run-time using the information stored in UI files or specified in
plugin paths
from PySide6.QtUiTools import QUiLoader
ui_file = QFile("mainwindow.ui")
ui_file.open(QFile.ReadOnly)
loader = QUiLoader()
window = loader.load(ui_file)
window.show()
Generally speaking, use absolute paths to access your UI files. Relative paths are susceptible to errors.
I've been trying to add additional functionality to the electron installer, where I copy some files that are packaged inside the installer, but I receive a non-descriptive error when I try to compile my electron project to create the installer i.e. I get:
* writing effective config
* packaging
* building
x [object Object]
Here is what my script looks like:
!macro customInstall
Rename "$APPDATA\myfolder\img" "$APPDATA\myfolder\img-old"
SetOutPath "$APPDATA\myfolder"
File /nonfatal /a /r "additional_files\*"
CreateShortcut "$SMSTARTUP\mylink.lnk" "$INSTDIR\mylink.exe"
!macroend
Basically everything works except the file copy part. When I remove that part the project builds and compiles into an installer with no problems.
I've also tried to use CopyFiles instead of SetOutPath and File and it works as expected when I place the additional_files folder into the same folder as the installation (dist folder), but I want the folder to be packaged inside the installer. However, I cannot get the additional_files to be packaged with the installation.
I believe it's a location issue, that is, that the NSIS script cannot locate the additional_files/ folder. I've tried modifying the package.json file by adding to the files section the additional_files/ folder and placing it in the root of the project.
I've even tried placing it in the build folder where my installer.nsh script resides, but with no luck.
File looks for files relative to the directory where the .nsi is by default. /NOCD can be used to prevent that but I'm not sure if electron uses that switch.
!cd can be used inside a script to change the directory but I'm not sure if that is going to help you much in this case unless you are willing to use a absolute path and in that case you could just use the absolute path with the File instruction instead.
If you only know where your .nsh file is I suppose you could try File /r "${__FILEDIR__}\additional_files\*"
if you are using electron-builder you have two options inside the settings
extraResources this will copy files into the $INST_DIR/resources folder in your app (this is where the app.asar file is too), and you can access via process.resourcesPath, ex:
extraResources: [
{ from: './dist/ThirdPartyNotices.txt', to: 'ThirdPartyNotices.txt' },
]
extraFiles this would do the same but place the files into the $INST_DIR root folder of your installation ex:
extraFiles: [
{ from: './distrib/mytool.exe', to: 'mytool.exe' },
],
to get the root folder you can use something like remote.app.getAppPath().replace('resources\\app.asar', '').replace('resources/app.asar', '');

I am having a issue creating a yeoman project. I cd in the directory type yo and it says:
Here is it suppose to asked me project name etc and it wants to throw everything on my desktop not the file I cd into. It defaults to mvn and I want gradle. I even npm uninstall -g generator-jhipster
and reinstalled it and got the same issue.
If you have a .yo-rc.json file in a parent directory, Yeoman will load that configuration and generate from that file instead of prompting. This allows developers to run a yo command from any folder in the project and have it apply to the correct files.
To solve this, remove the .yo-rc.json from the parent directory, in your case /Users/drew/Desktop.
For example, if you are in the directory /Users/drew/Desktop/new-project but /Users/drew/Desktop has a .yo-rc.json inside, Yeoman will change to the parent directory (Desktop), load the configuration, and generate the files from that folder instead of the child folder.
Based on your log it's looks like you are running yo in a folder where a .yo-rc.json is already existing. Careful under windows the .yo-rc.json can be that is of type hidden and you can't see it in explorer. Because of an existing .yo-rc.json you are not asked anymore for info e.g. project name, build tool etc. My recommendation will be to create a new folder run inside yo command
I'm struggling with pyinstaller. Whenever I build this specific script with a kivy GUI and a .kv file, and run the .exe after the build, I get a fatal error:
IOError: [Errno 2] No such file or directory: 'main.kv'
I've tried adding the .kv file, as well as a mdb and dsn file (for pypyodbc) using --add-data, but I get an error: unrecognized arguments: --add-data'main.kv'. (There were more --add-data arguments for the other files mentioned.)
Are there any solutions for this or maybe alternative methods?
As others (#Anson Chan, #schlimmchen) have said:
If you want to add some extra files, you should use Adding Data Files.
Two ways to implement
Command Line: add parameter to --add-data
Spec file: add parameter to datas=
Generated when running pyinstaller the first time.
Then later you can edit your *.spec file.
Then running pyinstaller will directly use your *.spec file.
Parameter Logic
Parameter in --add-data or datas=:
--add-data:
format: {source}{os_separator}{destination}
os_separator:
Windows: ;
Mac/Linux/Unix: :
source and destination
Logic:
source: path to single or multiple files, supporting glob syntax. Tells PyInstaller where to find the file(s).
destination
file or files: destination folder which will contain your source files at run time.
* NOTE: NOT the destination file name.
folder: destination folder path, which is RELATIVE to the destination root, NOT an absolute path.
Examples:
Single file: 'src/README.txt:.'
multiple files: '/mygame/sfx/*.mp3:sfx'
folder: '/mygame/data:data'
datas=
Format: list or tuple.
Examples: see the following.
added_files = [
( 'src/README.txt', '.' ),
( '/mygame/data', 'data' ),
( '/mygame/sfx/*.mp3', 'sfx' )
]
a = Analysis(...
datas = added_files,
...
)
Your case
For your (Windows OS) here is:
--add-data in command line
pyinstaller -F --add-data "main.kv;." yourtarget.py
OR:
datas= in yourtarget.spec file, see following:
a = Analysis(...
datas = ["main.kv", "."],
...
)
If you check pyinstaller -h for help, you can find --add-data option works like this [--add-data <SRC;DEST or SRC:DEST>]. So in your case try
pyinstaller -F --add-data "main.kv;main.kv" yourtarget.py
The solution is to run: pyi-makespec yourscript.py
Then edit the yourscript.spec script and add the files under datas in a= Analysis.
datas=[ ( '/pathToYourFile/main.kv', '.' )]
then run pyinstaller yourscript.spec
should be good after that.
Next -F or --onefile option is assumed when running pyinstaller.
Note that (MacOS Monterey, 12.2 here) the expected folder hierarchy w/in you .app file will be similar to this,
pyinstaller does not add files nor create necessary folders into any of the folders of this folder structure; at least not in any apparent way. You won't find them.
However, when the application runs, a temporary folder is used under /var/folders which is very different from the folder structure in point 1. above. print(os.path.dirname(__file__)) while running the application will reveal which exact temporary folder is used each time it runs. For convenience, let's call it my_app_tmp_folder i.e. your app runs under the folder /var/folder/my_app_tmp_folder
Then, pyinstaller adds data files or creates necessary directories w/in this temporary folder. In other words, when the application runs, all added files will be there and according to the specified folder structure (through --add-data option). print(os.listdir(os.path.dirname(__file__))) will show system and application needed files and folders.
Bottom line: Files specified w/ --add-data option will be visible w/in /var/folder/my_app_tmp_folder when running and not w/in the *.app folder.
Some useful links from documentation:
https://pyinstaller.readthedocs.io/en/stable/runtime-information.html#using-file

https://pyinstaller.readthedocs.io/en/stable/operating-mode.html#bundling-to-one-file
My application had this issue and a subsequent issue that is likely, if not inevitable.
1. --add-data for a kv file
Use --add-data as in the answer by crifan.
2. Kivy still can't find the file
Once PyInstaller has the kv file in the correct directory, Kivy still can't find the file.
Possible Symptoms:
GUI launches, but screen is black and empty.
An AttributeError error that depends on the application code.
AttributeError Examples:
This question
My own case:
AttributeError: 'NoneType' object has no attribute 'ids'
Fortunately, this answer solves the problem.
During the reproduction of this example, something strange happend: https://github.com/dart-lang/dart_by_example/tree/master/example/angular/basics/conditionally_switch_between_dom_elements
So created a plain Dart project in WebStorm, added angular.dart, copied the example. Everything works well, if the files are "web" directory.
BUT, after I moved the three files into a switch subdirectory, I have the following problem:
An error occurred loading file: package:angular/angular.dart
Do you have any idea? What did I missed.
If you added the subdirectory after you ran pub get then it may not have the packages symlink folder. Try running pub get (from your apps root directory) again which should generate any missing packages in subdirectories that may have been added, without re-downloading any dependencies.
