ReactJS 隨機意外的令牌'<'

Question

項目是使用 create-react-app 創建的。 沒有彈出。 沒有 webpack 配置。 默認"react-scripts": "^3.4.0" 。 在dev版本上沒有錯誤。 但是在生產中，當用戶長時間停留在一個頁面上並單擊鏈接時，它會顯示白頁，並且在更新站點（部署新版本）之后。 這個錯誤是隨機出現的。 控制台輸出

意外標記“<”

並且沒有其他信息。

有我的package.json

不知道怎么樣但是在啟用sourcemap此錯誤不會顯示。 我從yarn build刪除了這個命令：

GENERATE_SOURCEMAP=false
