Vue packages version mismatch:
- [email protected] (G:\workspace\BookShopManageVue\node_modules\vue\dist\vue.runtime.common.js)
- [email protected] (G:\workspace\BookShopManageVue\node_modules\[email protected]@ ;vue-template-compiler\package.json)
This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template- compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.
version problems,
The currently installed VUE dependency node_modules is version 2.6.14, but the imported project uses version 2.7.10.
Just unify the two versions.
Hint: how to unify versions. Is to download and install version 2.6.14. Still version 2.7.10?
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
Check the version of vue loader in package-lock.json. My vue loader version is higher than 10. So I’m going to unity 1.6.14 version. (I didn’t see vue loader directly download and install version 2.7.10 before. The result is the same error)
npm install [email protected] --save (Need to check the version)
Today I packaged the APK on my mobile phone and found that I couldn’t enter the main page, and it kept prompting

I checked several methods but couldn’t use it. Finally, I changed the compilation settings to solve the problem.
Changed to ARMv7 as shown in the figure and it will be normal. If ARM64 is needed, it can be solved elsewhere.
Now this is the case. The package is delivered normally, record it
The following error occurred during the first SSH connection and GIT operation：

Suddenly reported an error after running，It doesn’t work whether it is uninstalled and then installed
I suddenly thought about whether the version is too high or not
Update the specified version in the package manager, I will update to the next-level version and the problem will be solved.
In the process of learning Linux embedded development, I encountered the following problems: after installing VS code in the Ubuntu virtual machine, it need to install appropriate plug-ins. At this point, vscode fails to expand XHR Failed, as shown in the figure:
And press the F1 key inside Vs code to open Developer:Toggle Developer Tools, enter the Console to query the reason, The error shown in the figure below appears (That is, Ubuntu system will point the domain name to the specified IP solve this problem):
After searching the Internet for many solutions, the following operations can solve the problem:
1. Open the hosts file in the Ubuntu terminal
sudo gedit /etc/hosts2. Add the corresponding relationship between IP and domain name in the file as follows, and save the hosts file：

Problem:
I have written some code based on Hikvision’s sdk for controlling the camera. One section of the program is mainly used to get NVR channel configuration information
The codes is as below:
I use the function NET_DVR_GetDVRConfig
#include #include "HCNetSDK.h" int main() { NET_DVR_Init(); //Set connection time and reconnect time NET_DVR_SetConnectTime(2000, 1); NET_DVR_SetReconnect(10000, true); // 注册设备 LONG lUserID; //Login parameters, including device address, login user, password, etc. NET_DVR_USER_LOGIN_INFO struLoginInfo = { 0 }; struLoginInfo.bUseAsynLogin = 0; //同步登录方式 strcpy(struLoginInfo.sDeviceAddress, "192.168.20.106"); //设备IP地址 struLoginInfo.wPort = 8000; //设备服务端口 strcpy(struLoginInfo.sUserName, "admin"); //设备登录用户名 strcpy(struLoginInfo.sPassword, "111111hk"); //设备登录密码 //设备信息, 输出参数 NET_DVR_DEVICEINFO_V40 struDeviceInfoV40 = { 0 }; lUserID = NET_DVR_Login_V40(&struLoginInfo, &struDeviceInfoV40); if (lUserID < 0) { printf("Login failed, error code: %d\n", NET_DVR_GetLastError()); NET_DVR_Cleanup(); return -1; } NET_DVR_IPPARACFG_V40 ipcfg; DWORD bytesReturned = 0; ipcfg.dwSize = sizeof(NET_DVR_IPPARACFG_V40); int iGroupNO = 0; bool resCode = NET_DVR_GetDVRConfig(lUserID, NET_DVR_GET_IPPARACFG_V40, iGroupNO, &ipcfg, sizeof(NET_DVR_IPPARACFG_V40), &bytesReturned); if (! resCode) { DWORD code = NET_DVR_GetLastError(); std::cout << "NET_DVR_GetDVRConfig failed " << NET_DVR_GetErrorMsg((LONG*)(&code)) << std::endl; NET_DVR_Logout(lUserID); NET_DVR_Cleanup(); return -1; } std::cout << "设备组 " << ipcfg.dwGroupNum << " 数字通道个数 " << ipcfg.dwDChanNum << " 起始通道 " << ipcfg.dwStartDChan << std::endl << std::endl; for (int i = 0; i < ipcfg.dwDChanNum; i++) { NET_DVR_PICCFG_V30 channelInfo; bytesReturned = 0; channelInfo.dwSize = sizeof(NET_DVR_PICCFG_V30); int channelNum = i + ipcfg.dwStartDChan; NET_DVR_GetDVRConfig(lUserID, NET_DVR_GET_PICCFG_V30, channelNum, &channelInfo, sizeof(NET_DVR_PICCFG_V30), &bytesReturned); std::cout <<"通道号 "<< channelNum << "\t通道名称 " << channelInfo.sChanName; std::cout << "\t用户名 " << ipcfg.struIPDevInfo[i].sUserName << "\t密码 " << ipcfg.struIPDevInfo[i].sPassword; std::cout << "\t设备ID " << (int)ipcfg.struIPDevInfo[i].szDeviceID; std::cout << "\tip地址 " << ipcfg.struIPDevInfo[i].struIP.sIpV4 << "\t端口 " << ipcfg.struIPDevInfo[i].wDVRPort << std::endl; } //释放SDK资源 NET_DVR_Logout(lUserID); NET_DVR_Cleanup(); return 0; } The code was running ok, but when migrating to another machine, something went wrong.
Report the error: NET_DVR_GetDVRConfig failed Device does not support this function
Note the phrase:
If the number of IP channels supported by the device is greater than 0, then the remote parameter configuration interface NET_DVR_GetDVRConfig can be used.
This means that to use this function, you need to check the number of IP channels supported by the device first.
Also, the manual gives a sample program (check first, then call)
The sample procedure is as follows.
ps: there is a point I want to spit, the manual on the ET_DVR_GetDVRConfig function explanation, there is no mention of this issue, causing me to look for a long time to find here to write. Since this function is not supported by all devices, then the norm should be written to check first, then call.
