Same here, after yesterday commits:

 WAIT  Extracting site metadata...

 TIP  Temp directory: /vuepress/packages/@vuepress/core/.temp

 TIP  Apply theme located at /dev/.vuepress/theme...
[vuepress] cannot resolve plugin "/dev/.vuepress/theme"
TypeError: Cannot read property 'startsWith' of undefined
    at PluginAPI.applyPlugin (/vuepress/packages/@vuepress/core/lib/plugin-api/index.js:213:41)
..

[zvinless]

This is happening for me whenever I define plugins as an array in my theme's index.js file,

e.g.:

module.exports = {
    plugins: [
        '@vuepress/blog'
    ]
}

fails (as does using require),
but object style, e.g.:

module.exports = {
    plugins: {
        '@vuepress/blog': { }
    }
}

works fine

I'm not sure how to define local, non-package plugins like this, though.

Also, in case things are open for feedback: having various distinct ways of defining plugins on top of shorthands feels kind of contradictory to being minimalistic. It'd be nice to just have one way of doing it so it's clear and easy to remember.

e8a35be fixed this for me!

Could you try the latest alpha version: 1.0.0-alpha.16?

@ulivz Problems persist.

Thanks @ulivz ! alpha.16 fixed it!
Have to agree with @zvinless , flexibility is nice, but it can be confusing and costly to maintain and document.

@ulivz Problems persist on Windows as well.

[ulivz]

@jrappen I guess this issue was duplicate of #908 (You are using the globally installed VuePress ), You can try the 1.0.0-alpha.17.

[jrappen]

@ulivz Exact same issue respectively on both macOS and Win10 with 1.0.0-alpha.17 as with 1.0.0-alpha.16.

[jrappen]

fixed in 256b7c4 which is part of alpha.20
