Just a suggestion - from what can be seen in the issue tracker, a docker container per release might be a really good idea. Simple install and build would help a lot - users won't have doubts on how to install/use vuepress, and all "works on my machine" issues will go away. FYI @heyheni

Try 1.0.0-alpha.20.

[jrappen]

this was fixed in vuejs/vuepress@256b7c4

[jrappen]

related to #949 and #908

@ulivz

Try 1.0.0-alpha.20.

Needless to highlight that Docker container suggested by @heyheni in #974 makes sense. No one would have to "try", we would have CI to "try" for us and make sure it's (1) buildable and (2) workable at least to the level of the initial installation instructions. Besides, solves #949, #908 and this #985 before they even arise.
