Hello I am a beginner in React-native and below is my flowconfig file's version and I get an error with this version
[version]
^0.92.0
Is there a way to fix this error, I was trying to run debug mode in visual code for running react-native projects and to print console.log.
So far I am unsuccessful.
PS:- beginner in react-native
Change [version] in the .flowconfig to match the installed version, ^0.95.1
1. Check that the following tags match
package.json
"devDependencies": {
"flow-bin": "0.130.0"
}
.flowconfig
[version]
^0.130.0
2. Clean & Reinstall
If they match, this error can occur when your node_modules are out of sync with the version of flow-bin in your package.json. This can occur if you've changed branches recently or have have an older version in your node modules.
Try removing and reinstalling like this:
rm -rf node_modules/ && npm i
Instead of changing the flow version make it a ranged version. For example something like >=0.50.0 or simply remove the version altogether. You can read about that more in the flowconfig docs
I find that changing the flow version every time you face this problem to be a bad approach especially if you work with a team and each team member has a different version installed and they would commit their version into the .flowconfig file

I upgraded my router-flux version 0.27 to 0.30.
I am facing error of evaluating addListner I also submit it in the issue
4.0.0-beta.30 is broken as the last commit says
update dependencies, bump version - don't use, errors are possible!
4.0.0-beta.28 is broken too. Use 4.0.0-beta.27 instead.
In package.json, make sure you have exactly this:
"react-native-router-flux": "4.0.0-beta.27"
Don't include ^ otherwise your package manager will still install the .28 version (unless you have a yarn.lock at .27).
So I've been working on a Vue.js project for couple times now, and I am facing a problem I've never seen before.
Trying to git pull the project on another computer, or even downloading the project as a zip file, when it's time to npm install, vue-material module fails and the whole thing cannot be run.
It goes this way, with vie-material :
vue-material#1.0.0 postinstall C:\<my_things>\node_modules\vue-material
sh build/git-hooks/install.sh
Then I see this :
/usr/bin/bash: build/git-hooks/install.sh: No such file or directory
Then the modules' tree shows in the terminal, and at the end, I can see all the errors related to vue-material, with this statement :
Tell the author that this fails on your system:
sh build/git-hooks/install.sh
By the way, I tried to crate a brand new Vue project, and tried to add vue-material inside, no problem, so it has to do with my project.
Obviously though, /usr/bin/bash does not exist, since I'm running Windows 10.
Any knowledge on npm's installing routine ? I'm out of solution to try...
Can you share your package.json file?
I had this same problem just now and found that NPM could possibly be installing the incorrect version. Where I had "^vue-material": "1.0.0-beta-7" NPM was installing version 1.0.0 instead of 1.0.0-beta-7. If you remove the ^ then it may work for you. This is where I found the answer that helped me.
https://github.com/vuematerial/vue-material/issues/1155
Well, after couple times figuring out what was wrong, I got this :
I tried to use yarn and it told me that my node version was too old (vue-material needed 7.0+ and my node was 6.9, or at least that is what yarn told me), so I got myself the 8.9.3 node.
After this I tried to use yarn again, and the error with that bash script showed again.... then I just tried to use npm install again, and it worked just fine...
I don't know about the bash script thing, but one thing to remember is to always check for node and npm's version when errors happend.... (and yarn looks very cool and simple imo ^^).
You kinda made me think about a version problem though, I got you that ! :D
Problem solved....
I've googled many sites but cannot found a tutorial that actually works for react-native + flow type.
There was flow installation guide from react-native#0.22 document, but it's gone in react-native#0.46.
However, it comes up again in Running Tests and Contributing, I tested to run npm run flow but not working, and yet it doesn't say how to make it works. It's possibly been a missing part inside of react-native documentation.
What I need is to run flow correctly with react-native. Auto-check flow every time I reload the page with ⌘R would be the best.
I just finished covering half of our project by flow and we use RN 0.44.0.
The tricky part is: do you also want to know errors inside node_modules, someone says those errors are helpful.
Anyway, I disable the error in node_modules, and here is my .flowconfig:
[ignore]
<PROJECT_ROOT>/node_modules/.*
<PROJECT_ROOT>/flowLibs.js
.....
[include]
[libs]
./flowLibs.js
.....
[lints]
[options]
You should install flow first if you not setup correctly,
npm install --save-dev flow-bin
and also run this in you project root after install:
npm run flow init
If npm run flow init does not work, just add "flow": "flow" in npm scripts.
After init, put my .flowconfig in your project .flowconfig file.
Then create a js file flowLibs.js and if npm run flow check cause your any error like Module_Name. Required module not found
Write down code in flowLibs.js:
declare module 'Module_Name' { declare var exports: any; };
After that, you should be good to go with you project now.
BTW, don't forget add //#flow on the top of the file which you want to check type.
I found flowtype is built in with react-native#0.46+.
For react-native document, I think they should at least tell flowtype is already built in. And for the rest document ex: Testing Your Changes#flow, it won't work without flow-bin, they should mention that too.
To make flowtype of best use, I use it with Visual Studio Code.
Steps:
Install flow-bin globally, by npm i flow-bin -g.
Make sure your terminal is responsive to command flow.
Install vscode flow extension.
Set vscode workspace preference with "javascript.validate.enable": false, to disable default javascript validation, so flow validation can take place.
To access vscode preference, ALT+F,P,S for windows, ⌘+, for mac.
then you have flowtype installed with visual result with every key stroke:

Hope this helps!
I recently wanted to reset a react-native project to most recent version, and so I initialised the seed project - "AwesomeProject"... The problem is that it comes with 19 flowtype errors "out of the box"

I am reluctant to make changes to these files as it may create knock on effects. Does anyone have a work around?
In general, whenever you want flow to ignore a file, you can just specify that file under the [ignore] section of your .flowconfig.
That said, I just react-native init'd a project, using react-native-cli 1.0.0 and react-native 0.29.1, and ran a flow server on the root of my project, and didn't get any errors.
My project was passing on Travis till my last commit. After this commit, Travis says:
Error: Cannot find module 'tv4' (at https://travis-ci.org/a85/Newman/builds/37216427#L141)
It has installed tv4#1.1.3 as part of the build (as seen at https://travis-ci.org/a85/Newman/builds/37216427#L40)
In version 1.1.3 of tv4, the name field in package.json is "tv4" (https://github.com/geraintluff/tv4/commit/4887d0f073951db681d23b9fde69ed7a9092fdea), so I guess it's not a case issue.
I've tried rebuilding a number of times, but it hasn't helped. Running grunt test locally works perfectly.
Any ideas?
I have the same issue, but i managed to fix this when i changed package.json to the following:
{"main": "tv4.js"}
Instead of
{"main": "tv4.min.js"}
