error:0308010C:digital envelope routines::unsupported
This error occurs because of the recent release of OpenSSL3.0 in node.js V17 version, and OpenSSL3.0 adds strict limits on allowed algorithms and key sizes, which may affect the ecosystem cause some impact.
Some applications that can run normally before node.js V17, but in V17 and above versions may throw the following exceptions:
node:internal/crypto/hash:67
this[kHandle] = new _Hash(algorithm, xofLen);

Node.js v18.7.0
✨ Done in 1.92s.
It is said that this can be temporarily fixed by running the following command line
export NODE_OPTIONS=--openssl-legacy-provider
But the current test does not work, so I reinstalled node-v16.12.0, and npm also installed the corresponding version
Refer to https://nodejs.org/en/download/releases/ for the correspondence between node and npm versions
After android9.0, WebView can’t load the link starting with HTTP, or an error is reported.
Solution:
1. Add android:usesCleartextTraffic = true in the Application tag of AndroidManifest;
2. Set in webclient
webView.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
if (url.startsWith("http://") || url.startsWith("https://")) {
webView.loadUrl(url)
return true
}
return true
}
}1. Background
Unity project has the following capabilities
1. It can run directly on Android phones
2. You can build an APK file and then install it on the mobile phone to run
3. It can be packaged into an Android project and run the project using Android studio
There may be no problem that 1 and 2 can be implemented normally, but an error will be reported when implementing the third method
the first error:
unity UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&) (at /Users/bokken/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:189)
the second error:
UnityEditor.BuildPlayerWindow Error
2. Precautions
1. There is no problem with the configuration of gradle environment, because it can be compiled normally
2. The package directory also has no Chinese name
3. There is no problem with the packaging configuration
3. Solutions
Exporting Android Studio project needs to be consistent with our project name of unity
For example: File-BuildSettins-PlayerSetting-Player-ProductName name and File-BuildSettins-Build file directory name consistent can be solved
Failed to find data source: kafka. Please deploy the application as per the deployment section of "Structured Streaming + Kafka Integration Guide"The reason for this error is the lack of spark-sql-kafka-0-10_2.11-2.4.5.jar dependency
Download the jar package, put it on the server, and add it to the submission command
–jars spark-sql-kafka-0-10_2.11-2.4.5.jar
Error is still reported, and error is reported at this time

I. Problems
Due to the project requirements: you need to build an FTP. After setting up the folder, create a new user and grant corresponding permissions. The following error message appears when I log in to the FTP site.
My running environment: centos8.2 64bit
II. Solutions (Four Methods)
There are four ways to collect online information. Please choose different solutions according to your own problems
(1) the host to log in does not create an account and its corresponding permissions.
cat /etc/passwdIf you find that you don’t have the account you created, create another one.
(2) after entering the correct password, it still reports an error. Users’ passwords can be modified;
Command: passwd username
Try signing in again. If you still report an error, look again (3)
(3) comment out pam_shells.so
FTP allows local users to log in. As a result, this error is always reported when logging in. I found a lot of information on the Internet, and finally solved it:
backup:
cp /etc/pam.d/vsftpd /etc/pam.d/vsftpd.bakModification:
vim /etc/pam.d/vsftpdComment out the following line:
#auth required pam_shells.soThen log in again, it’s OK.
(4) check whether cat /etc/shells has your users
Check what the home directory of your login account corresponds to the login shell. Mine is /sbin/nologin user name: Password: user ID: group ID: annotative Description: Home Directory: login shell
cat /etc/passwd，
Check whether cat /etc/shells has your user’s home directory and login shell, without adding, saving and exiting.
cat /etc/shellsOpencv-3.4.13 is too new, and errors will be encountered during the compilation of kalibr. The summary is as follows:
Error 1: sudo pip install python-igraph –upgrade failed
Solution:
sudo apt-get install python-igraph
Error 2:
Could not find a package configuration file provided by “code_utils” with
any of the following names:
