在Heroku上部署時帶有GDAL的Django拋出錯誤

當我使用 Heroku 部署我的 Django 應用程式時，GDAL 似乎存在一些問題。當我運行時，heroku logs --tail我得到以下資訊：

我正在使用postgis啟用的 PostgreSQL 資料庫（它是一個地理定位應用程式）。

我已經安裝了這個buildpack并且我的requirements.txt檔案GDAL==2.4.0在那里（與 buildpack 似乎要安裝的版本一致）。

我的理解dylibs是它們是 MACOS 檔案型別 - 因此Heroku指向我的本地機器GDAL而不是 a Heroku dyno，我對這一切都很陌生，但我相信我需要弄清楚為什么會發生這種情況以及如何改變 Heroku 的位置尋找GDAL.

uj5u.com熱心網友回復：

好的，我是如何解決這個問題的：

1. 確保你的 GDAL 沒有什么時髦的settings.py- 我已經按照這個答案讓 GDAL 在開發程序中在我的本地服務器上作業，并且不得不從我的路徑中洗掉它settings.py
2. pip uninstall GDAL
3. pip freeze > requirements. txt
4. 添加heroku-geo-buildpack（鏈接）并確保將其設定buildpack為您的應用的第一個
5. git commit 你所有的改變
6. 再次推送應用
