[Solved] NPM Error: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed

This error is reported when NPM run build is executed to package Vue project, because the maximum value of node file set is not enough and the file after project packaging is too large.

Solution: install increase memory limit globally

Command line CMD, DOS window running: cnpm install – G increase memory limit,

Enter the project folder and run: increase memory limit

If NPM run build reports an error ‘node — Max old space size = 10240’ after executing increase memory limit after entering the project file, it is neither an internal or external command nor a runnable program ‘

You can create the following JS file contents in the project root directory, execute the file with node, and then run NPM run build to package successfully. This is to replace the public function of the string in the file corresponding to the. Bin file under the node_mosules file.

// Execute this script via node the first time you run the project
const fs = require('fs')
const path = require('path')
const wfPath =  path.resolve(__dirname, './node_modules/.bin')

fs.readdir(wfPath, (err, files)=>{
   if (err) {
    console.log(err);
   } else {
      if(files.length != 0 ) {
        files.forEach((item)=>{
           if(item.split('.')[1] === 'cmd') {
              replaceStr(`${wfPath}/${item}`, /"%_prog%"/, '%_prog%')
           }
        })
     }
   }
 })

// Parameters: [file path, string to be modified, modified string] (public function to replace the string in the corresponding file)
function replaceStr(filePath, sourceRegx, targetSrt) {
  fs.readFile(filePath, (err, data)=>{
     if(err) {
     console.log(err)
     } else {
       let str = data.toString();
     　str= str.replace(sourceRegx, targetSrt);
       fs.writeFile(filePath, str, (err)=> { console.log(err) })
     }
  })
}

Git Push Error: error: failed to push some refs… hint: Updates were rejected because the remote…

1. The questions are as follows:

echigh@huangchenggong:/mnt/e/work/workspace/withdraw_validdata_from_file/withdraw$ git push -u origin main
Username for 'https://github.com': echigh
Password for 'https://[email protected]':
To https://github.com/echigh/withdraw_frontbytes_of_file.git
 ! [rejected]        main -> main (fetch first)
error: failed to push some refs to 'https://github.com/echigh/withdraw_frontbytes_of_file.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

2. The reason is that the remote warehouse has been changed and does not match any local commit version

Reference: [status question] why can’t you push it up sometimes… – learn git for yourself

3. Solution:

1) Merge remote changes with git pull before git push

2) Directly use git push – F to forcibly overwrite the remote warehouse. Anyway, I dare not

4. So I did this:

echigh@huangchenggong:/mnt/e/work/workspace/withdraw_validdata_from_file/withdraw$ git pull

Solution to [SSL: certificate_verify_failed] when you get downloads video

[SSL: certificate_verify_failed] problem when downloading video using you get and ffmpeg

Since the you get -- debug debugging shows that it is a certificate verification problem, the part ignoring SSL certificate verification is added to the code and implemented in pycharm (non command line)
Modify url = 'website', output_Dir = R 'save path' 

import ssl
from you_get import common

# Ignore certificate validation issues
ssl._create_default_https_context = ssl._create_unverified_context

# Call any_download_playlist in you_get.common to download a collection
common.any_download_playlist(url='https://www.bilibili.com/video/BVXXX',stream_id='',info_only=False,
                             output_dir=r'F:\StudyLesson\YouGet',merge=True)

# Call any_download in you_get.common for single set download
common.any_download(url='https://www.bilibili.com/video/BVXXX?p=8',stream_id='',
                    info_only=False,output_dir=r'F:\StudyLesson\YouGet',merge=True)

So far, the video has been downloaded successfully

IntelliJ idea error: Java: compilation failed: solution to internal java compiler error

Method 1: it may be due to heap memory problems

In setting — & gt; Build,Execution,Deployment–> Build process heap size (Mbytes) found in compiler: 700 changed to 1024 (as appropriate)

Method 2: it may be due to project coding

PS: I can compile it by changing it to GBK. The system default GBK format is invalid and needs to be manually changed to GBK
