python - SSL error installing pycurl after SSL is set -


just information start:

  • i'm running mac os 10.7.5
  • i have curl 7.21.4 installed (came dev tools believe)
  • i have python 2.7.1

i've been trying pycurl installed, every time try run it, get:

importerror: pycurl: libcurl link-time ssl backend (openssl) different compile-time ssl backend (none/other)

i first installed pycurl using setup:

python setup.py install

which didn't work (since ssl wasn't configured).

i have since uninstalled pycurl (sudo rm -rf /library/python/2.7/site-packages/pycurl*) before attempting:

export pycurl_ssl_library=openssl easy-install pycurl

and again before trying:

python setup.py --with-ssl install

however, i'm still getting same error ssl not compiled in. it's if instructions ignoring attempts.

setup.py doesn't complain @ when installing, easy install prints message after set pycurl_ssl_library env var:

src/pycurl.c:151:4: warning: #warning "libcurl compiled ssl support, configure not determine " "library used; no ssl crypto locking callbacks set, may " "cause random crashes on ssl requests"

which seems indicate it's ignoring fact told install openssl...

is there i'm missing in setup?

when get:
    failed: importerror: pycurl: libcurl link-time ssl backend (nss) different compile-time ssl backend (none/other)

you need recompile pycurl pycurl_ssl_library set. reinstall seems 2 stage process.

it seems pip downloads stuff somewhere, compiles , puts python can use it. if have compiled version in cache literally screwed because not recompile. "gives" python same thing, regardless of in pycurl_ssl_library variable.

the solution quite simple, erase cache force recompile. depending on operating system, cache might located in several places. go , search using fact there setup.py. has package = "pycurl" string in it. there no need trouble. latest pip version supports install --compile option.

upgrade latest pip:
    pip install --upgrade pip #healthy anyway

remove current pycurl with:
    pip uninstall pycurl

set pycurl_ssl_library need:
    export pycurl_ssl_library=nss #for me required setting

finally run
    pip install --compile pycurl

note might need -devel packages various header files needed in compilation process.

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

first of all, thank being patient know simple question more couple of weeks' experience figure out. i've seen folks persevere , helpful on here , hope you're willing me. here fiddle: http://jsfiddle.net/65uzf/ here 1 of places searched answers on here: ( vertically center image thumbnails fix-sized div ) tried solutions on there , didn't work out me. i've searched ~4 or 5 others, , been unsuccessful those, too. what want take large image (what linked background-image #ysypic , #tabpic divs) , display thumbnail version of image in confines of divs have set it. is, using background properties have laid out in css, portion of image displays inside of circular divs. without these properties, display defaults smaller section of image [presumably pi*(50^2) area in top left] terrible resolution. i not care if entire image doesn't display inside of circles (it won't, given difference in shape), , overflow not being displayed fine. want able see figu

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
