AttributeError: ‘Settings’ object has no attribute ‘ROOT_ URLCONF’

If you encounter this problem. There are the following prerequisites,
1. You deploy with uwsgi + Django
2. You have modified the settings configuration file path, for example, create a dev.py file in a new place for configuration

Then you have to look at the configuration in uwsgi.ini. Whether the settings in the WSGI file is the configuration file you want.

[ABAP] sproxy opens ESR and reports an error has occurred during communication ESR

Recently, an error has occurred during communication ESR is reported by clicking sproxy → source → ESR when publishing the Po agent class. The following is the error message. Figure 1 shows the Chinese environment and Figure 2 shows the English environment:

Query SAP notes and try to solve the problem. It is found that the description of notes: 2957501 – an error has occurred during communication with ESR is consistent with the problem.

Sm59: SAP was checked step by step according to the method provided in notes_ PROXY_ ESR connection;

SPROX_ CHECK_ IFR_ CONNECTION -> Enterprise Services Builder data not understood
SPROX_ CHECK_ IFR_ ADDRESS -> Cannot determine Repository Version, An error has occurred during communication with ESR
SPROX_ CHECK_ IFR_ RESPONSE -> Requested Repository is down., An error has occurred during communication with ESR
SPROX_ CHECK_ HTTP_ COMMUNICATION -> HTTP communication functioning

The error report provided is consistent with the document, and the method provided in notes: 2370153 is used to solve the problem.

Solution: view sm59: SAP in Po_ PROXY_ The ESR service found that the Po account was locked, and the unlocked account sproxy returned to normal.

Extension: create/lock/unlock/modify password, etc. change the address of Po user:

  http://< server>:& lt; port>/ startPage   →   User Management

The CXX compiler identification is unknown CMake Error at CMakeLists.txt:11 (project):

Problem: when compiling GLOG 0.50, you should set the cross compiler. After setting the compiler, you will always report title errors. Enter the cross compiler on the Linux command line, but you can recognize the cross compiler;

The files for cross compiling are as follows:

the cross compiler can be recognized on the command line:

ubuntu0compile:~/glog-master/_build$ arm-linux-gnueabihf-g
arm-linux-gnueabihf-g++        arm-linux-gnueabihf-gcc-ar      arm-linux-gnueabihf-gcov        arm-linux-gnueabihf-gprof
arm-linux-gnueabihf-gcc         arm-linux-gnueabihf-gcc-nm      arm-linux-gnueabihf-gdb         
arm-linux-gnueabihf-gcc-4.9.4   arm-linux-gnueabihf-gcc-ranlib  arm-linux-gnueabihf-gfortran

However, the following errors are reported during compilation:

ubuntu0compile:~/glog-master$ sudo cmake -H. -B_build -DCMAKE_TOOLCHAIN_FILE="${PWD}/toolchains/gcc-cxx11-crosscompiling.cmake" && cd -
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:11 (project):
  The CMAKE_CXX_COMPILER:

    arm-linux-gnueabihf-g++

  is not a full path and was not found in the PATH.

  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.


-- Configuring incomplete, errors occurred!
See also "/home/glog-master/_build/CMakeFiles/CMakeOutput.log".
See also "/home/glog-master/_build/CMakeFiles/CMakeError.log".

The fundamental reason is that the cross compiler cannot be found. Under the path, only the directory of the cross compiler is set, either reset the environment variable, or set the path of the cross compiler to an absolute path; The problem is solved by setting the absolute path

The anaconda-navigator interface cannot be started, loading application, report ERROR download_api._get_url error

Anaconda3, which was originally installed, suddenly couldn’t be started today. It got stuck in the loading application interface. It was forced to uninstall and reinstall. The situation is the same. Errors are reported as follows:

C:\Users\ljw>anaconda-navigator

Expecting value: line 1 column 1 (char 0)

The reason is the same as the connection analysis above, mainly because the vscode address obtained by self._VSCODE_ENDPOINT in vscode_application_data() is wrong ( https://vscode-update.azurewebsites.net/api/update/win32-x64/stable/version ). As a result of the visit, the correct address is: https://update.code.visualstudio.com/api/update/win32-x64/stable/version

Solution: in Anaconda_ Search in api.py

        VSCODE_ENDPOINT = (
            'https://vscode-update.azurewebsites.net/api/update'
            '/{}/stable/version'.format(VSCODE_SUBDIR)
        )

Change the link to:

        VSCODE_ENDPOINT = (
            'https://update.code.visualstudio.com/api/update'
            '/{}/stable/version'.format(VSCODE_SUBDIR)
        )

Save the file and restart Anaconda navigator to solve the problem

Problem: error (24) file not found is prompted when importing the network table

A new PCB is created, and the following error is prompted when importing the network table:

  ERROR(24) File not found  

         Packager files not found

And

ERROR(102) Run stopped because errors were detected

This is because of the path problem. The path address in the red box below must be placed in the folder of the three files in the network table.
