Error after Install the Required Python Packages (IDFGH-860)

[dstasiuk]

Failed after installation requires:

error: command 'i686-w64-mingw32-gcc' failed: No such file or directory How I can fix this? Thank you.

Hi @StasiukDanylo. Could you please post also the beginning of the log. I'm particularly interested in seeing which Python dependencies are not met. Also please post the output of which python command. Thanks!

[ericd1949]

Excuse me from butting in, but I have also found this situation by following the "get-started" tutorial at: https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html I'm Windows 10 Pro, patched right up to date as of today. and I just followed the web instructions, I'm pretty sure :-)

My python info: $ python --version Python 2.7.14

which python /mingw32/bin/python

My path seems ok $ echo $IDF_PATH C:/msys32/home/erics/esp/esp-idf

As directed I used the python command, but it also failed in the same way if I used python2.7 I had tried it a few times, so some of the requirements were already met

Full log here and thanks in advance, Cheers, Eric

Hi @ericd1949,

Please try this command to resolve the issue: pacman -S mingw-w64-i686-python2-cryptography mingw-w64-i686-python2-pyparsing

If the previous one doesn't help then:

pacman -Sy pacman
pacman -Syu

[ericd1949]

Thanks for your very swift response and suggestions, I'm swimming in the dark, a bit, but I'll give you the info I have.

I ran the first pacman command, and it re-installed pyparsing and cryptography, then I ran make flash and it failed with: $ make flash Toolchain path: /opt/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc Toolchain version: crosstool-ng-1.22.0-80-g6c4433a5 Compiler version: 5.2.0 The following Python requirements are not satisfied: cryptography>=2.1.4 The recommended way ......

So I ran the last two pacman commands you gave me, then the first again and got the same failure when I tried to make flash.

I also ran: $ python -m pip install --user -r $IDF_PATH/requirements.txt and got the same failure as I gave in my first report.

Could it be that the cryptography version I have (1.9-1), is not sufficient for my apparent requirements (2.1.4) ?

C:/msys32/home/erics/esp/esp-idf/requirements.txt has cryptography>=2.1.4

and

$ pacman -Ss cryptography mingw32/mingw-w64-i686-libbotan 2.3.0-1 Botan is a C++ cryptography library released under the permissive Simplified BSD license (mingw-w64) mingw32/mingw-w64-i686-python2-cryptography 1.9-1 [installed] A package designed to expose cryptographic recipes and primitives to Python developers (mingw-w64) mingw32/mingw-w64-i686-python3-cryptography 1.9-1 A package designed to expose cryptographic recipes and primitives to Python developers (mingw-w64) mingw64/mingw-w64-x86_64-libbotan 2.3.0-1 Botan is a C++ cryptography library released under the permissive Simplified BSD license (mingw-w64) mingw64/mingw-w64-x86_64-python2-cryptography 1.9-1 A package designed to expose cryptographic recipes and primitives to Python developers (mingw-w64) mingw64/mingw-w64-x86_64-python3-cryptography 1.9-1 A package designed to expose cryptographic recipes and primitives to Python developers (mingw-w64)

I also tried the pacman suggestions given when make flash fails, so I've got yards (or meters) of logs, let me know anything else you need.

Cheers, Eric

[dobairoland]

Yes @ericd1949, that is the problem. The installed package is too old. The following command I gave you before should update the packages:

pacman -Syu

Can you please post the output of this command?

[ericd1949]

Ok, this is it: $ pacman -Syu :: Synchronising package databases... mingw32 is up to date 0.0 B 0.00B/s 00:00 [---------------------------------------] 0% mingw64 is up to date 0.0 B 0.00B/s 00:00 [---------------------------------------] 0% msys is up to date 0.0 B 0.00B/s 00:00 [---------------------------------------] 0% :: Starting core system upgrade... there is nothing to do :: Starting full system upgrade... there is nothing to do

I tried doing a make flash again , just in case some change had happened, but it fails in the same way

Thanks.

[dobairoland]

@ericd1949, I don't understand how this could be because after pacman -Sy the cryptography package should be of version 2.6. Your package database doesn't get updated for some reason. It seems to me some issue with MSYS2 and not IDF.

Can you try the MSYS2 ZIP file available from here: https://docs.espressif.com/projects/esp-idf/en/latest/get-started/windows-setup.html#toolchain-setup That should work.

[ericd1949]

Ok I will do that. The file I had downloaded on 1st April was: esp32_win32_msys2_environment_and_toolchain-20180110.zip I'll let you know, there is some serious de-zipping to be done :-)

Cheers, Eric

[ericd1949]

Great, that fixed it - Hello World flashed and talking, changed a bit, re-compiled, and talking some more. For the sake of info the MSYS file I downloaded was: esp32_win32_msys2_environment_and_toolchain-20181001.zip and having unzipped it to C: I just copied my home directory from my old msys32, as on the instructions.

Thanks for your quick responses and help, I may rest a bit before trying to get it to work in Eclipse :-)

Cheers, Eric

[dobairoland]

I'm happy that it got resolved.

How about you @StasiukDanylo? Did your issue got resolved as well?

[mbermingham22]

Hello, I'm having the same problem as described in this thread. Except nothing listed here is clearing the "i686-w64-mingw32-gcc failed" error. pacman doesn't think there is anything to do (i.e. everything is up-to-date).

Hi @mbermingham22. The log shows that the version of your cryptography package is old (1.9). You need to update the packages by pacman -Syu.

The file "exists in filesystem" errors indicate that the given package cannot be installed by pacman because it was installed by pip. Try to remove it by pip uninstall pycparser and then install it by pacman -S mingw-w64-i686-python2-pycparser.

[mbermingham22]

I tried that...here's what I had.

$ pacman -Syu :: Synchronizing package databases... mingw32 is up to date 0.0 B 0.00B/s 00:00 [---------------------------------------------] 0% mingw64 is up to date 0.0 B 0.00B/s 00:00 [---------------------------------------------] 0% msys is up to date 0.0 B 0.00B/s 00:00 [---------------------------------------------] 0% :: Starting core system upgrade... there is nothing to do :: Starting full system upgrade... there is nothing to do

I'm trying to uninstall and reinstall pycparser, we shall see how that goes.

[mbermingham22]

Okay, did all of that, and it keeps re-installing v1.9 of cryptography. How do I force it to install the new one?

Oh, I see. If these commands didn't help you then probably the only option is to download the new zipped MSYS2 environment: https://docs.espressif.com/projects/esp-idf/en/latest/get-started/windows-setup.html#toolchain-setup.

can you please hlep

[dobairoland]

Hi @naznaaa. Please run make menuconfig, go into menu "SDK tool configuration" and make sure that the "Python 2 interpreter" is python and not pytho.

[naznaaa]

Great,it's fixed
