Error 4

The is shown in figure 1:

Google, the unified answer is because memory is not enough , free looked at the system memory usage, it was really occupied. Since the device is the company’s uniform compilation platform (used by several colleagues), this is not surprising. As shown in figure 2:

figure 2 free – h details

can be solved by the following solution:
(1) sudo dd if=/dev/zero of=/swapfile bs=64M count=16 (the size of count is the size of the increased swap space, 64M is the block size, So the space size is bs*count=1024MB)
(2)sudo mkswap /swapfile (format the space just now as swap format) (3)sudo swapon /swapfile (use the swap space just created)

Solution:
this is because the current version of [email protected] does not support [email protected]. So simply delete the current Webpack-dev-Server folder and reinstall the higher version. The steps are as follows:

    find the project folder you created, mine is D:\javaProject\vue\myvue\node_modules\webpack-dev-server, delete the webpack-dev-server folder. Run NPM I [email protected] in the current project directory, and your webpack-dev-server version will be fine. Or update directly to the latest version 
npm i –-save-dev webpack-dev-server@next

13. R language: Error in match.names(clabs, names(xi)): The name is not relative to the original name

Problem description

Count_bind = rbind(count_left,count_right)
Error in match.names(clabs, names(xi)) : names are not relative to existing names

To explore the reason
This is a problem in the match.names function that occurs during rbind, for the simple reason that my first two objects to be rbind have different column names:


To solve the problem
Manually changing the column name can solve the problem:

colnames(count_left) <- c("AAA")

Use the above function to execute the two objects separately, and just change the column name.
Big mouth a
I’ve never really understood why data.frame cannot set the column name when declared but can set the row name. Below is the official usage, only for row row.

The data frame (… , row.names = NULL, check.rows = FALSE,
check.names = TRUE, fix.empty.names = TRUE,
stringsAsFactors = default.stringsAsFactors())

In this way, I often have to manually name the column names of the data box. Usually, the code I write is genetic data, so as to ensure the accuracy of the column names. However, it would be troublesome to write small codes for statistics
