failed: Error during WebSocket handshake: Unexpected response code: 200
Windows problem loadlibrary failed, GetLastError = 193
LoadLibrary A.dll failed, and GetLastError returns 193, %1 is not a valid Win32 application.
Maybe the b. DLL associated with a. DLL is not updated, such as a new DLL with a new interface (GetVersion) in the application, and the current B.DLL is not updated, resulting in a 193 error. The dynamically loaded library depends on other dynamic libraries, and you just replace the dynamically loaded library in the library, and the dynamic library dependent library is not updated.
There is also a problem with the 0xc000007b startup program: it is likely that the dependent library is in conflict (that is, the dependent library’s version may not be correct)

Internal error 2203 C:\windows\Installer
———————————————————————————————————————————-
The following error message appeared today when installing the software:
Internal error 2203 C:\windows\installer\1bbe2ab.ipi
// Screenshot below
I found the reason, it turned out that there was a problem with the environment variable of the user I logged in to the system. Strangely enough, the environment variable was the same when I installed it before
In this case, TEMP=I:\ TMP=I:\ // I is the disk character name
Change them back to:
TEMP=%USERPROFILE%/Local Settings/Temp
TMP=%USERPROFILE%/Local Settings/Temp
// Screenshot below
It is not clear why this problem did not occur when the TEMP and TMP paths were changed.
Invalid Drive:H:\ (subst X: %TEMP%)
——————————————————————————————————————
Sometimes you install software that displays an error message that says “Invalid Drive:H:\”, or it could be
Invalid Drive:D:\ Invalid Drive:F:\ etc
The screenshot is as follows:
—————————————————————————————————————————————
To solve the above problem, in CMD, type a command: subst H: %TEMP%
The screenshot is as follows:
———————————————————————————————————————————————–
The above command is to take the temporary path %TEMP% of the system as a partition H. After we install the software, we want to delete the newly created partition H.
How do you do that?Also execute the following command in CMD; Subst: H/D
—————————————————————————————————————————————————————-
Brief introduction to SUBST:
Using the Built-in Windows Subst.exe tool, you can simulate a path on any partition as a separate partition,
Using this tool, you can trick the installer into successfully installing the software.

React Error: Minified React error #119
Error: Minified React error #119; visit http://facebook.github.io/react/docs/error-decoder.html?invariant=119 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.
According to the console print, we can visit
http://facebook.github.io/react/docs/error-decoder.html?The page invariant=119 gets the following message:
The full text of the error you just encountered is:
addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).
Then check to see if the component in question USES the ref attribute outside of the render method. The problem I’m reporting here is the unexpected use of the ref attribute outside of the render method in the body center component of the create dialog.
debugging is hard, I have to say.
I hope I can help you.

*
* This can be set to anything, but default usage is:
*
* development
* testing
* production
*
* NOTE: If you change these, also change the error_reporting() code below

2, CI error log by default in the application/logs/log – [time]. PHP, log level, path, time format, etc., in the application/config/config. The PHP file Settings, the code is as follows:
/*
|--------------------------------------------------------------------------
| Error Logging Threshold
|--------------------------------------------------------------------------
|
| If you have enabled error logging, you can set an error threshold to
| determine what gets logged. Threshold options are:
| You can enable error logging by setting a threshold over zero. The

|
| 0 = Disables logging, Error logging TURNED OFF
| 1 = Error Messages (including PHP errors)
| 2 = Debug Messages
| 3 = Informational Messages
| 4 = All Messages
|
| For a live site you'll usually only enable Errors (1) to be logged otherwise

3, in their own code to log, you can call the global function log_message(‘ level ‘,’ message ‘), the level of parameters is (debug Debug, error error, information info), the content can be defined by themselves.
log_message('error', 'error message.');
log_message('debug', 'debug message.');
log_message('info', 'info message.');
When to enter success and error in AJAX
A quick introduction to Ajax:
Simply put, an Ajax request sends a request through an XMLHttpRequest object, which has four states (readyStates) :
0- uninitialized, 1- initializing, 2- sending data, 3- sending data, 4- done.
When XMLHttpRequest. ReadyState is 4, said ajax request has been completed can get the result.
Ajax’s success and Error methods are triggered based on the response status code. Success () is triggered when XMLHttprequest.status is 200, indicating a successful response. Other status codes trigger error().
In addition to the response status code, Ajax can also use an error method in the following situations:
- return data type is not JSON network interrupt background response interrupt

The solution
The exception is caused by 8000 port being occupied. Check the 8000 port being occupied under Windows
E:\Git\Repository\angular-phonecat>netstat -ano|findstr "8000"

Because process 0 is a system process, executing “Taskkill/PID 0” will not kill it. So, find another way to change the port, as follows:
Under node’s installation root, find package.json, search 8000, and replace with 8888
Then execute the command NPM Start from the command line, and it starts successfully
Enter it in the browser
http://localhost:8888
, you can see the successful access

A word of caution:
STD :: Dynamic_pointer_cast for dynamic conversion shared_PTR is the part in STD. This is also obvious because shared_PTR is a part in STD
