curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

curl: (7) Failed to connect to raw.githubusercontent.com Port 443: several solutions to connection reused?

Preface:
recently, with the release of flutter, most companies begin to use it. But if you want to develop, you need to build a flutter development environment first. You can follow the official website for the installation of flutter. Here we are going to talk about homebrew

curl: (7) Failed to connect to raw.githubusercontent.com Port 443: connection reused note that the suffix is connection reused

My guess: the possible reason for the failure of the installation is that the Xcode environment was not initialized. This is for MAC computers. I found a lot of information on the Internet, and it was said that I could open this website https://raw.githubusercontent.com/Homebrew/install/master/install , I can’t open it
so here’s my solution:

    1. solution 1
    1. (1) open the website:

https://www.ipaddress.com/
check out raw.githubusercontent.com corresponding IP address

(2) replace the host file of the system
note: it's better to copy it before changing


this is actually equivalent to the solution to the problem of network failure. If a web address can be opened on your computer, we will ping it at the terminal (DOS system).
for example:

this is the status of connection. Generally, timeout will be displayed if it is not available. You can try to see if your GitHub is connected（ The same is true for general telecom companies to check network problems, to see if there is packet loss.)

(3) Then install
/bin/bash - C "$(curl - fssl) https://raw.githubusercontent.com/Homebrew/install/master/install.sh ）"
explain: this line/bin/bash – C” $(curl – fssl) https://raw.githubusercontent.com/Homebrew/install/master/install.sh ）”The command is actually the command to install homebrew, You can check the official website address by yourself.

2. Solution 2
execute the following command sudo gem install redis
and then execute /usr/bin/Ruby - e "$(curl - fssl) https://raw.githubusercontent.com/Homebrew/install/master/install )

3. Solution 3
I read other people’s brew_ install.rb The document, which is the website that can’t be opened, is the website https://raw.githubusercontent.com/Homebrew/install/master/install , the corresponding content is brew_ install.rb In fact, many people on the Internet have posted this file, and I have also posted one:
link: Baidu cloud download
password: 1ogr

Enter store brew_ install.rb Execute Ruby brew_ install.rb just follow the prompts to install

4. Solution 4
if the above three methods still have some problems in the installation process, you can try this method.

Step 1: go directly to the GitHub address of homebrew [portal], and pay attention to select the version when downloading. Click branch to switch to tags. Generally, this is the release version
Step 2: after downloading and decompressing, right-click visit, select go to folder…, and enter /usr/local Enter. Just find the homebrew folder in it and replace it with the content you downloaded from GitHub

After that, check whether brew is installed on your Mac, and enter brew

on the terminal to indicate that the installation is completed.

MAC Wireshark Permission issues (you don’t have permission to capture on that device Mac)

The solution is as follows:

1 – open terminal

Look at the name of your actual user

2 – enter the command ‘whoamI’

3 – enter/dev directory CD/dev

4 – enter the command ‘LS – La | grep BP’

5 – enter the result of the command ‘sudo chown whoamI: admin BP *’

6 – turn on Wireshark again and it’s OK

Solve the problem of [newnullresponse] when updating MAC app store

This problem mostly occurs after you reload the system, because of the problems in the store area. The solution here is to clear the data and get it again.

Thank you to Josh from wings mills, because this method is provided by him. The original address is here: https://discussions.apple.com/message/23544639#23544639

No nonsense, just look at the steps

1) Exit app store

2) Open the activity monitor and search for “store”. Then force the following two processes to terminate:

A) com.apple.appstore .Plugin…；
B) storeagent,

3) Open the terminal, input the following command and execute it:

rm ~/Library/Preferences/ com.apple.appstore .plist

rm ~/Library/Preferences/ com.apple.storeagent .plist

rm -rf ~/Library/Preferences/ByHost/*

Note that the above three commands are executed one by one.

4) Open the app store again and everything is OK.

What if it’s not normal?Hammer it, of course, I will not be responsible for smashing, you have to buy again.
