Question

当我运行'pip install psycopg2 == 2.7.3'时，它基本上会爆炸并显示错误代码1，并退出状态1120。我在Windows 10上，茫然无措，因为我什至无法解析此错误信息。任何帮助将不胜感激。

我相信PATH设置正确，我试图获取mod_wsgi，因为有人说它有助于退出代码1120，但实际上在尝试安装该代码时也会遇到相同的错误。

更多参考，我在Windows 10中运行，并以管理员身份运行命令提示符。

我遇到了同样的问题，只需安装适当版本的python（64位而不是32位）即可解决。

如果您的PC是64位的，请注意并下载WindowX86-64版本。另外，您还必须安装postgreSQL并在PATH变量中进行设置。例如C:\Program Files\PostgreSQL\12\bin是我在PC上看到的路径。
