The meta-buy of pdf.js has been annotated with the following code:
// if (origin !== viewerOrigin && protocol !== 'blob:') {
// throw new Error('file origin does not match viewer\'s');
// }
The main reason is: the HTTPS website loads the PDF resource file address of HTTP, and the PDF resource file address of HTTPS needs to be provided.
Generally, it is a version problem. When installing the webpack module with NPM install, specify the version, for example:
npm install [email protected] --save-dev
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) })
}
})

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:

First, Ping github.com to test whether it can connect. Then modify the host.
Step 1: open ipaddress.com, query the following two domain names and record their corresponding IP addresses:
1.github.com
2.github.global.ssl.fastly.netStep 2: update the host file
140.82.114.3 github.com
199.232.69.194 github.global.ssl.fastly.netStep 3: clean up DNS and try again.
