python脚本运行提示ModuleNotFoundError: No module named 'packaging'

如果你的目标环境中的python是通过交叉编译自行生成的，在脚本运行时可能会遇到这个提示

在你已经完成python的交叉编译后，你就需要crossenv，然后完成对应库的适配

 

#Make crossenv

pip install crossenv

python3 -m crossenv --without-pip $crosspy/bin/python3 /your/cross-env

 

#Activate into cross env

cd /your/cross-env/cross/bin

source activate

 

# install pip

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

python get-pip.py

 

# install dep libs，eg

pip install packaging numpy lark-parser netifaces

 

# copy dep-libs to $MODEL_INSTALL_PREFIX

cp -a /your/cross-env/cross/lib/python3.8/site-packages/packaging* $MODEL_INSTALL_PREFIX/lib/python3.8/site-packages/

......

 

find . -name "*old*" -exec bash -c 'mv "$1" "${1/old/old_new}"' _ {} \;
