问题 In my project I have main file with global styles but also I use styles in a individual components. Nonetheless I use the same variables to pass font-size, colours to elements. I'm not an expert in React but I think that will be nice to move variables to separate file to don't repeat the code. How can I do this in a proper way? Global styles: 'use strict'; let React = require('react-native'); let { StyleSheet, } = React; let INIT_COLOR = "#fff"; let INIT_FONT_SIZE = 16; module.exports =

问题 I want to save the result of a psql query as an Excel file. ie, I have a table named company with 5 column. I want to execute the query, SELECT column_1, column_2, FROM company; And I just want to save the result of this query as a Excel file. Is it possible in PostgreSQL? If yes then please explain it.

问题 I'm looking for a way to export a yaml file from a deployed component but without the cluster specific information. kubectl get MYOBJECT --export -o yaml > my.yaml but since "export" is now deprecated (since 1.14 and should normally disappear in 1.18 (didn't find it in changelog), what would be an alternative ? thanks 回答1: There is no consistent way to do this since there is no overall guidelines about defaulting and other live data clean up. That is why it was deprecated. You should keep

问题 I am unable to make even the simplest export of variables, from within scripts, to work in my bash - what am I dooing wrong?
