I have a truffle project with the following contract (elided) that I'm running with truffle migrate:
1 pragma solidity >=0.6.0;
2
3 // implements the ERC721 standard
4 import "#openzeppelin/contracts/token/ERC721/ERC721.sol";
5 // keeps track of the number of tokens issued
6 import "#openzeppelin/contracts/utils/Counters.sol";
7 import "#openzeppelin/contracts/access/Ownable.sol";
But I'm getting the following error:
> Compiling ./contracts/NFT.sol
> Compilation warnings encountered:

Compilation failed. See above.
Truffle v5.4.0 (core: 5.4.0)
Node v14.15.5
How to fix this error?
Even though my contract works I had the same error... I just changed:
import "#openzeppelin/contracts/utils/Counters.sol";
To a more explicit form:
import "../node_modules/#openzeppelin/contracts/utils/Counters.sol";
and bypass those red squiggles.
Have you run the following commands
$ npm init
$ npm i -s #openzeppelin/contracts

And here: https://github.com/snowflakedb/snowflake-sqlalchemy/issues/350 it was supposed to upgrade to v1.4.3 version but getting the below error when trying to upgrade.
Used command: pip install snowflake-sqlalchemy==1.4.3
Error
`

Can someone please help with the issue?
Tried to upgrade to the latest version which is not the latest.
The issue was resolved by upgrading python to 3.9 and then upgrading sqlalchemy to 1.4.3
I have a selenium python automation test, it works fine, now I want to generate Html and JSON reports and have screenshots in the report using pytest. I am new to automation and python so I am not much aware of how its done.
following is my code
test_screenshot.py
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import pytest_html
from selenium.common.exceptions import InvalidSessionIdException
def test_Openurl(setup):
driver = setup["driver"]
url = setup["url"]
try:
driver.get(url)
except Exception as e:
print(e.message)
assert driver.current_url == URL
driver.save_screenshot("ss.png")
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
driver.save_screenshot("ss1.png")
driver.close()
conftest.py
import pytest
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service
def pytest_addoption(parser):
parser.addoption("--url", action="store", default="https://google.com/")
#pytest.fixture()
def setup(pytestconfig):
s = Service("C:/Users/Yash/Downloads/chromedriver_win32/chromedriver.exe")
driver = webdriver.Chrome(service=s)
driver.maximize_window()
yield {"driver":driver, "url": pytestconfig.getoption("url")}
I ran this using
pytest test_screenshot.py --url "https://www.netflix.com/in/"
Test case is passed. How do I generate HTML and JSON report?
I tried this
pytest -v -s --json-report --json-report-indent=4 --json-report-file=report/report.json --html=report/report.html test_screenshot.py
but got this error
ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: unrecognized arguments: --json-report --json-report-indent=4 --json-report-file=report/report.json

You need to install these two libraries : https://pypi.org/project/pytest-json-report/ & https://pypi.org/project/pytest-html/
I got below error, try adding signature to my angular 6 project
node module : - angular-signature-pad
error: - ERROR in src/app/app.module.ts(5,41): error TS2307: Cannot find module 'angular-signature-pad'.
Things to check?
1) Did you install the package ?
npm install angular-signature-pad --save
2) Import the package in app module.
import { AngularSignaturePadModule } from 'angular-signature-pad';
#NgModule({
imports: [
...
AngularSignaturePadModule.forRoot()
]
...
})
export class AppModule { }
Maybe possibility, It may not be working in angular 4 plus.

try updating node.js to version 16+
or
update angular cli
ng update #angular/cli #angular/core
I am trying to execute my python script which imports globally installed modules through pip. (Module like nltk)
Below is my code.
interpreter.execfile("/home/roy/eclipse-workspace/geospatial-analysis/src/main/resources/wordnet_util.py");
PyObject someFunc = interpreter.get("get_similarity");
PyObject result = someFunc.__call__(new PyString("Apple pie."), new PyString("Banana pie."));
Double realResult = (Double) result.__tojava__(Double.class);
I have added the path for python modules like,
import sys
sys.path.append("/usr/local/lib/python2.7/dist-packages")
But I get the following error,
*sys-package-mgr*: can't create package cache dir, '/usr/local/lib/python2.7/dist-packages/cachedir/packages'
Exception in thread "main" Traceback (most recent call last):
File "/home/roy/eclipse-workspace/geospatial-analysis/src/main/resources/wordnet_util.py", line 6, in <module>

File "/usr/local/lib/python2.7/dist-packages/nltk/__init__.py", line 18, in <module>
from __future__ import print_function, absolute_import
ImportError: No module named __future__
Update:
I added sys.path.append("/usr/lib/python2.7") to the python file. It solved the above error. Now it can't find select module.
ImportError: No module named signal

So what's wrong?
Thanks!
The error message is exactly what it says. You cannot use ES6 module syntax in the REPL, it is unsupported. You can create a small adapter that imports as ES6 and exports as CommonJS:
# es6-to-common.js
import MyThing from './somewhere';
module.exports = MyThing;
Now inside your usual babel-node prompt:
> MyThing = require('./es6-to-common')
Got it from the official doc：http://babeljs.io/docs/usage/cli/
ES6-style module-loading may not function as expected
Due to technical limitations ES6-style module-loading is not fully supported in a babel-node REPL.
