How to use pip to install module in Yocto recipe


I am updating my pyadi-iio installation recipe from 0.0.14 to 0.0.15. However the newer version no longer uses setup.py the new recommended way to install from source is pip install ..

Based on this question, I changed my recipe from:

LICENSE = "CLOSED"
 
SRC_URI[md5sum] = "d258374fab29540e9f9ee38d36257a2e"
SRC_URI[sha256sum] = "fb6a9a47ed4af5a5c50819cf9973a93ea7148c2b70d775edb71bdf0e7da292b6"
 
PYPI_PACKAGE = "pyadi-iio"
 
inherit pypi setuptools3
 
RDEPENDS:${PN} += " python3-numpy"

to

LICENSE = "CLOSED"
 
SRC_URI[md5sum] = "ea94069ddb468988fe5a6465ecdf3ac1"
SRC_URI[sha256sum] = "c3d04f027ea1d4660da825f2f2c2843f7a3d7876fa5e0c3f46725f70ccd08365"
 
PYPI_PACKAGE = "pyadi-iio"
 
inherit pypi
 
DEPENDS = "python3-pip-native"
 
RDEPENDS:${PN} += " python3-numpy"
 
do_install() {
    pip3 install .
}

However, I get an error saying pip can't access my .cashe/pip folder.

How do I install a python package without setuptools3 and using pip?


Solution

  • I got it to work by not using pip and instead using install and cp.

    LICENSE = "CLOSED"
     
    SRC_URI[md5sum] = "ea94069ddb468988fe5a6465ecdf3ac1"
    SRC_URI[sha256sum] = "c3d04f027ea1d4660da825f2f2c2843f7a3d7876fa5e0c3f46725f70ccd08365"
     
    PYPI_PACKAGE = "pyadi-iio"
     
    inherit pypi
     
    RDEPENDS:${PN} += " python3-numpy"
     
    FILES:${PN} += "${libdir}/python3.10/site-packages/adi ${libdir}/python3.10/site-packages/pyadi_iio.egg-info"
     
    DIRFILES = "1"
     
    do_install() {
        install -m 777 -d ${D}${libdir}/python3.10/site-packages/
        cp -r ${S}/pyadi_iio.egg-info ${D}${libdir}/python3.10/site-packages/pyadi_iio.egg-info
        cp -r ${S}/adi ${D}${libdir}/python3.10/site-packages/adi
    }
    

    I was getting a file conflict error when building the image, adding DIRFILES = "1" fixed the problem based on this answer.
