Fails to work with Vue < 2.1.5

Describe the issue / bug.

#

When using a Vue version in /app lower than 2.1.5, running dev results in:

[Vue warn]: Error when rendering component at D:\David\Documents\my-project2\app\src\components\LandingPageView.vue:

Uncaught TypeError: _vm._v is not a function

How can I reproduce this problem?

#

Use vue-cli to init a fresh new project, with Vue 2 and all optional packages enabled except for Vue-Resource (didn't try with a different setup). Disable eslint and testing setup. Next, before using npm install, change the package.json in /app to specify "2.1.4" for Vue instead of "^2.0.1". Then npm install and npm run dev.

If visual, provide a screenshot.

Tell me about your development environment.

• Node version: 6.9.4 (also used 6.9.1)
• NPM version: 4.1.1 (also used 3.x)
• vue-cli version: 2.7.0
• Operating System: Windows 10 x64

Right now I'm in a bit of a pickle because vue-icons is currently only working with Vue <= 2.1.4 until it's updated and I need a similar version of Vue for Keen-UI (although this will likely be updated within a few days). I had everything working with an older version of Vue (something like 2.0.3) but accidentally updated both package.jsons and when I tried to reverse the process, I came across this problem.

Sorry for the late reply, but this sounds like this might be an issue with keen-ui/vue-icons as it could be related to a recent VueJS release.

It is recommended to re-compile the dist file using the latest versions of vue-template-compiler and vue-template-es2015-compiler. The new generated code is backwards-compatible, but code generated by older versions of the compilers may not work properly with the latest runtime.

But I am getting this error with the default electron-vue project without having added any other packages.

Edit: I've tried fixing ALL versions in the package.jsons to their lowest values and still got the error. This is the part I don't understand.

Okay after experimenting, this is how I got it to work. This essentially reverts developer dependency versions before the breaking changes.

In app directory, npm install --save [email protected]
In root directory npm install --save-dev vue-loader@^10.0.0 [email protected].

That fixed everything, thanks! I thought it had something to do with vue-loader but I lacked fu to get it going myself.
