設備和模擬器上的流星 ios 空白屏幕

Question

我的 Meteor 應用程序在瀏覽器和 android 設備中運行良好，但是在 ios 設備和模擬器上，啟動后我總是卡在空白屏幕上。 Xcode 對我來說是新手，所以我不知道是不是我做錯了什么？ 但是，我按照 ios 測試說明進行了操作。 我還嘗試了許多修復，我的谷歌在我能想到的每個關鍵字搜索中都充斥着最后一次看到的日期。 我的 Safari 開發者控制台顯示這些輸出錯誤粘貼在下面.......有沒有其他人看到過這個問題或知道如何解決它？

（出於明顯的安全原因，將我的 IP 地址替換為http://000.000.00.000:3000/ 。另請注意：body 元素為空，但如果我在控制台中編輯 html，則會更新 iphone 屏幕。似乎我的主頁從未呈現過）

Answer 1

我遇到了同樣的錯誤，並通過以下方式解決了它：

1. 刪除node_modules文件夾
2. 執行meteor reset
3. 刪除.cache文件夾
4. 再次安裝依賴項（我使用了紗線）。
5. 完成了！！！ 該應用程序應在模擬器和設備中運行。

測試：

• Mac OS 11.1 大蘇爾
• 代碼 12.3
• 流星 1.12.1
• 前端是使用 akryum 包使用 Vue 和 Vuetify 構建的。
• iPhone 12 Pro Max 上的 iOS 14.3 模擬器
• iPhone SE 上裝有 iOS 14.3 的物理設備

我希望這也能幫助你。
