在 heroku 上使用 pymssql 部署 Python Bottle 应用程序

Question

我在使用 pymssql 将我的网站部署到 heroku 时遇到问题。我正在使用以下构建包，但仍然有错误：

heroku config:add BUILDPACK_URL=https://github.com/amanjain/heroku-buildpack-python-freetds-pymssql.git

这是我不断收到的错误：

还有其他人遇到过这个问题吗？

该 buildpack 似乎是为 Linux 系统构建的，而且您似乎正在尝试在 Windows 上安装它。

在跟踪日志中，它似乎在 win32 目录中寻找 FreeTDS 构建：

warning: no files found matching 'win32/freetds.zip'

它似乎也安装了 Python 2.7。如果您刚刚开始，我强烈建议您使用 Python 3。祝您好运。
