// This script takes the current url and converts the path and query
// string into just a query string, and then redirects the browser
// to the new url with only a query string and hash fragment,
// e.g. https://www.foo.tld/one/two?a=b&c=d#qwe, becomes
// https://www.foo.tld/?/one/two&a=b~and~c=d#qwe
// Note: this 404.html file must be at least 512 bytes for it to work
// with Internet Explorer (it is currently > 512 bytes)
// If you're creating a Project Pages site and NOT using a custom domain,
// then set pathSegmentsToKeep to 1 (enterprise users may need to set it to > 1).
// This way the code will only replace the route part of the path, and not
// the real directory in which the app resides, for example:
// https://username.github.io/repo-name/one/two?a=b&c=d#qwe becomes
// https://username.github.io/repo-name/?/one/two&a=b~and~c=d#qwe
// Otherwise, leave pathSegmentsToKeep as 0.
var pathSegmentsToKeep = 0;
var l = window.location;
l.replace(
l.protocol + '//' + l.hostname + (l.port ? ':' + l.port : '') +
l.pathname.split('/').slice(0, 1 + pathSegmentsToKeep).join('/') + '/?/' +
l.pathname.slice(1).split('/').slice(pathSegmentsToKeep).join('/').replace(/&/g, '~and~') +
(l.search ? '&' + l.search.slice(1).replace(/&/g, '~and~') : '') +
l.hash
);

2. 新增以下 script 到 index.html 的 <head> 裡面
<script type="text/javascript">
// Single Page Apps for GitHub Pages
// MIT License
// https://github.com/rafgraph/spa-github-pages
// This script checks to see if a redirect is present in the query string,
// converts it back into the correct url and adds it to the
// browser's history using window.history.replaceState(...),
// which won't cause the browser to attempt to load the new url.
// When the single page app is loaded further down in this file,
// the correct url will be waiting in the browser's history for
// the single page app to route accordingly.
(function(l) {
if (l.search[1] === '/' ) {
var decoded = l.search.slice(1).split('&').map(function(s) {
return s.replace(/~and~/g, '&')
}).join('?');
window.history.replaceState(null, null,
l.pathname.slice(0, -1) + decoded + l.hash
);
}
}(window.location))
</script>
之後 yarn build 後 cd build && serve 即可測試，重新整理後不會找不到路徑了
