[Solved] keil2 Error: FATAL ERROR L210: I/O ERROR ON INPUT FILE

As shown in the figure: test is the name of the file, and the error message is displayed after * * *

FATAL ERROR L210

Solution: Google and download the file c51fps.lib, then find the Lib of your keil folder. For example, my address is: D:\Keil C51 v6.12\c5\LIB

Different versions may have different folder names. If you’re not sure, copy more and put them all.

Reason: This is the library of floating-point operation. The decimal KEIL2 download package is used. The library without decimal operation needs to be downloaded by yourself.

Stata Comment // Error / invalid name r(198); [How to Solve]

Stata common notes

Method 1: * enter * at the front of a single line to indicate the comment of this line
method 2:// enter anywhere in a single line.// the content after// is commented

Annotation usage scenario

For mode 1 *, you can use it in the command line or do file
for mode 2//, the error “/ invalid name R (198)” will be reported in the command line (as shown in the figure below), but it is completely normal to use it in the do file. So, there is a small concept of losing small difference!

[Solved] ECharts Console Error: `resize` should not be called during main process

When using ecarts, the console reports an error ` resize ` should not be called during main process

This situation may occur in the scenario where echarts is used in combination with Vue 3, especially after the echarts instance is wrapped with Ref.

This article is excerpted from another blog post, the use of echarts 5 in the development of Vue 3

1. Problem analysis

In general, the encapsulation of ecarts chart does not need to expose the ecarts object to the rendering context. If you do intend to declare an echots object as a response, use shallowref instead of ref:

// GOOD
const chart = shallowRef<echarts.ECharts>(); 

// BAD
const chart = ref<echarts.ECharts>();

If you do not use shallowref, the command line may report an error ‘resize’ should not be called during main process; In fact, any instance created by a third-party library should be processed responsively using shallowref instead of ref.

How to Solve Pycharm SQL Union Error

Question

Today, when writing MySQL code in pycharm, I always encounter errors when using Union. Although the syntax itself is correct, the red horizontal line is annoying

It’s just that you have to change union to union all to eliminate the error report.

Press setting -> editor-> Inspections, then find no data sources configured under the SQL on the right, and cancel all related to the red exclamation mark, but it is still fruitless.

However, inspired by the article, the reason for the problem is found in the location of the configuration database

Solution:

The configuration database is in file -> Settings -> Languages & Frameworks -> SQL conversations
the reason for the problem is that I configured the database before. At that time, Clickhouse was configured, which is different from MySQL in the usage of union,
so just change Clickhouse to MySQL.

before change

modified

This will return to normal~

R Language: How to Solve featureplot function Error

This kind of error occurs when you run the featureplot function and want to generate a scatter diagram using ellipses, but the image cannot be generated due to the lack of ellipsse package. The error code is

Error in grid.Call.graphics(C_downviewport, name$name, strict) : 
  Viewport 'plot_01.panel.1.1.off.vp' was not found

Solution: only install the ellipse package, not the library, and then rerun the previous featureplot function.

install.packages("ellipse")
