Solution
I’ve tried all the solutions to this problem on the Internet. I’ve also tried to change the source, uninstall and reload CONDA, but it’s not easy to use
finally! I found my network agent on!!! Just turn it off
you can check whether your network agent is on or off. Or refer to the great gods blog to set up a proxy, but I won’t, I just simply and rudely turn it off.

Solve the problem that M1 Mac can’t debug when using GoLand
The general error information is as follows:
API server listening at: [::]:57824
debugserver-@(#)PROGRAM:LLDB PROJECT:lldb-1200.0.44
for x86_64.
error: failed to launch process /Library/Developer/CommandLineTools/Library/PrivateFrameworks/LLDB.framework/Versions/A/Resources/debugserver: (os/kern) invalid argument
Exiting.I use go 1.16, which supports arm architecture. The reason for this problem is that go debug needs DLV tool, which also needs arm architecture.
The easiest way to solve this problem is to go to the official website to update GoLand. Pay attention to go to the official website to download the latest arm version again. Usually, the update prompted in the IDE can only be regarded as a patch, not a big version update. In this way, the debugging tools of IDE are adapted to arm architecture.
Of course, due to various reasons that cannot be described, some users may not be suitable to go to the official website to update, so you can refer to this link https://youtrack.jetbrains.com/issue/GO-10235#focus =Comments-27-4632451.0-0
Download the DLV debugging tool of arm architecture, and then configure it in IDE.

Cause of the problem
After inheriting the parent class, the constructor of the parent class is not called.
resolvent
There are two solutions: 1) call the same constructor as the parent class; 2) Use inheritconstructors annotation;
Call the same constructor as the parent class
class Creature {
Creature (String feature) {}
}
class Humman extends Creature{
Humman (String feature) {
super(feature)
}
}
new Humman("legs")
Using inheritconstructors annotation
class Creature {
Creature (String feature) {}

Error analysis:
Starting from 9.0 (API level 28) on Android, plaintext communication support is disabled by default, which is officially said to be unsafe. Because the video source we play is HTTP protocol, we can’t play it.
Idea 1: add uses cleartext traffic
Indicates whether the application intends to use plaintext network traffic, such as plaintext http. The default value for applications with a target API level of 27 or lower is “true.”. For applications with API level 28 or higher, the default value is “false”.
<!--Android 9.0 video playback function-->>
<application
android:usesCleartextTraffic="true"
>
</application>
After modification, some models are still not feasible.
Idea 2: Android access to x5webview
Better article links: https://www.cnblogs.com/cuichen16/p/10785945.htm
After adding, Android 10.0 or above is not feasible for higher version mobile phones
Idea 3: setmixedcontentmode
//Allow cross-domain
webSetting.setAllowFileAccessFromFileURLs(true);
webSetting.setAllowUniversalAccessFromFileURLs(true);
webSetting.setSupportMultipleWindows(true);
if (Build.VERSION.SDK_INT >= 21) {
webSetting.setMixedContentMode(android.webkit.WebSettings.MIXED_CONTENT_ALWAYS_ALLOW); // This sentence is crucial and can be added after
}
Finally, after adding the above three contents, the last step can be finished. If not, please continue to Baidu and keep looking for the key code.
Elememt UI introduces components on demand to report errors
Background: the project based on vue-cli3 introduces error reporting on demand
According to the official documents, introduce components as required, as follows:
1. Install: NPM install Babel plugin component – d
2 babel.config.js Modify configuration in
module.exports = {
presets: [["es2015", { modules: false }]],
plugins: [
[
"component",
{
libraryName: "element-ui",
styleLibraryName: "theme-chalk",
},
],
],
};
3. After running, Babel compiles and reports an error:
cannot find module ‘babel-preset-es2015’
4. Query the document and find the following sentence:
this preset is not recommended. If you want to keep it up to date, please use env preset
5. Solution:
1) install NPM install — save dev @ Babel/preset env
2) modify babel.config.js “Es2015” is “@ Babel/preset env”
3)
Official website link reference: https://babel.docschina.org/docs/en/6.26.3/babel-preset-es2015/

this is because I need to configure appkey

Nginx Error: [emerg] bind() to [::]:80 failed (98: Address already in use)
Problem description
When starting the nginx service, the following error occurred:
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to [::]:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to [::]:80 failed (98: Address already in use) ...
Cause of the problem
There are many reasons for this problem. We will list our scenarios and solutions here.
First, the port is occupied
This is the most common reason. Port 80 is occupied, which leads to binding of nginx service.
Solution 1
Find the process occupying port 80 and end it.
Second, dual stack sockets for IPv6
This is a common problem in the transition period from IPv4 to IPv6. The following configuration will also cause the above error:
server {
listen [::]:80 ipv6only=off;
server_name dual-stack.example.com;
}
server {
listen 0.0.0.0:80;
server_name ipv4.example.com;
}
With the IPv6 only = off option, the currently created socket is dual stack, and IPv4 will be mapped to IPv6. At this time, only one monitor can be created, and IPv4 can no longer be monitored.
Solution 2
Since we can’t monitor IPv4, and now it’s a dual stack, we can monitor IPv6 address safely (and ensure IPv4 access at the same time)
server {
listen [::]:80 ipv6only=off;
server_name dual-stack.example.com;
}
server {
listen [::]:80;
server_name ipv4.example.com;
}
# Because of the specific scenario, we cannot modify the configuration of the first Server
# Of course, it is also possible to turn off the double stack.
