i changed folder name to mian_screen and then when i run it gives error and cant find the path any more as you see in image.image of error
You can change the way you are importing things.
Instead of doing import '../models/orders.dart
Try import 'package:firstproject/models/orders.dart

Can anyhelp help what I can do to make my test module import , It seems right now its not able to find the test folder itself .
In my last flutter project, I included files placed in my lib/ directory by using import 'package:app/file_name.dart'.
For example, my file located at lib/app_controller.dart was imported via:
import 'package:app/app_controller.dart'
I just started a new flutter project, and it is giving me the error:
Error: Could not resolve the package 'app' in 'package:app/app_controller.dart'
When I remove the portion package:app/, it builds fine. I find this very strange because my previous project is still building just fine without any changes. Does anyone know what's happening here?
What is allowing my old project to respect package:app/..., but not my new project?
package:app/ would work only for an application that is called app. What is the name of your new application? When you import items from your own project, it goes like this:
package:{{YOUR APPLICATION NAME}}/{{DIRECTORIES}}
What is the name in your pubspec.yaml file? It's usually on the very first line.
it is because a dart class can be imported in two ways(AFAIK),
local import from the root of current file where import is being used for example import '../folder/file.dart
with a package name which should begin from package for example import package:packagename/any_file_in_the_lib_folder.dart, a package will have a pubspec.yml which defines a package name which will be used to import the content of the lib folder of that package, in your case your first project is named app so it respected this import style but your second project isn't respecting it because its not named app but something else.
I use PyCharm and Eclipse with PyDev.
To be specific, I am using Odoo and setting up project.
https://github.com/odoo/odoo
Here is the folder structure.
odoo-12
|-addons
| '-web
| '-...
|-odoo
'-addons
'-...
In source code for example:
addons/purchase/controllers/portal.py
# Unresolved yet this is the official source code
from odoo.addons.web.controllers.main import Binary
# Resolved perfectly
from addons.web.controllers.main import Binary
I understand the reason why this one works
from addons.web.controllers.main import Binary
but how can I make this works instead?
from odoo.addons.web.controllers.main import Binary
I cannot and should not modify any Odoo source code to make IDE resolving path correctly
In Eclipse/PyDev you should be able to set your source folder to the folder containing odoo and it should work...
I'm having trouble importing magellan-1.0.4-s_2.11 in spark notebook. I've downloaded the jar from https://spark-packages.org/package/harsha2010/magellan and have tried placing SPARK_HOME/bin/spark-shell --packages harsha2010:magellan:1.0.4-s_2.11 in the Start of Customized Settings section of the spark-notebook file of the bin folder.
Here are my imports
import magellan.{Point, Polygon, PolyLine}
import magellan.coord.NAD83
import org.apache.spark.sql.magellan.MagellanContext
import org.apache.spark.sql.magellan.dsl.expressions._
import org.apache.spark.sql.Row
import org.apache.spark.sql.types._
And my errors...
<console>:71: error: object Point is not a member of package org.apache.spark.sql.magellan
import magellan.{Point, Polygon, PolyLine}
^
<console>:72: error: object coord is not a member of package org.apache.spark.sql.magellan
import magellan.coord.NAD83
^
<console>:73: error: object MagellanContext is not a member of package org.apache.spark.sql.magellan
import org.apache.spark.sql.magellan.MagellanContext
I then tried to import the new library like any other library by placing it into the main script like so:
$lib_dir/magellan-1.0.4-s_2.11.jar"
This didn't work and I'm left scratching my head wondering what I've done wrong. How do I import libraries such as magellan into spark notebook?
Try evaluating something like
:dp "harsha2010" % "magellan" % "1.0.4-s_2.11"
It will load the library into Spark, allowing it to be imported - assuming it can be obtained though the Maven repo. In my case it failed with a message:
failed to load 'harsha2010:magellan:jar:1.0.4-s_2.11 (runtime)' from ["Maven2 local (file:/home/dev/.m2/repository/, releases+snapshots) without authentication", "maven-central (http://repo1.maven.org/maven2/, releases+snapshots) without authentication", "spark-packages (http://dl.bintray.com/spark-packages/maven/, releases+snapshots) without authentication", "oss-sonatype (https://oss.sonatype.org/content/repositories/releases/, releases+snapshots) without authentication"] into /tmp/spark-notebook/aether/b2c7d8c5-1f56-4460-ad39-24c4e93a9786
I think file was to big and connection was interrupted before whole file could be downloaded.
Workaround
So I downloaded the JAR manually from:
http://dl.bintray.com/spark-packages/maven/harsha2010/magellan/1.0.4-s_2.11/
and copied it into the:
/tmp/spark-notebook/aether/b2c7d8c5-1f56-4460-ad39-24c4e93a9786/harsha2010/magellan/1.0.4-s_2.11
And then :dp command worked. Try Calling it first, and if it will fail copy JAR into the right path to make things work.
Better solution
I should investigate why download failed to fix it in the first place... or put that library in my local M2 repo. But that should get you going.
I would suggest to check this:
https://github.com/spark-notebook/spark-notebook/blob/master/docs/metadata.md#import-download-dependencies
and
https://github.com/spark-notebook/spark-notebook/blob/master/docs/metadata.md#add-spark-packages
I think the :dp magic command is depreciated, instead you should add your custom dependencies in the notebook metadata. You can go in the menu Edit > Edit notebook metadata, there add something like:
"customDeps": [
"harsha2010 % magellan % 1.0.4-s_2.11"
]
Once done, you will need to restart the kernel, you can check in the browser console if the package is being downloaded properly.
The easy way, you should set or add the EXTRA_CLASSPATH environnent variable to point to your .jar file downloaded :
export EXTRA_CLASSPATH = </link/to/your.jar> or set EXTRA_CLASSPATH= </link/to/your.jar> in wondows OS. Here find the detailed solution.
Noob alert!
I'm wondering how you go about importing a module(one made in qpython)?
I've tried making a new folder and adding a setup.py then trying to import but just get error about module not found(or something)..
Thanks in advance
Your folder must to consist in Path variable.
You must append path to your folder in this variable.
Add the following lines to the top of your project main file:
import sys
sys.path.append(yourPath)
yourPath must be a string type. For example:
'/storage/sdcard0/myfolder'
