那些遇到过的问题

客户端无法建立连接，macOS，django，odbc 17，pyodbc

sga*_*ich 5 python django odbc openssl path

一切正常，直到我重新启动笔记本电脑。

我有这个设置：

  • 蟒蛇3.8.9
  • Django 3.1.1
  • pyodbc 4.0.30
  • pyodbc.drivers()显示这个：['ODBC Driver 17 for SQL Server']

  • isql -v -k "DRIVER=ODBC Driver 17 for SQL Server;SERVER=<my server>,<my port>;UID=<my username>;PWD=<my password>"连接到数据库没有问题
  • 服务器名、端口、用户和密码似乎也是正确的，因为 jdbc 驱动程序可以正常工作，没有任何问题。
  • cat /etc/odbcinst.ini和cat /etc/odbc.ini- 都返回这个：

我按照Microsoft 官方说明重新安装了 ODBC 驱动程序。但这没有帮助。我仍然无法启动 django 服务器并面临以下错误：

我设法找到的所有答案都没有帮助，包括这个答案：升级 OpenSSL 后 ODBC 无法找到正确的 OpenSSL 版本

这很奇怪，一切都工作了很长一段时间，直到我重新启动我的笔记本电脑（没有操作系统更新，只是重新启动）。这个问题可能与导出一些带路径的变量有关吗？请帮我解决这个问题。

我不确定你是否能找到这个。但以下解决方案对我有用。我的 odbc 无法找到 ssl 版本 1。我这样做了：在我的 /usr/local/opt/ 中

rm openssl
Run Code Online (Sandbox Code Playgroud)

或者

rm openssl@3
Run Code Online (Sandbox Code Playgroud)

这个想法是删除它指向的任何 openssl 的链接。您也可以与您的发现者核实。

然后新建一个指向openssl1.1的链接

ln -s /usr/local/Cellar/openssl@1.1/1.1.1l_1 /usr/local/opt/openssl

  • 拉贾特谢谢你的回答。在我在这里发布这个问题之前我已经这样做了，但这对我没有帮助。但对我有帮助的是：我将文件夹“openssl@1.1”内的所有文件复制到“openssl”文件夹中。 (2认同)
