How to Solve Tabbarview error in Column 2021

reason

The tabbarviewcomponent occupies as much space as the parent component. Generally, the outer layer of this layout is scrollable, similar to singlechildscrollview, but there is no clear height constraint in the column, that is, infinite height, so an error is reported.

Solution:

1. Fixed height

It directly solves the problem locally, but there is a big disadvantage. The components loaded by tabbarview may have different heights, so the predetermined height should be their maximum height, and the layout is not good-looking.

SingleChildScrollView(
  child: Column(
    children: [
      MyTabBar(),
     SizedBox(
     	height: 500,
    	child: TabBarView(
    		children:[
  				MyTabView1(),
  				MyTabView2(),
    		],
    	),
     ),
    ],
  ),
)

2. Do not use the tabbarview component

It is recommended to use the indexedstack component instead. The disadvantage is that it lacks the sliding animation of the original tabbarview component, but it can be customized with the animatedswitcher component. Click to learn more

SingleChildScrollView(
  child: Column(
    children: [
      MyTabBar(),
      IndexedStack(
      	index: currentIndex, //currentIndex is the value of my example, in reality it may come from TabController, or Provider, etc.
      	children:[
      		MyTabView1(),
  			MyTabView2(),
      	],
      ),
     ),
    ],
  ),
)

Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

Troubleshooting process

First confirm the compatibility between non-springboot and ES version
and then check whether @bean is configured

Finally, problems are found

[Solved] Pytest Error: E ModuleNotFoundError: No module named ‘common

Hint: make sure your test modules/packages have valid Python names. Pytest error

Solution:

Method 1: Create a new conftest.py file in the root directory where you want to execute pytest; the contents of the file

import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '. ')))

Method 2: pyteset contains __init__.py files in each directory under the test case directory; execute it in the project’s follow directory, which is also possible, as tested

Git push origin XXX error proxy connect aborted

Let’s first analyze the problem. The error prompt is obvious. The proxy connection is aborted. What causes it
at the beginning, without saying a word, baidu directly. After various operations, cancel the agent, set the agent, cancel again, and try again?It’s useless. It still reports an error, but the initial timeout error has become proxy connect aborted
it’s hard for me. I’ve been working all day. When it’s time to submit, give me the whole deal?Is this the law that problems must happen before work. Hey, I can’t continue the whole process. I’ve seen various methods on the Internet. The original solution is as follows:

It turns out that there is no separate proxy configured for GIT. Configure proxy for git:
git config — global http.proxy‘ http://127.0.0.1:1087 ’
git config –global https.proxy ‘ socks://127.0.0.1:1080 ’

However, I’m sorry, it’s no use. It’s still wrong. But this operation reminds me that I haven’t checked the GIT configuration of my own project.

Solution:

Next is the moment to witness miracles

    1. first open the file where your project is located.

    1. of course, if you can’t see it after opening the project, don’t panic. Open the folder where your project is located, and then click the view – Show – hide project above. Of course, this is win11. The old version is almost the same.

      1. then let’s go to the. Git folder, open the config configuration file, delete the proxy address, push again, and finish the work.

How to Solve Macbookm1 pod error 

Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "ZLPhotoBrowser":
  In snapshot (Podfile.lock):
    ZLPhotoBrowser (= 4.1.5)

  In Podfile:
    images_picker (from `.symlinks/plugins/images_picker/ios`) was resolved to 0.0.1, which depends on
      ZLPhotoBrowser (= 4.1.9)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `ZLPhotoBrowser` inside your development pod `images_picker`.
   You should run `pod update ZLPhotoBrowser` to apply changes you've made.

Solution:

sudo arch -x86_64 gem install ffi

arch -x86_64 pod install
//Prompt for pod update ZLPhotoBrowser uses the arch -x86_64 pod to update
arch -x86_64 pod update ZLPhotoBrowser
