Processing method of eslint verification error

Processing method of eslint verification error

When encountering the eslint verification rule, the following errors or warnings are reported:

1. When encountering no unused vars, no unused expressions, no undef, no restricted globals and other errors, you can verify that the function is turned off by configuring the rules in eslint
2. If there are too many errors and warnings when encountering a file (such as the imported plug-in min.js), you can create it in the root file = & gt Eslintcore (don’t forget the previous point) and configure it, as shown in the following figure:
/SRC/view = & gt; The view file under SRC file ignores the verification

1. If eslint is configured in a separate file

Configure the required verification rules in the created. Eslintrc.js, as shown in the following figure:

2. Referenced scaffolds, such as create react app

Configure verification rules in package.json:

Vue console reports an error duplicate keys detected: ‘XXXX’. This may cause an update error. Solution

Q: the Vue console reports an error duplicate keys detected: ‘XXXX’. This may cause an update error. Solution

Analysis: duplicate key: ‘0’. 0 ‘may cause an update error; This problem usually occurs because there are multiple V-for loops on the same page, and the key of the loop is index. You can define the key as a unique value, such as code or ID. this can be solved
A: the value of the drop-down box must be unique. Check the value of the drop-down box

click the picture to see that it is actually an error message from javamailsender. First, check whether the configuration file is configured to send mail

If the project is used with Nacos, check the local configuration file xxx.yml to see if the Nacos configuration is annotated. As shown in the following figure, if the annotation is, you can uncomment it.

Ts-node Error: return new TSError(diagnosticText, diagnosticCodes);

TS node can help us run the TS code without manually converting it into a JS file

But we passed

npm install -g typescript
npm install -g ts-node

After installing the two packages, running the file with the TS node command may report an error and cannot be executed

At this time, we need to install one more dependency package

npm install -D tslib @types/node

Just run it with TS node

Solve the problem of error reporting from scipy.misc import imread & imresize in Python

from scipy.misc import imread& imresize

Problem description solution 1 solution 2

Problem description

from scipy.misc import imread # error

After query, the reason is that the from scipy.misc import imread, imwrite and other methods have been abandoned, and python has encapsulated the imread method in the imageio module

Solution 1

To install the imageio Library:

pip install imageio

Normal use!

import imageio
imageio.imread("xxxx.png")

Solution 2

If the higher version is discarded, we can reduce the SciPy version!

Reduce the SciPy version to 1.2.1 

pip install scipy==1.2.1

[Solved] Github Push Codes Error: “error:RPC failed;curl 56 OpenSSL SSL_read:SSL_ERROR_SYSCALL,errno 10054”

Error description

At the weekend, I did something with my computer, installed GitHub again, and reported an error “error: RPC failed” when I made some changes to the cloning project and prepared to push it; curl 56 OpenSSL SSL_ read： SSL_ ERROR_ Syscall, errno 10054 “, searched various solutions on the Internet. It is found that the GIT upload file has a limited file size. Just set the cache size.

Solution

Use Git   Bash enter the code under the current project:

git config --global http.postBuffer 1048576000

Globally set the cache size to 1g, and the problem is solved. I guess this may be because I use HTTPS. I don’t encounter this problem with SSH transmission and pull code in my office.

[Solved] VMware error: The module “PhysMem” failed to start.

How to re-install VMware and import the previously installed virtual machine with an error

The set physical address width exceeds the maximum value of 43 bits.

The module "PhysMem" failed to start.

Let me talk about the status of my virtual machine first. The virtual machines I installed before are not shut down directly and are in a suspended state.

After searching the Internet for many results, I chose to turn off the virtual power supply (power – & gt; Shutdown). After shutdown, restart the virtual machine to run normally

[Solved] UMI Project Error: uncaught at _callee3 at _calle3

1. If it is just a react project and the DVA framework is introduced, an onerror attribute will be passed in when calling the DVA method

const app = dva({
	onError(err) {
		// error
		console.log(err);
	},
});

2. If you are using the UMI framework, you cannot find the place where the DVA is called. Create a new app.js file in the SRC directory and write the following contents

export const dva = {
  config: {
    onError(e) {
      e.preventDefault();
      console.error(e.message);
    },
  },
};
