我一直在关注文档,直到我安装了 requirements.txt 文件。尝试安装第 6 行“psycopg2==2.5.3”时总是失败。这是消息——

当然,我找到了几个关于这个的帖子。所以我开始检查东西。我相信适用于 mac 的 postgres 应用程序带有 psycopg2。我确实将 postgres 添加到我的路径中,并在运行“echo $PATH”的终端中签入。我没有任何其他旧版本冲突。postgres 文档说我应该像这样将它添加到我的路径中 -
导出路径="/Applications/Postgres.app/Contents/Versions/9.3/bin:$PATH:$PATH"
我已经重新启动了 postgres 应用程序,停用并重新启动了虚拟环境,无论如何我都会遇到同样的错误。
我可能会忽略什么!我已经阅读并阅读了此处的其他帖子,甚至是涵盖此问题的博客。
