[英]Building wheel for psycopg2 ... error pip3 install psycopg2?
[英]ERROR: Failed building wheel for psycopg2
我一直在尝试将我的数据库连接到 pgadmin4。 我连接成功,但现在我的 heroku 应用程序返回内部服务器错误。 为了调试这个我做heroku logs -t
它返回ImportError: No module named psycopg2
。 所以我然后尝试做pip install psycopg2
但我收到以下错误:

It appears you are missing some prerequisite to build the package from source.
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.

我尝试做pip install psycopg2-binary
但我已经安装了它。 我也尝试了已经提出的问题,但没有任何效果。 提前致谢
psycopg2-binary
不是psycopg2
的依赖项。 它是一个替代品。
因此,如果psyocpg2
无法安装,只需安装psycopg2-binary
即可。
差异归结为编译。 psycopg2-binary
是预编译的二进制文件,而psycopg2
将专门为您的系统编译。 这是首选,但如果您没有安装适当的编译器,则安装将失败。 在这种情况下,您可以改用预编译的二进制psycopg2-binary
。 它是一个替代品(即您仍然使用import psycopg2
)。
