Getting errors on TravisCI

Hi,

I'm getting the following errors on my TravisCI but it doesn't happen on my local machine.
(Note this could be related to https://github.com/amilajack/eslint-plugin-flowtype-errors/issues/41)

Here is my eslint config:
```
{
"parser": "babel-eslint",
"extends": [
"airbnb",
"plugin:react/recommended",
"plugin:flowtype/recommended",
"prettier",
"prettier/react",
"prettier/flowtype"
],
"plugins": ["react", "prettier", "flowtype", "flowtype-errors"],
"rules": {
"jsx-a11y/anchor-is-valid": [
"error",
{
"components": ["Link"],
"specialLink": ["to"],
"aspects": ["noHref", "invalidHref", "preferButton"]
}
],
"prettier/prettier": [
"error",
{
"singleQuote": true,
"trailingComma": "es5",
"tabWidth": 2
}
],
"flowtype-errors/show-errors": 2,
"no-warning-comments": [
1,
{ "terms": ["todo", "fixme", "xxx"], "location": "start" }
],
"react/sort-comp": [0],
"react/no-unescaped-entities": [0],
"react/jsx-boolean-value": [0],
"react/jsx-filename-extension": [1, { "extensions": [".js", ".jsx"] }],
"react/default-props-match-prop-types": "off",
"jsx-a11y/no-static-element-interactions": [0]
},
"env": {
"es6": true,
"browser": true
}
}

```

And my flow config:
```
[ignore]
.*/build/.*
.*\.json

[include]

[libs]

[lints]

[options]

```

Any idea what could be wrong?

Thank you.
