node.js - Error installing node-postgres on Amazon Linux. Missing pg_config.h file -

-

this error seems common on windows boxes, amazon linux ec2 instance throwing error when npm install pg:

../src/binding.cc:1:23: fatal error: pg_config.h: no such file or directory  #include <pg_config.h>                        ^ compilation terminated. make: *** [release/obj.target/binding/src/binding.o] error 1 make: leaving directory `/home/ec2-user/macros/test/statehash/node_modules/pg/build' gyp err! build error  gyp err! stack error: `make` failed exit code: 2 gyp err! stack     @ childprocess.onexit (/usr/lib/node_modules/node-gyp/lib/build.js:267:23) gyp err! stack     @ childprocess.eventemitter.emit (events.js:98:17) gyp err! stack     @ process.childprocess._handle.onexit (child_process.js:807:12) gyp err! system linux 3.4.82-69.112.amzn1.x86_64 gyp err! command "node" "/usr/lib/node_modules/npm/node_modules/node-gyp/bin/node-gyp.js" "rebuild" gyp err! cwd /home/ec2-user/macros/test/statehash/node_modules/pg gyp err! node -v v0.10.28 gyp err! node-gyp -v v0.10.6 gyp err! not ok

i'm on amazon linux 2014.03, , it's micro instance running node 0.10.28.

postgres 9.2.7 installed amazon repos. specifically, postgresql9* packages.

on fresh updatedb, locate pg_config returns

/usr/bin/pg_config /usr/share/locale/cs/lc_messages/pg_config-9.2.mo /usr/share/locale/de/lc_messages/pg_config-9.2.mo /usr/share/locale/es/lc_messages/pg_config-9.2.mo /usr/share/locale/fr/lc_messages/pg_config-9.2.mo /usr/share/locale/it/lc_messages/pg_config-9.2.mo /usr/share/locale/ja/lc_messages/pg_config-9.2.mo /usr/share/locale/ko/lc_messages/pg_config-9.2.mo /usr/share/locale/nb/lc_messages/pg_config-9.2.mo /usr/share/locale/pl/lc_messages/pg_config-9.2.mo /usr/share/locale/pt_br/lc_messages/pg_config-9.2.mo /usr/share/locale/ro/lc_messages/pg_config-9.2.mo /usr/share/locale/ru/lc_messages/pg_config-9.2.mo /usr/share/locale/sv/lc_messages/pg_config-9.2.mo /usr/share/locale/ta/lc_messages/pg_config-9.2.mo /usr/share/locale/tr/lc_messages/pg_config-9.2.mo /usr/share/locale/zh_cn/lc_messages/pg_config-9.2.mo /usr/share/locale/zh_tw/lc_messages/pg_config-9.2.mo /usr/share/man/man1/pg_config.1.gz

but locate pg_config.h returns nothing.

any ideas?

the postgresql9, postgresql9-libs, , postgresql9-server installed default, not postgresql9-devel.

the header files required node-postgres in missing development package. following steps fixed problem:

  1. remove node-postgres directory:

    $ rm -rf node_modules/pg

  2. install postgres development package repos (match version - amazon repos mess when comes postgres):

    $ sudo yum install postgresql9-devel

  3. reinstall node-postgres (i'm doing locally, might using -g option):

    $ npm install pg

the pg_config.h file should there, installation should work fine!

php - Changing the visibility scope of parent methods in child classes -

-
i've got validator class , uservalidator class extends it. my validator has public method setrule(...) public visibility. when extend want change visibility of setrule(...) parent method private/protected within child it's visible child , no outsiders can call method from child. is possible? if so, how achieve it? from architectural point of view not recommended. stated in comments clean way set method protected children can access it. i cannot think of single use case put me in need call public method on parent class not allowed call on child class. that's against open/closed principle. classes should open extension, not modification. since not question i'll provide way how can achieved though. note: this method makes use of class responsible instantiation it's hack. solution not make use of php's native language features when throwing accessibility errors. first let's define classes had <?php class validator { ...
