Hopefully it will fix this warning on installation:

npm WARN acorn-jsx@5.0.1 requires a peer of acorn@^6.0.0 but none is installed. You must install peer dependencies yourself.

$ npm ls acorn-jsx
[redacted]
└─┬ eslint@5.9.0
  └─┬ espree@4.1.0
    └── acorn-jsx@5.0.1

$ npm ls acorn

      └── acorn@5.7.3  deduped

@jaydenseric It won't, as this is an npm bug (see this comment for more information).
