【问题描述】:
在安装 requirements.txt 文件之前,我一直在关注文档。尝试安装第 6 行“psycopg2==2.5.3”时总是失败。这是消息 -
Downloading/unpacking psycopg2==2.5.3 (from -r requirements.txt (line 6))
Downloading psycopg2-2.5.3.tar.gz (690kB): 690kB downloaded
Running setup.py (path:/Users/pimpc/Sites/python/herokudemo/python-getting-started/venv/build/psycopg2/setup.py) egg_info for package psycopg2

or specify the full executable path with the option:

or with the pg_config option in 'setup.cfg'.

当然,我找到了几篇关于此的帖子。所以我开始检查事情。我相信用于 mac 的 postgres 应用程序带有 psycopg2。我确实已将 postgres 添加到我的路径中,并在运行“echo $PATH”的终端中签入。我没有任何其他旧版本冲突。 postgres 文档说我应该像这样将它添加到我的路径中 -
export PATH="/Applications/Postgres.app/Contents/Versions/9.3/bin:$PATH:$PATH"
我已重新启动 postgres 应用程序,停用并重新启动虚拟环境,无论如何我都会收到相同的错误。
我可能会忽略什么!我已经阅读并阅读了此处的其他帖子,甚至包括有关此问题的博客。
【问题讨论】:
-
当您停用并重新激活虚拟环境时,您的 PATH 将被重置。因此,请在激活虚拟环境时编写导出语句。
