53.1 introduction

Today, we set up the esp8266 development environment of Anxin technology in the Ubuntu environment. When we went to the configuration step, a problem occurred. We checked it online, but it was not actually solved. Later, we found that the foreign blog encountered the same problem as me. We solved it by referring to his practice. This is hereby recorded to make up for the lack of integrity of the Chinese blog’s solution to this problem.

53.2 problems

The configuration compilation problem is as follows:

qihua@qihua-virtual-machine:~/esp/setuptools-19.2$ sudo pip install setuptools -U

You are using pip version 8.1.1, however version 21.2.4 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

According to the above prompt, it is caused by the low version of PIP tool. As long as you run PIP related commands, an error will occur.

sudo python -m pip install --user -r $IDF_PATH/requirements.txt

You should consider upgrading via the 'pip install --upgrade pip' command.

However, follow the prompts to execute the upgrade instruction: PIP install — upgrade pip   After, it’s useless. It’s not updated to.

53.3 solution

After a review, the command to automatically upgrade PIP (as follows) failed. It may just match the version used in the current environment.

pip install --upgrade pip

Then, upgrade pip to a higher version by specifying the upgrade version. The command is as follows:

pip install --upgrade pip==20.3

After upgrading pip, I also upgraded the setuptools tool.

qihua@qihua-virtual-machine:~/esp/setuptools-19.2$ python -m pip install --upgrade setuptools
