To get some first ideas about V3.2, tried to compile hello example and got this

esp32@v12116:~/V3.2/esp-idf/examples/get-started/hello_world$ make
Toolchain path: /home/esp32/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc
Toolchain version: crosstool-ng-1.22.0-80-g6c4433a
Compiler version: 5.2.0
The following Python requirements are not satisfied:
cryptography>=2.1.4
Please refer to the Get Started section of the ESP-IDF Programming Guide for setting up the required packages. Alternatively, you can run "/usr/bin/python -m pip install --user -r /home/esp32/V3.2/esp-idf/requirements.txt" for resolving the issue.

Running python install as mentioned get this

Code: Select all

esp32@v12116:~/V3.2/esp-idf/examples/get-started/hello_world$ /usr/bin/python -m pip install --user -r /home/esp32/V3.2/esp-idf/requirements.txt

Cleaning up...

Looks to me like having 2 different methods to recognize cryptography
Looking into site-pacckages I see folder for cryptography and cryptography-2.4.2-py2.7.egg-info
Any idea whats going wrong ?

May be, this can help, I've to check viewtopic.php?f=13&t=7017&start=20
Since I didn't get any feedback, my quick and ugly solution up to now is to comment the check.
Couldn't recognize any restrictions (yet)

我找到了原因，应该是跟cryptography相关的依赖包没安装，可以通过下面的命令，来查找还有哪些依赖包没安装好

表示，ipaddress这个依赖包没安装
可以sudo python2.7 -m pip install ipaddress
然后再执行

表示cryptography已经安装成功了
执行make，不会报依赖包的错误
