- 按以上文章执行，但没有完全下载完 esp-idf.
- 在mingw32窗口内执行
$ python -m pip install --user -r $IDF_PATH/requirements.txt3. 提示如下：
$ python -m pip install --user -r $IDF_PATH/requirements.txt

No working compiler found, or bogus compiler options passed to
the compiler from Python's standard "distutils" module. See
the error messages above. Likely, the problem is not related
to CFFI but generic to the setup.py of any Python package that
tries to compile C code. (Hints: on OS/X 10.8, for errors about
-mno-fused-madd see http://stackoverflow.com/questions/22313407/
Otherwise, see https://wiki.python.org/moin/CompLangPython or
the IRC channel #python on irc.freenode.net.)
Trying to continue anyway. If you are trying to install CFFI from
a build done in a different context, you can ignore this warning.

因为之前下载的 esp32_win32_msys2_environment_and_toolchain-20180110.zip 里面缺 ..\msys32\mingw32\bin/i686-w64-mingw32-gcc.exe
4. 只好在百度里找，下载如下gcc.

把如下两个目录里的内容复制到 mingw32的安装目录 ..\msys32\mingw32\：
5. 再次 运行 make
提示：
Toolchain path: /opt/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc

The following Python requirements are not satisfied:
future>=0.15.2
cryptography>=2.1.4
pyparsing>=2.0.3
pyelftools>=0.22
The recommended way to install a packages is via "pacman". Please run "pacman -Ss
NOTE: You may need to run "pacman -Syu" if your package database is older and run twice if the previous run updated "pacman" itself.
Please read https://github.com/msys2/msys2/wiki/Using-packages for further information about using "pacman"
WARNING: The cryptography package have dependencies on system packages so please make sure you run "pacman -Syu" followed by "pacman -S mingw-w64-i686-python2-cryptography".
Alternatively, you can run "D:/ESP32/msys32/mingw32/bin/python.exe -m pip install --user -r D:/ESP32/esp-idf/requirements.txt" for resolving the issue.
make: *** [D:/ESP32/esp-idf/make/project.mk:245：check_python_dependencies] 错误 1
6. 按提示 运行 pacman -Syu" followed by "pacman -S mingw-w64-i686-python2-cryptography
