Pip Yocto core基座映像上的枕头安装错误

我试图在Yocto core base映像中安装Pillow，但当我使用pip3安装Pillow时，我收到以下错误消息：

Running setup.py install for Pillow ... error
    Complete output from command /usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/var/volatile/tmp/pip-install-n_gnb4rr/Pillow/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /var/volatile/tmp/pip-record-1mienill/install-record.txt --single-version-externally-managed --compile:

    During handling of the above exception, another exception occurred:

您不能在Yocto运行系统中使用pip，您必须为它创建一个配方。python枕头配方已经存在于中。谢谢@Nayfe，我在中手动安装了libjpg
