【问题描述】:
我尝试从this site 安装 psycopg2(PostgreSQL 数据库适配器),但是当我在 cd 进入包并写入后尝试安装时
python setup.py install
我收到以下错误:
Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
我也尝试过“sudo pip install psycopg2”,得到了同样的信息。
阅读docs后,它要求查看setup.cfg文件(如下):
[build_ext]
define=
# PSYCOPG_DISPLAY_SIZE enable display size calculation (a little slower)
# HAVE_PQFREEMEM should be defined on PostgreSQL >= 7.4
# PSYCOPG_DEBUG can be added to enable verbose debug information
# "pg_config" is required to locate PostgreSQL headers and libraries needed to
# build psycopg2. If pg_config is not in the path or is installed under a
# different name uncomment the following option and set it to the pg_config
# full path.
#pg_config=
# Set to 1 to use Python datetime objects for default date/time representation.
use_pydatetime=1
# If the build system does not find the mx.DateTime headers, try
# uncommenting the following line and setting its value to the right path.
#mx_include_dir=
# For Windows only:
# Set to 1 if the PostgreSQL library was built with OpenSSL.
# Required to link in OpenSSL libraries and dependencies.
have_ssl=0
# Statically link against the postgresql client library.
#static_libpq=1
# Add here eventual extra libraries required to link the module.
#libraries=
但是,我不确定是否要编辑此文件,因为文档说明如下:
then take a look at the setup.cfg file.
Some of the options available in setup.cfg are also available as command line arguments of the build_ext sub-command. For instance you can specify an alternate pg_config version using:
$ python setup.py build_ext --pg-config /path/to/pg_config build
Use python setup.py build_ext --help to get a list of the options supported.
我已经获得了支持的选项列表,但我不确定从那里去哪里
