Installing mern-cli with Yarn results in mern-init(1) does not exist, try --help #21
Open
Description
When installing mern-cli via Yarn, the package successfully installs
yet am unable to run any of the CLI commands.
The same issue has been found with the vue-cli package and documented in the following issues:
vuejs/vue-cli#193 and vuejs/vue-cli#205
The issue was resolved in the following respective PR: vuejs/vue-cli#206
I am accompanying this issue with a proposed PR (#22) that resolves the issue similarly to the the vue-cli solution and would like your feedback on whether this would be an appropriate solution for mern-cli.
Below is a comparison of installing the package via Yarn and NPM followed by my environment details.
