pyodbc安装在heroku服务器错误命令＆＃34; gcc＆＃34;退出状态1失败 - Django项目

Question

我正在运行一个heroku应用程序，并使用pyODBC。

当我尝试在我的heroku服务器上安装pyodbc时出现此错误。

当我尝试将pyodbc放在requirements.txt文件中时，会发生同样的事情。

我根本不知道如何处理此错误，我似乎无法通过windows heroku toolbelt找到如何在heroku服务器上使用sudo apt-get等命令。

这是错误过程。

我还试图通过pip和旧谷歌代码项目中的zip来安装一些旧的pyodbc版本： https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/pyodbc/pyodbc-3.0.7.zip

UPDATE ::您需要制作自己的heroku buildpack。见图。

Answer 1

您没有安装unixODBC dev软件包。我不确定如何在Heroku上安装，但这里有两个例子：

Ubuntu示例：

sudo apt-get install unixodbc unixodbc-dev

CentOS示例：

sudo yum install unixODBC-devel

您可能还想考虑安装virtualenv，而不是在系统范围内安装pyodbc。
