Sina world of Warcraft 3.1.3 compressed package cannot be executed. Solution: failed to open archive interface.MPQ

this article only for wow. Exe execution “Failed to open archive interface.MPQ” prompt when the solution:

1. Create a new folder under wow. Exe and name it “Data”.

2. Move all.mpQ files in wow.exe folder to the “Data” folder;

3. Subfolder “eN??” in the folder where wow.exe resides. “(There are also MPQ files under this folder), move the entire folder under” Data “;

4. Execute wow. Exe, no more errors.

is because sina’s compression package is not volume compression, but a single separate compression, especially several large MPQ files separately compressed, changed the wow directory structure, as long as the structure can be restored to solve this problem.

but strange is, this method is not scientific, in addition after landing, will wow directory to see a strange account + number named file, after confirmation should be Trojan to log in the formation of the file. If in order to prevent security, we suggest that the client to disconnect the network strictly check the virus.

last word, sina is not kind!

RTR3InitEx failed with rc=-1912 (rc=-1912)

main reason: having installed virtualbox before, there are multiple virtualboxes in the system. You can uninstall all virtualboxes first, and then install

sudo apt-get autoremove 'virtualbox*'

2. Reinstall:

sudo DPKG -i virtualbox – 5.2 _5. 2.6-120293 ~ Ubuntu ~ xenial_amd64. Deb

solution 2:

configure DNS resolution to 114.114.114.114

Solve the problem of copy failed: stat / var / lib / docker / TMP / docker builder 455335933 / opt: no such file or directory

1. Error reporting

2. Dockerfile file

3. The reasons for

Dockerfile lines beginning with # are treated as comments. If a # comment is used after a valid instruction, it will be treated as a parameter, resulting in an error

4. Solution: just remove the comment, or put the comment on a separate line

Error: request failed with status code 500

in projects where the front and back ends are separated

the front end USES a post request to send data to the back end, but an error occurs:

Error: Request failed with status code 500 Error

we need to know that 500 represents (server internal error) the server encountered an error and was unable to complete the request.

take a look at my original part of the code:

front-end request:

back-end receiving entity and control layer code:

if you look closely, you will see that the parameter names that my front end took when I sent the request were userName and password

but the back end used username and password to receive the parameters from the front end, so I changed the front end username — > username

finally OK! If you have the same problem, check to see if the parameters you sent are the same as the parameters you received, otherwise the parameters will be empty

Finished with error: Gradle task assembleDebug failed with exit code 1

recently encountered the following bug during development with flutter :

during run,

Finished with error: Gradle task assembleDebug failed with exit code 1

at this point if you are in a hurry to pack for someone else, you can scan with flutter clean and then re-run. The first time always succeeds,

then, after the first run, the error will continue.

you can’t just flutter clean all the time and then run, that would be a waste of time, not a long-term solution.

———————————————–

according to the above line of error Google has encountered many similar situations, but the reasons for the error are different, and I did not see the possibility of

is the same reason that I’m in this situation,

———————

but the answer is that running the flutter run-v will give you more detailed information about the error, but still not much use.

the information obtained from the flutter run-v does not locate the cause of the error.

flutter as a new cross-platform solution is really a pitfall, but the problem will always be solved and the project will continue to be done,

————–

then began to think, until the day before yesterday off work or not this situation, yesterday since noon had this problem, so

Can

find clues in git’s commit records?

——————————–

then starts to look through the Git commit record of this period and finds a suspicious 

import 'package:inin/features/searchpage/SearchUserPage.dart%20';

Is there an extra %20 after

?

————————

so delete this line, flutter clean, re-run, the problem finally does not appear.

solved the case…

Idapython: the solution of importing “site” failed error

0 x00 background

suddenly one day IDA6.8 opens and prompt idapython error:
message:

0x01 problem cause

IDA website has an explanation for this problem:

This issue is usually caused by presence of non-standard python27.dll
in the PATH which uses its own set of modules (you should edit PATH in
this case). However, it may happen if your Python installation is
broken in some way. Reinstalling Python manually may fix it.

The general reason for

is that your host’s environment variable path contains the non-standard python27.dll, and, of course, it may also be due to an unexpected terminal during an installation. Manually reinstalling Python may fix this problem.

0x02 problem fix

official also kindly give detailed repair method:

  1. view python27. DLL location 
    c:\>where python27.dll
    C:\Windows\System32\python27.dll
  1. view in the registry HKEY_LOCAL_MACHINE\SOFTWARE\Python 2.7\InstallPath the value is python2.7’s installation path
  2. adding an environment variable with the key PYTHONHOME and the value is Python’s installation path.
  3. if idapython was loaded normally but this error still exists, print sys.path to determine if it is as expected 
Python>import sys
Python>sys.path
['C:\\Windows\\system32\\python27.zip', 'C:\\Python27-x64\\Lib', 'C:\\Python27-x64\\DLLs', 'C:\\Python27-x64\\Lib\\lib-tk', 'C:\\Program Files\\IDA 7.0\\python', 'C:\\Python27-x64', 'C:\\Python27-x64\\lib\\site-packages', 'C:\\Program Files\\IDA 7.0\\python\\lib\\python2.7\\lib-dynload\\ida_32', 'C:\\Program Files\\IDA 7.0\\python']
  1. tracks the loading process of IDAPython module. Set the environment variable PYTHONVERBOSE=1 before IDA runs, and the path path will be printed out (or add -l to the IDA run command to generate the log file).

0x03 problem solved

using the third step, creating an environment variable PYTHONHOME will solve my current problem.

is the pitfall of some blog that creates the environment variable %PYTHONHOME%. What the hell is that?

in the context of environment variables, %path% means that path is a defined call to an environment variable, equivalent to $path in Linux. The first time you define a variable, you don’t use %%.
