NameError: name 'env' is not defined

Once added "lib_deps = ESP8266 IoT Framework" to the platformio.ini a working nodemcuv2 project fails to build.

NameError: name 'env' is not defined:

It might be related to the changes made in #71.

Can you open a PlatformIO terminal, execute the command pip install asn1crypto and then try again? If this resolves it I will look into a fix.

[roglio]

pip3 install asn1crypto installed the missing dependency but the error is still there.

[roglio]

PS: removing lib_deps = ESP8266 IoT Framework does not fix the issue. The project seems "corrupted".

[maakbaas]

Can you reproduce the issue in a new project? What version of the framework are you using, and what version of PlatformIO and the ESP8266 Arduino libraries?

[smartynov]

I'm having the same issue. Created an empty project from scratch (copying a "hello world" example). Using Atom 1.54.0 and PlatformIO Core, version 5.1.0 on MacOS 10.15.7, python 3.9.2.

[smartynov]

What helped me:

1. start Atom + platformio, open platformio terminal
2. type pio system info and locate "Python Executable" path in output
3. type /Users/myusername/.platformio/penv/bin/python -m pip install asn1crypto (starting with the path from system info)

(solution seen in issue #70)

@maakbaas

Can you reproduce the issue in a new project?

Yes: each time I start a new project. I can build it before adding the lib_deps.

What version of the framework are you using, and what version of PlatformIO and the ESP8266 Arduino libraries?

is a fresh install then I suppose the latest of both (in windows but also under linux I get the same behavior)

@smartynov

type /Users/myusername/.platformio/penv/bin/python -m pip install asn1crypto (starting with the path from system info)

this worked for me! under linux works either: ~/.platformio/penv/bin/python -m pip install asn1crypto

[roglio]

It works on windows too but the path it slightly different: c:\users\myusername\.platformio\penv\scripts\python.exe -m pip install asn1crypto

[maakbaas]

I have reworked the python script to resolve the initial env related error, so hopefully the manual pip commands are no longer needed :).

[roglio]

Still does not work :-(

Maybe there is a delay in the dependency distribution?

[maakbaas]

Sorry, I did not yet update the PlatformIO package.

You can test the latest changes by using

lib_deps = https://github.com/maakbaas/esp8266-iot-framework

in your platformio.ini.

[roglio]

Thank you! It works :-)
