我試圖在CentOS 6.5上安裝PostgreSQL extension Multicorn。但我所遇到的問題是，CentOS上的默認python版本是2.6，而Multicorn需要2.7或3.3。我試圖用this tutorial編譯Multicorn，但它是一個有點過時，並在那裏Python版本變更步驟不工作了：如何更改生成文件中的python版本 - 編譯Multicorn（PostgreSQL FDW擴展）
sed -i 's/^PYEXEC = python$/PYEXEC = python2.7/' Makefile
有人可以幫助我再次作出上述命令的工作，或顯示我如何編輯makefile來改變python的版本？我可以在命令行中用python2.7調用python 2.7版。版本2.6只用python調用 - 顯然，如果不打破CentOS，我無法改變這一點。
這是生成文件：
MODULE_big = multicorn
OBJS = src/errors.o src/python.o src/query.o src/multicorn.o
DATA = $(filter-out $(wildcard sql/*--*.sql),$(wildcard sql/*.sql))
DOCS = $(wildcard doc/*.md)
EXTENSION = multicorn
EXTVERSION = $(shell grep default_version $(EXTENSION).control | sed -e "s/default_version[[:space:]]*=[[:space:]]*'\([^']*\)'/\1/")
all: preflight-check sql/$(EXTENSION)--$(EXTVERSION).sql
install: python_code
sql/$(EXTENSION)--$(EXTVERSION).sql: sql/$(EXTENSION).sql
cp $< [email protected]
preflight-check:
./preflight-check.sh
python_code: setup.py
cp ./setup.py ./setup--$(EXTVERSION).py
sed -i -e "s/__VERSION__/$(EXTVERSION)-dev/g" ./setup--$(EXTVERSION).py
