[Solved] error [email protected]: The engine “node” is incompatible with this module.

Leave a reply

An error was reported when initializing the react project:

error [email protected]: The engine “node” is incompatible with this module. Expected version “^6.14.0 || ^8.10.0 || >=9.10.0”. Got “8.9.4”
error Found incompatible module
info Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.

This is caused by the incompatibility of the node version. Upgrading the node version can solve it, or it can be solved without upgrading. Use the following command:

npx create-react-app my-app  --use-npm

 

Official issues: https://github.com/facebook/create-react-app/issues/5714 and https://github.com/facebook/create-react-app/issues/3974

problem:

Guys, a few days ago, I installed `yarn` on my Mac just because it’s necessary for a project where I’m involved.

My problem is that, now, when I create a new app with `CRA`, it’s going to use `yarn` instead of `npm`. And, to be honest, I prefer `npm`.

Is there a way to force to use `npm` instead of `yarn`?
Or should I wait until finish the initial setup, then remove the `yarn.lock` file, the `node_modules` folder and then run `npm i`?

answer:

You can run CRA with `–use-npm` flag to force it to use npm.

[Solved] Hadoop Mapreduce Error: GC overhead limit exceeded

From the exception, we can see that when reduce reads the next data, there is a problem of insufficient memory. From the code, I found that the reduce side uses a read map set, which will cause the problem of insufficient memory. In hadoop2.x, the default container’s yarn child jvm heap size is 200M, which is specified by the parameter mapred.child.java.opts, which can be given when the job is submitted. It is a client-side effective parameter, which is configured in mapred-site. In the xml file, by modifying the parameter to -Xms200m -Xmx1000m to change the jvm heap size, the exception is resolved.

parameter name Defaults description
mapred.child.java.opts -Xmx200m Define the execution jvm parameters of the container container executed by mapreduce
mapred.map.child.java.opts Separately specify the execution jvm parameters of the map phase
mapred.reduce.child.java.opts Separately specify the execution jvm parameters of the reduce phase
mapreduce.admin.map.child.java.opts
-Djava.net.preferIPv4Stack=true -Dhadoop.metrics.log.level=WARN
 The administrator specifies the jvm parameters executed in the map phase
mapreduce.admin.reduce.child.java.opts
-Djava.net.preferIPv4Stack=true -Dhadoop.metrics.log.level=WARN
 The administrator specifies the execution jvm parameters of the reduce phase

 

 The respective execution order of the above five parameters taking effect is:

map stage: mapreduce.admin.map.child.java.opts <mapred.child.java.opts <mapred.map.child.java.opts, which means that the definition of mapred.map.child.java.opts will be used eventually jvm parameters, if there is a conflict.

Reduce phase: mapreduce.admin.reduce.child.java.opts <mapred.child.java.opts <mapred.reduce.child.java.opts

K8s Install Error: Error: unknown flag: –experimental-upload-certs

When installing the k8sV1.16 version today, the execution suddenly found that the command was wrong. It was possible to install V1.15 before, which may be the reason for the version upgrade.

Solution:

[root@k8s-master opt]# kubeadm init --config=kubeadm-config.yaml --experimental-upload-certs | tee kubeadm-init.log

Error: Failure while executing; tar --extract --no-same-owner --file /Users/wangchuangyan/Library/Caches/Homebrew/downloads/01840f175b09e7eb3d4ca7f11492bb1bee74fa7569a41a884c7ffb3418e11a02--libuv-1.41.0.catalina.bottle.tar.gz --directory /private/tmp/d20210708-6134-w2f3oo exited with

1. Here’s the output:
tar: Error opening archive: Failed to open ‘/Users/wangchuangyan/Library/Caches/Homebrew/downloads/01840f175b09e7eb3d4ca7f11492bb1bee74fa7569a41a884c7ffb3418e11a02–libuv-1.41.0.catalina.bottle.tar.gz’
It means that the libuv file cannot be opened
Solution: manually install brew install libuv

How to Solve Cocoapods Installation Failure

The scene appears

Recently, I replaced a 512 large hard disk and re installed MacOS 10.15. When installing cocoapods, the following error occurred

Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

Solution:

    1. it may be the problem of system version, which is not compatible with the latest version, so install the old version directly. I encountered the problem is 2021.07.06, the latest version is 1.10.1, find a 1.9.32020.05 release, should be compatible with 10.15
# Specify version to install
sudo gem install -n /usr/local/bin cocoapods -v 1.9.3
      1. use brew to install
brew install cocoapods

Vue3 Warning: [Vue warn]: Extraneous non-emits event listeners (changeParentProps) were passed to component

The following warning is reported in component communication (child to parent) in Vue3.
[Vue warn]: Extraneous non-emits event listeners (changeParentProps) were passed to component but could not be automatically inherited because component renders fragment or text root nodes. If the listener is intended to be a component custom event listener only, declare it using the “emits” option.

Solution: Just declare the custom event name

emits: [‘changeParentProps’]

<template>
  <div>
    Subcomponents
  </div>
  <button @click="changeParentProps"> Changes the parent component's passed props</button>
</template>
<script lang="ts">
import { defineComponent } from '@vue/composition-api'
export default defineComponent({
  emits: ['changeParentProps'],
  props: {
    data: {
      type: String,
      default: ''
    }
  },
  setup (props, { emit }) {
    // console.log(props)
    const changeParentProps = () => {
      emit('changeParentProps', '123')
    }
    return {
      changeParentProps
    }
  }
})
