Installation step 2: not a valid identifierline 89: export: `sha1

Hi Team,

Following Step 2: Getting the esp-idf repository from github of the installation process on Windows 7 x64, I got the following two messages regarding sha1 (at the end of the full log below):

$ git clone --recursive https://github.com/espressif/esp-idf.git

I have tried this step twice with the same result.

The /esp-idf/components/esptool_py/esptool directory contains some files and sub directories.
I did not find any leads to this error on https://github.com/themadinventor/esptool repository.

Should I be concerned?

Hi @krzychb,
Until u got solution from esp32 team,try cloning git by desktop git app.I had some issue too but with desktop git app it worked.

Seen this message on colleague's windows computer as well. It looked like everything was actually checked out correctly.
Here's a similar error mentioned in msys2 tracker: msys2/MSYS2-packages#30. My guess that that's something with msys2 git, we'll check it...

(Deleted previous comment because I can reproduce this without any special directories, etc.)

I can confirm @igrr's comment that despite this error everything seems to work fine and the git submodule checkout is 100% valid. So it's nothing you have to worry about for now, provided esp-idf works as expected.

I did notice this path is directly in the msys "root":

Cloning into '/esp-idf/components/esp32/lib'...

Did you mean to run the git checkout from the directory /? (this corresponds to c:\msys32 in Windows). It's OK if you did, just wanted to be sure this isn't unexpected behaviour.

@hardikharpal, @igrr, @projectgus - thank you guys for really quick replies and support.

@projectgus - indeed I did git checkout intentionally from '/'.

From deciding to set up the esp-idf to getting esp-idf-template compiled, took me maybe 45 minutes. To get to this point with ESP8266 1.5 years ago has not been so easy for me and I was not sure what to expect now from ESP32 framework. ESP32 Team made it it really accessible and easy to follow.

Congratulations 😄 👍

Thanks for the kind words, that's exactly the kind of result we are all aiming for!

I've added a note in our Windows documentation about the weird submodule messages, with a link to this issue. There may eventually be a solution, but at least it's not breaking any functionality.
