Use in vue3:
var jweixin = require('jweixin-module');
It will be compiled with the error: require is not defined, there is no require module, change to import, because jweixin-module does not support export writing, so the introduction can not succeed.
Solution:
Use a third-party wrapper jdk: weixin-js-sdk
npm install weixin-js-sdk -S
import jweixin from 'weixin-js-sdk'

File "D:\Windows_DL_Environment\anaconda3\envs\py37\lib\site-packages\PIL\ImageFont.py", line 852, in freetype
return FreeTypeFont(font, size, index, encoding, layout_engine)
File "D:\Windows_DL_Environment\anaconda3\envs\py37\lib\site-packages\PIL\ImageFont.py", line 212, in __init__
font, size, index, encoding, layout_engine=layout_engine
OSError: cannot open resource
This class is a common font problem. In Windows environment, fonts are generally located in the C:\windows\fonts folder. In this folder, users can check whether the font specified in the python program exists.
fnt = ImageFont.truetype('Pillow/Tests/fonts/FreeMono.ttf', 50)
Solution 1:
Change the font that exists on the computer
ImageFont.truetype("Pillow/Tests/fonts/arial.ttf", 50)
Solution 2:
Found no freemono in the computer Ttf font, so you need to download
https://fontmeme.com/ziti/freemono-font/
After downloading, unzip it into the fonts folder
finally. Restart the computer to execute.
The C++ version in the CMakeLists for direct download of the A-LOAM library is 11, as follows:
cmake_minimum_required(VERSION 2.8.3)
project(aloam_velodyne)
set(CMAKE_BUILD_TYPE "Release")
set(CMAKE_CXX_FLAGS "-std=c++11")
set(CMAKE_CXX_FLAGS_RELEASE "-O3 -Wall -g")
But Ceres 2.0 and above requires C++14 compiler, so you just need to change the C++ compiler to 14
cmake_minimum_required(VERSION 2.8.3)
project(aloam_velodyne)
set(CMAKE_BUILD_TYPE "Release")
set(CMAKE_CXX_FLAGS "-std=c++14")
set(CMAKE_CXX_FLAGS_RELEASE "-O3 -Wall -g")

If you get the error Creating mailbox file: File exists when you add a user with useradd under linux
It is possible that userdel xxx did not add -r when deleting the user, so only the user was deleted, but not the user’s configuration file

I encountered a small problem when running m_gshhs_i after installing High Precision Shoreline GSHHS
First, review the installation method:
Step1:
Download GSHHS coastlines and WDBII rivers/borders in native binary format （ zip archive ）‘gshhs+wdbii_2.2.0.zip’ from http://www.soest.Hawaii.edu/pwessel/gshhs/Step 2:
unzip the zip file to the (……\MATLAB\toolbox\m_map\private) path
If there is no problem using m_gshhs_i in matlab after the above two steps, then there is no need to perform the operation and just use it normally. If the error is reported using m_gshhs_i as follows.
WARNING: Coastline file private/gshhs_i.b not found \n(Have you installed it?See the M_Map User's Guide for details)\n ---Using default coastline instead
Then we need to go to ……\MATLAB\toolbox\m_map\path to find the m_gshhs.m file, open it and find
FILNAME='private/gshhs_i.b';
Modify it with:
FILNAME='private\';
After saving, use m_gshhs_i again and find that it works fine. If it does not work properly after modification, then try modifying it to
FILNAME='The path to matlab on your computer\MATLAB\toolbox\m_map\private\';
At this time, it can be used normally m_gshhs_i.
Reason: no servlet-api.jar package

Today when I use pycharm again, the problem of frames are not available after setting the menu bar File->Settings->Editor->File Encodings
Modify Project Encodind to UTF-8, but still not, then menu bar File->Settings->Build,Execution,Deployment->Python Debugger
I unchecked PyQt compatible, but it didn’t work. Finally, I hit a few more breakpoints on the code to solve the problem.
