yocto d.getVar 실패

Question

요코 학습에서 http://book.yoctoprojectbook.com/index. 4 장은 다음 코드를 가지고 있습니다

SUMMARY = "Recipe to build the 'nano' editor" 

PN = "nano" 
PV = "2.2.6" 

SITE = "http://www.nano-editor.org/dist" 
PV_MAJOR = "${@bb.data.getVar('PV', d, 1).split('.')[0]}" 
PV_MINOR = "${@bb.data.getVar('PV', d, 1).split('.')[1]}" 

SRC_URI = "${SITE}/v${PV_MAJOR}.${PV_MINOR}/${PN}-${PV}.tar.gz" 
SRC_URI[md5sum] = "03233ae480689a008eb98feb1b599807" 
SRC_URI[sha256sum] = \ 
"be68e133b5e81df41873d32c517b3e5950770c00fc5f4dd23810cd635abce67a" 

python do_fetch() { 
    bb.plain("Downloading source tarball from ${SRC_URI} ...") 
    src_uri = (d.getVar('SRC_URI', True) or "").split() 
    if 0 == len(src_uri): 
     bb.fatal('Empty URI') 
    try: 
     fetcher = bb.fetch2.Fetch(src_uri, d) 
     fetcher.download() 
    except bb.fetch2.BBFetchException: 
     bb.fatal('Could not fetch source tarball.') 
    bb.plain("Download successful.") 
} 

addtask fetch before do_build 

python do_unpack() { 
    bb.plain("Unpacking source tarball ...") 
    os.system("tar x -C ${WORKDIR} -f ${DL_DIR}/${P}.tar.gz") 
    bb.plain("Unpacked source tarball.") 
} 

addtask unpack before do_build after do_fetch 

python do_configure() { 
    bb.plain("Configuring source package ...") 
    os.system("cd ${WORKDIR}/${P} && ./configure") 
    bb.plain("Configured source package.") 
} 

addtask configure before do_build after do_unpack 

python do_compile() { 
    bb.plain("Compiling package ...") 
    os.system("cd ${WORKDIR}/${P} && make") 
    bb.plain("Compiled package.") 
} 

addtask compile before do_build after do_configure 

do_clean[nostamp] = "1" 
do_clean() { 
    rm -rf ${WORKDIR}/${P} 
    rm -f ${TMPDIR}/stamps/* 
} 

addtask clean 

레시피는 meta-hello/recipes-editor/nano에 있습니다. 기본적으로 nano 텍스트 편집기 패키지를 작성하려고합니다. do_fetch() 작업에서 실패합니다. 일부 print 문 디버깅 후이 줄에서 오류가 발생했다고 알았습니다 : src_uri = (d.getVar('SRC_URI', True) or "").split(), 구체적으로는 d.getVar('SRC_URI', True)입니다. 정확히 무엇이 문제의 원인인지는 잘 모르겠습니다. 아무도 도와 주겠니? 나는 rocko 빌드 yocto을 실행 중입니다. 여기

내가 조리법 실행할 때 내가 얻을 터미널 출력 :

하지만, 나는이 예제를하려고하면 그것은 구문 분석하는 동안 실패 다음 bb.data.getVar ('PV', d는, 1) d.getV 할 필요가 있기 때문이다

ar ('PV', True). 이 조리법은 록코에서 분석 할 수 없으므로 내가 생각하는 조리법을 실행하고 있다고 생각하지 않습니다.
