How to Solve Mac installation luajit error

Install luajit today. After downloading the file, run the mak é command and keep reporting this error

tips on the official website:
note for OSX: if the MacOSX_ DEPLOYMENT_ TARGET environment variable is not set, then it’s forced to 10.4.

So the solution: set the environment variable

export MACOSX_DEPLOYMENT_TARGET=10.15

If the error is still reported, it may be that there is no package of 10.15 locally. Replace 10.15 with the version of the cost machine SDK. To see the SDK version of this machine, run the following command:

cd /Library/Developer/CommandLineTools/SDKs

Error reporting reason

Because the Hadoop version loaded at runtime is version 3.2, while the Hadoop version in the cluster is version 3.0.0-cdh6.3.2
this code is different for two different versions

Solution:

Download the spark source code, compile spark by yourself, and change the built-in Hadoop to version 3.0.0-cdh6.3.2

Pyqt5 Error: AttributeError: ‘QWidget‘ object has no attribute ‘setCentralWidget‘

problem

AttributeError: 'QWidget' object has no attribute 'setCentralWidget'

reason

We can see setcentralwidget in QT help document that it belongs to the method of qmainwindow class and is defined separately in its class, so it cannot be called directly for its parent class QWidget.

void QMainWindow::setCentralWidget(QWidget *widget)

decided

Write QtWidgets.QWidget() converts QtWidgets.QMainWindow().

How to Solve Git Error: error: failed to push some refs to……

Error message:

error: failed to push some refs to '[email protected]:....." Updates were rejected because the remote contains work that you do not have locally.
This is usually caused by another repository pushing to

Cause analysis:

1. This error may occur when using git to push the source code to GitHub

2. The main reason for the error is that the readme.md file in GitHub is not in the local code directory

Solutiont:

Method 1: pull it down first and it will merge automatically (don’t worry)

Command: git pull origin master

Method 2: Code merging can be carried out through the following commands

Command: git pull — rebase origin master (my successful solution is method 2)

Finally, execute the statement git push to upload the code to GitHub

Command: git push – U origin master

[Solved] Error from server (InternalError): an error on the server (““) has prevented the request from suc

Phenomenon

This error occurs when executing any k8s command

[root@master helm]# kubectl get pod
Error from server (InternalError): an error on the server ("") has prevented the request from succeeding

reason

To contact apiserver, you need to visit: https://master:6443

The current command is executed directly on the control plane, so it is necessary to ensure that there is no problem in the resolution of Master 

# Since the http proxy was previously configured on the local machine
export http_proxy='http://10.0.0.1:8889'
export https_proxy='http://10.0.0.1:8889'

# and
[root@master helm]# hostname
master

Therefore, the resolution of Master is local and will be proxy to http://10.0.0.1:8889

Therefore, the apiserver cannot be accessed normally

Solution:

Method 1: cancel the agent

unset http_proxy
unset https_proxy

Method 2: do not proxy this machine

export no_proxy='master,localhost,127.0.0.1,localaddress,.localdomain.com'

Note: if it is not restored after modification, you can try to restart the kubelet service of the node.

Problem description

Some time ago, I started a small smart home project to practice my hand. I encountered this problem when compiling

Compilation error:

reason:

The function pointer in the structure element is incorrectly defined

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <wiringSerial.h>

struct Command{
        char cmdName[128];
        char cmd[32];
        int (*init)();		//int init();
        int (*getCmd)(struct Command *voice);	//int getCmd(struct Command *voice);
        char log[1024];
        int fd;
        struct Command *next;

Aapt Remove Command error during crunch – archive is toast

To package APK these days, you need to use the AAPT command to remove the old certificate file in APK, add a new certificate file again, and then sign and repackage again. It is found that when using the AAPT remove command, the error during crash – archive is toast is always reported. After a day’s comparison, it is found that it is related to the referenced com.android.tools.build: gradle: 4.1.1 and gradle-6.5-bin versions. As long as it is equal to or greater than this version, this error will be reported, which should be a bug of AAPT.

Solution:

1. The gradle plug-in is lower than these two versions. It’s unrealistic. It’s impossible not to upgrade it all the time.

2. Since APK is essentially a zip file, simply when deleting the file, open the APK package directly with the zip decompression software, manually delete the ball, and complete the remaining AAPT add command and re signature operation with the command line.

[Solved] CMake Error: Could not create named generator Visual Studio 16 2019

Cmake error: could not create named generator visual studio 16 2019

When running the demo in openvino, this bug is always prompted. According to the suggestions of stackoverflow and official documents, use cmake - G "Visual Studio 16 2019" - a x64 this command to compile, which is also invalid. Later, after troubleshooting, I thought it might be the problem of cmake version. Because the old version of cmake (before 3.14) may not find the latest visual studio, I went to the official website to download it, Run the. Bat file in the demo to solve the problem
