Espressif plays with the compilation environment

Espressif Of ESP-IDF Recently released release/v5.0, I've been release/v4.3 On the development , Unconsciously, it has fallen behind 2 A version （ There's another one in the middle release/4.4 edition ）. Then put your own ESP-IDF Updated to release/v5.0 edition , Originally thought that the implementation ./install.sh The script is executed after . ./export.sh You can complete the setup of the compilation environment , Facts have proved that nothing can be plain sailing .

The operating system I use is uBuntu, The system information is as follows ：

No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.5 LTS
Release:	18.04
Codename:	bionic

Below is a list of some that are being installed ESP-IDF Of release/v5.0 Problems encountered in the compilation environment of and solutions .

1. python Version is too low

   stay ESP-IDF Of release/v4.3 On Development , I'm using python The version is 3.6.9. take ESP-IDF Upgrade to release/v5.0 After the ./install.sh Prompt python Version is too low , By looking at ./install.sh The script knows ,python Version check script ${IDF_PATH}/tools/python_version_checker.py, Continue to analyze the script, and now release/v5.0 Supported by pyhon The minimum version is 3.7 above .

   The solution is simple , upgrade python Version can , Can use update-alternatives Implement multiple python Version Management . This is what I installed python Of 3.8.12 edition .

   #!/usr/bin/env bash
   
   set -e
   set -u
   
   basedir=$(dirname "$0")
   IDF_PATH=$(cd "${basedir}"; pwd -P)
   export IDF_PATH
   
   echo "Detecting the Python interpreter"
   . "${IDF_PATH}/tools/detect_python.sh"
   
   echo "Checking Python compatibility"
   "${ESP_PYTHON}" "${IDF_PATH}/tools/python_version_checker.py"
   
   TARGETS=`"${ESP_PYTHON}" "${IDF_PATH}/tools/install_util.py" extract targets "[email protected]"`
   
   echo "Installing ESP-IDF tools"
   "${ESP_PYTHON}" "${IDF_PATH}/tools/idf_tools.py" install --targets=${
         TARGETS}
   
   FEATURES=`"${ESP_PYTHON}" "${IDF_PATH}/tools/install_util.py" extract features "[email protected]"`
   
   echo "Installing Python environment and packages"
   "${ESP_PYTHON}" "${IDF_PATH}/tools/idf_tools.py" install-python-env --features=${
         FEATURES}
   
   echo "All done! You can now run:"
   echo ""
   echo " . ${basedir}/export.sh"
   echo ""
   

   import sys 
   
   try:
       # Python 2 is not supported anymore but still the old way of typing is used here in order to give a nice Python
       # version failure and not a typing exception.
       from typing import Iterable
   except ImportError:
       pass
   
   OLDEST_PYTHON_SUPPORTED = (3, 7)  # keep it as tuple for comparison with sys.version_info
   
   
   def _ver_to_str(it):  # type: (Iterable) -> str
       return '.'.join(str(x) for x in it) 
   
   
   def is_supported():  # type: () -> bool
       return sys.version_info[:2] >= OLDEST_PYTHON_SUPPORTED[:2]
   
   
   def check():  # type: () -> None
       if not is_supported():
           raise RuntimeError(
               'ESP-IDF supports Python {} or newer but you are using Python {}. Please upgrade your '
               'installation as described in the documentation.'.format(
                   _ver_to_str(OLDEST_PYTHON_SUPPORTED), _ver_to_str(sys.version_info[:3])
               )
           )
   
   
   if __name__ == '__main__':
       check()
   

2. /home/esp/.espressif/python_env/idf5.0_py3.8_env/bin/python: No module named pip

   This problem is very strange , At first I thought I python Of 3.8.12 Version is not installed pip, So you can install it directly through the following commands pip:

   sudo apt install python3-pip
   

   After the installation is completed, execute directly pip --version Let's make sure pip Is the installation successful , The results are shown below ：

   pip 22.2 from /home/esp/.local/lib/python3.8/site-packages/pip (python 3.8)
   

   There is the information shown above , On behalf of pip Installation is successful , Then continue to execute ./install.sh Script , It turns out that /home/esp/.espressif/python_env/idf5.0_py3.8_env/bin/python: No module named pip Error of , Mingming pip It has been installed successfully , How can this error be reported here .

   Get into ESP-IDF Of python Environmental Directory ~/.espressif/python_env/idf5.0_py3.8_env/lib/python3.8, Found under this directory site-packages There is no pip The catalog of , guess ./install.sh What you really want to use in the script is Espressif Self defined python Catalog , Not in ubuntu Specified on python Catalog .

   After the above analysis , There is only one solution , stay Espressif Self defined python Catalog ~/.espressif/python_env/idf5.0_py3.8_env/lib/python3.8 Under the site-packages Middle mount pip that will do . Execute the following two commands ：

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

   /home/esp/.espressif/python_env/idf5.0_py3.8_env/bin/python3 get-pip.py
   

   Query after execution site-packages Catalog , It is found that there is already pip Catalog . And then execute it again ./install.sh The script can be .
