The fastest way to solve the problem of error reporting from crypto.cipher import AES

In my personal development process, I need to use the encryption method, but in the process of quoting from crypto.cipher import AES, it has been reported that the crypto module does not exist. Baidu finally found a solution after a few days

 

I use Python 3.9

1、 First perform the following 2 steps

1.pip   install crypto

2.pip   install pycryptohome

2、 After the installation is completed, you can use it directly or prompt that it cannot be found:

1. Change crypto to uppercase

 

So far, the problem has been solved

GPY installation error: ERROR: Could not find a version that satisfies the requirement scipy…

The following error occurs when installing GPY with PIP

Solution: use PIP3

pip3 install GPy

[Solved] Error Mixed spaces and tabs no-mixed-spaces-and-tabs

"extensions": "eslint: Recommended" the attribute in the configuration file enables this rule.

Most code conventions require tabs or spaces for indentation. Therefore, if a single line code is indented with tabs and spaces, an error usually occurs.

This rule does not allow indenting with mixed spaces and tabs.

Example of error code for this rule:

/*eslint no-mixed-spaces-and-tabs: "error"*/

function add(x, y) {
// --->..return x + y;

      return x + y;
}

function main() {
// --->var x = 5,
// --->....y = 7;

    var x = 5,
        y = 7;
}

Example of the correct code for this rule:

/*eslint no-mixed-spaces-and-tabs: "error"*/

function add(x, y) {
// --->return x + y;
    return x + y;
}

This rule has a string option.

"smart tabs" when the latter is used for alignment, it is allowed to mix space and labels.

Smart tag

The correct code example for this rule includes the following "smart tabs" Options:

/*eslint no-mixed-spaces-and-tabs: ["error", "smart-tabs"]*/

function main() {
// --->var x = 5,
// --->....y = 7;

    var x = 5,
        y = 7;
}

Add this line:

/*eslint no-mixed-spaces-and-tabs: [“error”, “smart-tabs”]*/


<template>
	<comp-setup>
		
	</comp-setup>
</template>

<script>
/*eslint no-mixed-spaces-and-tabs: ["error", "smart-tabs"]*/
import CompSetup from './components/setupview'
export default {
  name: 'App',
  components: {
	  CompSetup,
  }
}
</script>

Robotframework post error“:“Internal Server Error“,“message“:“syntax error, expect

In the post request,
‘content type’: ‘application/JSON; Charset = UTF-8 ‘
data = ${data} is used to transfer parameters, resulting in an error

Error “:” internal server error “,” message “:” syntax error, expect

Solution:
After changing data=data to json{data}, the execution succeeds
PS: in the post request, data parameters need to be transferred according to the content type

When using python3 to do text-to-speech, I installed pyttsx3 and ran the program with the above error
The reason is that before installing pyttsx3, I need to install a speech environment: “espeak”
Installation command:

sudo apt-get update && sudo apt-get install espeak

Python Error: SyntaxError: ‘break‘ outside loop

report errors:

SyntaxError: 'break' outside loop

Break can only be used in a while loop or a for loop. If it is used in an if conditional statement, an error will be reported: syntax error: ‘break’ outside loop. However, if the if conditional statement is nested inside a while loop or a for loop,
if you do not pay attention to the format when corresponding to while, an error will also be reported
