无法在mac osx 10.9上安装psycopg2 2.5+

Question

Here is the error log:

building 'psycopg2._psycopg' extension

creating build/temp.macosx-10.9-intel-2.7

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

error: command 'cc' failed with exit status 1

Any suggestions? any workaround? I am entirely blocked by this for about a day.

Answer 1

This one works for me:

export CFLAGS=-Qunused-arguments export CPPFLAGS=-Qunused-arguments

clang error: unknown argument: '-mno-fused-madd' (python package installation failure)

Answer 2

Try:

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install psycopg2

Answer 3

Im pretty sure pyscopg2 doesnt support 9.3 yet. Here's the documentation http://initd.org/psycopg/docs/news.html

I see references for 9.1 and 9.2 but nothing for 9.3 especially since it was just released a few months ago. 9.3 incorporates it's own Foreign Writable wrapper which other modules like Multicorn now utilize.

I could be wrong, just a possibility. Try using 9.2 and see if it works.
