First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
For GitHub Actions:
There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.
Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.

If you look at React without JSX, you'll see that the XML-inspired syntax (
) is just short for
Right now, if you renamed
MockComponent and tried using the angle bracket syntax, the first issue is that your function receives two arguments. React components are either class components that take one constructor argument (props) or functional components that take one argument (again, props). The second issue is that your function returns a React functional component, when it needs to return a rendered React element.
One way to fix this issue is to convert
mockComponent into a React functional component and make
propOverride props of the FC.
I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:
Error: Must use import to load ES Module

I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.
So, do this:
- In package.json, update the line
"@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
npm ifrom a terminal/command prompt in the folder
- In .eslintrc, update the parser line
- In .eslintrc, add
"requireConfigFile": false,to the parserOptions section (underneath
"ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
- Run the command to lint a file
Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.
In package.json file react-router-dom dependencies added. App component wrapped by BrowswerRouter , but when I wrap route by switch it says the following error Switch' is not exported from 'react-router-dom'. I deleted the package.json.lock ,node modules, installed npm again and npm install @babel/core --save. Still not working. I successfully wasted 6 hour for this. Can you please help me to fix this? why it's not importing?

Switchin react-router v6
You are using
react-router-dom version 6, which replaced Switch with the Routes component
When testing components with
s, for example in my answer to Recommended approach for route-based tests within routes of react-router, I often use the following pattern to get access to the current
location for testing purposes:

React Router v6 splits apart the history into multiple pieces, for this use case the relevant parts are the navigator and the location. This change is hinted at in Use
useNavigate instead of
useHistory, and you can see it in the definition of the
Navigator type used in the

It looks like you have defined custom paths in your TypeScript config (usually
import plugin doesn't know about the correct location of the TypeScript config and hence cannot resolve those paths. What you need to do, is to specify the correct path to your TypeScript config via the
project parameter in the resolver options:
After updating my npm packages, some of the imports from the 'vue' module started showing errors:
TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'
where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.
What I've tried:
- Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of
TypeError: Object(...) is not a functionerrors in console and not rendering the app at all. In the terminal, some new warnings are introduced:
"export 'X' (imported as '_X') was not found in 'vue'where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle.
- Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
- Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.

That named exports from composition API are unavailable means that
vue is Vue 2 at some place which has only default export. Since Vue 3 is in
dependencies and both lock file and
node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.
The problem needs to be investigated in lock file. It shows that
@email@example.com depends on
vue-jest@3 which depends on
A possible solution is to upgrade
@vue/cli-plugin-unit-jest to the latest version,
next. The same likely applies to other
@vue/cli-* packages because they have matching versions.
