Q&A
最初の５行に登場する「エラー」の内容が書かれていませんので追記されては。
あとインストールされたモジュールのソースをいじるのは何か違う気がします。
chokidarをインストールしましたが、エラーが出てしまい困っています。
create-react-appで作成した環境です。：
以下がやったことです。
・fseventsが無いというエラーでnpm i fseventsするとMACでないとインストールできないというエラー（centos7です。エラー内容を下に追記（追記２））
・サーバーを起動すると、/node_modules/chokidar/lib/fsevents-handler.jsの↓でエラーが出るのでコメントアウト。
try { fsevents = require('fsevents'); } catch (error) { if (process.env.CHOKIDAR_PRINT_FSEVENTS_REQUIRE_ERROR) console.error(error); }
次にまたサーバーを立ち上げるとサーバーは正常に立ち上がりますが、ブラウザに以下のエラーが出ます。
TypeError: The "original" argument must be of type Function promisify node_modules/util/util.js:605 602 | var kCustomPromisifiedSymbol = typeof Symbol !== 'undefined' ?

以上は下記URLを見る前にやったことですが、下記URLのように --save-optionalでインストールしても同じくlinuxだからインストールできないというエラーが出てしまいます。

よろしくお願いします。
追記１：
package.jsonに
"optionalDependencies": { "fsevents": "*" },
を書いたうえでnpm i fsevents npm i fsevents --save-optional しましたが同じエラーです。
追記２：fseventsインストール時にでるすべての出力
