I created a VueJS app and I'm getting the following error when I look at the source code in the web browser:
<noscript>
<strong>We're sorry but pay-loader doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
</noscript>
I tried a creating a vue.config.js file in the root directory as suggested here :
webpack config missing in vuejs
This didn't work for me, how can fix this issue?
I'm using vue version 3.0.0-rc.5
Thanks
Vue Devtools works on all demos/examples online but not on my local pages. Even with the following, the Vue Devtools icon remains gray ("Vue.js not detected"). Why?
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
</head>
<body>
<div id="app"></div>
<script>
Vue.config.devtools = true;
</script>
</body>
</html>
The Vue source you are using there looks to be minimized / production build to me. You need to use the non minimized / non-production build. Try https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.15/vue.js instead.
Also if you are working with local files i.e. accessing a page like file://... then "you need to check "Allow access to file URLs" for this extension in Chrome's extension management panel." see https://github.com/vuejs/vue-devtools
You must add at-least 1 instance of vue, for the devtools to detect it. So, do:
new Vue({el: '#app'})
You can try to refresh the browser first.
If didn't work, make sure that if you're compiling CSS and JavaScript to have have development compilation for both not a compilation for production with minified files
If at least one file is minified for prod, devtools will not show up
I have the following code with a simple working Vue.js application. But the vue.js devtools is not responding. It was working well a few days ago, now it's not working anymore what could possibly be going wrong? when I go to https://chrome.google.com/webstore/detail/vuejs-devtools/nhdogjmejiglipccpnnnanhbledajbpd, it says it is already added.

One alternative is to set up a local web server, as the OP already stated.
The other - which IMHO is faster and less harassing - is letting the extension have access to file URLs, which is disabled by default.
Simply go to chrome://extensions and leave the "Allow access to file URLs" box checked for Vue.js devtools.
Sources:
https://github.com/vuejs/vue-devtools#common-problems-and-how-to-fix
I tried all of the ways presented in answers here, but none of them worked for me (neither for chrome nor for firefox).
Finally I found an answer: If you still have this problem, you can try to uninstall the current version of Vue extension and install beta version: https://v3-migration.vuejs.org/breaking-changes/introduction.html#devtools-extension
Remember to restart your browser afterwards.
UPDATE: 2021 May 30,
If you are using Vue 3, old dev tools versions won't work, so just use the new beta version.
https://chrome.google.com/webstore/detail/vuejs-devtools/ljjemllljcmogpfapbkkighbhhppjdbg
To solve this, simply go to chrome://extensions/, scroll down to the Vue.js devtools and enable the "Allow Access to file URLs" by clicking on its checkbox.
Source: https://github.com/vuejs/vue-devtools/issues/236
Had the same issue and solved it by adding
Vue.config.devtools = true;
after Vue.js import script, then take look at chrome devtools. You will see a tab called Vue to inspect your vue instance.
reference: https://v2.vuejs.org/v2/api/#devtools
I found out the answer, I was viewing a plain html file on my computer which was making the vue.js tool not load. I loaded up my local xampp server and ran the application from the local machine server url again and now vue.js devtools is working! :)
Also you can disable with Vue config:
https://v2.vuejs.org/v2/api/#devtools
in the extensions folder in chrome browser, under the details tab in vue devtools extension, check the box having allow access to file URLs,
this worked for me..
If you're using Vue 3 and experiencing this issue, try installing the beta version of the Vue Devtools. It may help until the stable version gets the major refactor.
I had the same issue & solved it by:
Installing this extension Vue Dev Tools Beta Chrome Extention
Reloading the chrome browser.
i had this problem, and i was expecting the vue-devtools to work by just including it. i had it console log the version
console.log("Vue Version " +Vue.version );
but this didnt work to actually load an instance of vue.
took me a few minutes, but once i actually created a vue instance, then it worked. this was the hello world example that made the devtools work :)
let data = {
message: 'Hello World'
}
new Vue({
el: '#application',
data: data
})
I solved the same problem.
But in my case Vue.js Chrome Devtools didn't detect Vue.js because in html file was <script src="https://unpkg.com/vue"/>
I replaced it to <script src="https://unpkg.com/vue"></script>
Now Chrome Devtools is detecting Vue.js perfectly.
Thanks for exapmle above.I use vue#2.4.4 and open my html by file://
In the case of Firefox, install the beta version of vue-devtools, which supports Vue 3.
If you have already turned on Allow Access to file URLs in chrome://extensions/ -> Vue Devtools and it still does not work, try reinstall the Vue Devtools, might work for you.
check if vuejs app is not embedded in an iframe such as in a storybook app.
the hack in such a case is to work outside the parent frame working directly on the url of your iframe and the vue devtools should work fine.
I'm using Vue in electron and I have the electron main "app" separated Vue's "app".
When in the the debugger console, typing Vue was giving the error Uncaught ReferenceError: Vue is not defined
Here was my fix
window.vue = new Vue({
components: {
App,
Login,
},
router,
store,
template: '<App/>',
}).$mount('#app');
The work-around was assigning window.Vue so the devtool could find it.
The same problem here, and I've solved it.
If you are developing in the localhost environment and using Chrome Dev Tools then you need to give permission for the Vue.js extension to access the local files on your computer.
Config your Vue.js tool in Chrome extensions
Search for "Vue.js devtools"
Click on details
Check the "Allow access to file URLs" checkbox
In my case I just had compiled for production npm run prod - which was the issue. As I ran in dev npm run dev, it started recognizing Vue.
I'm hoping someone with some experience in Breeze/Durandal 2 on .NET 4.0 will be able to assist me with this error, as I'm pretty new to the mix.
I've been working on a Durandal 2/KO/Require SPA project that lately has been compiling fine and running on my IIS7. I need this app to be compatible with IE8, so I imported the shim and sham js libs as such:
<!-- ECMAScript 5 compatibility shims for IE8 -->
<!--[if lt IE 9]>
<script src="lib/ie8/html5shiv.min.js"></script>
<script src="lib/ie8/respond.js"></script>
<script src="lib/ie8/es5-shim.min.js"></script>
<script src="lib/ie8/es5-sham.min.js"></script>
<![endif]-->
<script src="lib/jquery/jquery-1.9.1.min.js"></script>
<script src="lib/knockout/knockout-3.1.0.js"></script>
<script src="/Scripts/q.min.js"></script>
<script src="/Scripts/breeze.debug.js"></script>
<script src="lib/bootstrap/js/bootstrap.js"></script>
I also need to be able to access data from a DB so I tried adding BreezeJS to the mix. According to Breeze's documentation, in order for this to work I had to remake the project in VS as ASP.NET MVC4 Project using the Empty Template. After that I imported the Breeze files using NuGet:
Install-Package Breeze.WebApi
Then I added in my pre-existing views, controllers, libraries, css, etc. to the newly created project. Now when I compile using IE8 I get the following error. This error does not show up for Firefox or Chrome:
Unhandled exception at line 125, column 13 in
http://localhost:64185/lib/durandal/js/composition.js
(Edited for readability)

I thought this might be a compatibility issue with JQuery so I attempted different versions there. I've made sure that my DocType is set to:
<!DOCTYPE html>
and that I have the following meta tag:
<meta http-equiv="X-UA-Compatible" content="IE=edge, chrome=1" />
However I doubt either of those would cause issues with IE8 and Durandal. Has anyone else experienced a similar issue to mine? Am I experiencing this error because I haven't configured something on the MVC4 side?
Any advice would be greatly appreciated.
Thank you
After further digging into the Durandal composition.js I found that the skipActivation parameter in the "tryActivate" function was undefined, which resulted in the error. I'm pretty sure this problem is a result of IE8 support from Durandal, so I went ahead and scrapped IE8 and I am now developing for IE9 and up.
This isn't a fix, but I've had enough headaches with this and I will be moving on ...
I have a problem. I had a app on the manifest v1.
But now it tells me to change it to v2. But it gives me an error like:
Refused to execute inline script because it violates the following
Content Security Policy directive: "script-src 'self'
chrome-extension-resource:".
I tried to change in the manifest:
"web_accessible_resources": [
"jquery-1.7.1.min.js",
"plugin.js"
]
But in the html code, I have:
<script type="text/javascript" src="jquery-1.7.1.min.js"></script>
<script src="plugin.js"></script>
How do I put it now? Should I delete that? If i delete it won't run! My popup doesn't even opens anymore :|
Hope you understood my problem, thanks
(I'll thank more if someone gave an example of API v2 using javaScript to download :) )
This error usually means that there is some script being executed directly inside your HTML page, not included via an external javascript file.
For example:
<script type="text/javascript">alert('hello');</script> embedded inside your html file is an inline script. The correct way to do it would be
<script type="text/javascript" src="hello.js"></script> .
Your file hello.js would include alert('hello');
I hope this helps.
