Hi,

I get an installation error when trying to install "scons" under Windows 10 x64. 😭
Other packages seem to be installed properly.

According to this SO thread the problem disappears by using the flag "--egg".

However, I know only very little about python and its environment and wouldn't say that this is a "proper" solution to this problem but at least it worked for me. Maybe there are some of you with similar problems. Just in the case of a more general problem it would be nice to put it somewhere in the docs.

Here's the command I used to install "scons".

pip install -U pip setuptools --egg scons

And here's the proof 😄

[ivankravets]

Thanks, sorry! I've just changed these lines in documentation. Firstly, need to upgrade pip and setuptools to the latest version and then install scons and platformio.

You won't need to install scons when PlatformIO 2.3.0 will be released.

[brakmic]

Many thanks 👍

[ivankravets]

Which source did you use when install PlatformIO? Home site or documentation?

See updates: http://docs.platformio.org/en/latest/installation.html#python-package-manager

[brakmic]

I used the tutorial from homesite but can't remember which version it was. I've installed it just an hour ago.

http://platformio.org/#!/get-started

[ivankravets]

Thanks. The site has been updated too http://platformio.org/#!/get-started

You said earlier that scons would not be required anymore in 2.3.0 but it is still in your requirements.txt.

[ivankravets]

@sarfata Don't install packages using --egg. You won't have ability to uninstall them properly later.

1. Have you had install PlatformIO earlier?
2. You should upgrade pip to the latest version:

pip install -U pip setuptools

# then
pip install -U platformio

[sarfata]

Yes I had platformio before and it was working. I started having problems when I tried to update yesterday.

Pip and setuptools are already up to date:

[ivankravets]

@sarfata please give me an output of this command:

pip list

P.S: This issue with error: option --single-version-externally-managed not recognized was fixed in pip 7.0. It seems that you have pip < 7.0 version. Try to upgrade pip directly:

python -c "$(curl -fsSL https://bootstrap.pypa.io/get-pip.py)"

P.S.S: Do you use virtualenv?

[martenlienen]

Edit: I repeated the steps on a clean install and updated the shell log above.

[ivankravets]

It seems that I've found where this issue is hidden. Give me please a whole GLOBAL LIST with installed packages(not from virtual environment). If one package depends on pip<7, pip will use it for the rest packages. New version of PlatformIO requires pip>=7 and new setuptools. I've just reproduced this issue in my virtual machine (Linux Ubuntu). Here virtualenv package is used old version of pip/setuptools. The

[sudo] pip install -U setuptools

resolved my issue.

Do you have installed virtualenv package?

[martenlienen]

Yes, I am using pyenv-virtualenv. I will uninstall all other packages and try it again without a virtualenv.

[ivankravets]

Just upgrade GLOBAL packages to the latest versions:

[sudo] pip install -U pip setuptools virtualenv

[martenlienen]

The problem persists outside any virtualenv. log. And virtualenv is not even installed now.

[ivankravets]

@cqql please try development build:

pip install https://github.com/platformio/platformio/archive/feature/issue-279.zip

P.S: If error still exists, try "twice" command above. Please report me results.

[martenlienen]

The error persists (log). Did you mean to try the installation twice? The quotes confused me. Trying it twice did not help.

I put some print statements in my pip installation and verified, that it is indeed running 7.1.2 and it passes --single-version-externally-managed to the setup.py every time --egg is not given. But somehow SCons' setup.py does not understand that option.

[ivankravets]

@cqql Thanks that help me to resolve this issue. I can switch to previous logic (PlatformIO <2.3), where scons has installed via pip install --egg scons, but it isn't good solution. SCons team works on it. This isn't problem of PlatformIO. PlatformIO depends on SCons. The installation process of SCons was fixed in pip>7andsetuptools>=16.

I revert code to previous logic (based on --egg) if we will not found common solution. Currently, only Linux users have these problems.

Please try this build 3189a9d:

pip install https://github.com/platformio/platformio/archive/feature/issue-279.zip

[martenlienen]

I do not like scons. This is the second scons related issue I ran into (the other happened several months ago) and both times it took both of us a few hours to sort it out.

I tried installing the new build, but to not avail. It is still the same error. I instrumented my pip again with some print statements in req/req_install.py right before the command is called to check the versions

with indent_log():
    import setuptools
    import pip
    print(setuptools.__version__, pip.__version__)          
    call_subprocess( 
        install_args + install_options,
        cwd=self.source_dir,
        show_stdout=False,
    )

and the versions are

So apparently it is still not working.

[ivankravets]

Thanks. Try 3-rd build 07e49cd:

pip install https://github.com/platformio/platformio/archive/feature/issue-279.zip

SCons has been removed from dependencies. Now install it via:

pip install --egg SCons

[martenlienen]

That works. Thanks a lot. But of course it would sure be nicer, if scons could be declared as a dependency. Do you have an idea, why it broke, although the scons developers already worked on this issue?

[ivankravets]

Do you have an idea, why it broke, although the scons developers already worked on this issue?

They have worked on it a few years... I don't know what SCons uses in the kernel, but it is intended to be installed via OS package managers(not via pip). I asked them a few weeks ago to update scons package in PyPi, because PyPi had contained the packages from 2013 year. Now we have the latest 2.3.6 in the PyPi.

---

You machine looks good to learn this issue. If you are ready we can try to find solution. First, let's use virtualenv:

pip install -U pip setuptools virtualenv
cd /tmp
virtualenv piotest
source piotest/bin/activate
pip list
pip install scons

Give me please a log of these commands.

This is virtualenv... I had the same behaviour :( Strange behaviour. I can add to existing installation virtualenv, but I needn't it. Other solution, to add "Warning" block where propose to update pip install -U pip setuptools virtualenv when error: option --single-version-externally-managed not recognized occurs.

WDYT?

P.S: Here we have another problem - scons --version doesn't work. However, it seems that I can fix it for scon from PlatformIO's side. Give me a few minutes.

[martenlienen]

It works for me

$ scons --version

Do you think, it was caused by an outdated virtualenv? I cannot believe that, because I tried it with a fresh install of virtualenv and I even cleaned all my python installations and started anew with 2.7.10. The only thing that changed from 2 hours ago is, that my laptop was suspended for 2 hours.

[ivankravets]

Try to downgrade virtualenv:

pip uninstall scons
pip install "virtualenv==1.3"
pip list
pip install scons

Have you reproduced issue again?

P.S: scons works for you because you use pyenv. However, it doesn't work when is installed to /usr/local/*.
P.S.S: I see that in previous reports you have used Python 2.7.9. An in the latest, you used Python 2.7.10. Could I ask you to try with Python 2.7.9?

[sarfata]

I see we are making lots of progress. Just wanted to say that I am on Mac OS so this is not a Linux only problem. And I do have pip >7:

Installing your 3rd build (07e49cd) also worked.

[ivankravets]

@sarfata could you try to install directly without virtualenv?

pip install platformio

[martenlienen]

It just works in every combination. I also tried to do it without virtualenvs, but as long as pip and setuptools are updated, everything works. However, why did it not work this afternoon?

Here are some logs though they are not really interesting.

[sarfata]

@ivankravets It just worked now (including installing Scons). I am not sure what changed before ... Sorry about that and thanks for your support!

[ivankravets]

@cqql @sarfata does PlatformIO work entirely? Can you build any projects via platformio run?

[sarfata]

@ivankravets yes it does.

[martenlienen]

platformio run just installed a program on my arduino without problems.

I reproduced this issue again and temporary solution is described in the original #279 (comment)

It looks stupid/magic for me, but I don't have other options. If someone will find more accurate solution, please report here.

PlatformIO 2.3.2 will be released today.

This "known issue" has been added to main docs:

• http://docs.platformio.org/en/latest/installation.html#python-package-manager
• http://docs.platformio.org/en/latest/faq.html#faq-troubleshooting-sconssingverextmanaged

I am running into this issue with PlatformIO 2.3.2 on Windows 10. However, pip won't install scons either. I can install scons via their distribution using setup.py or --egg. Even after doing so I still can't install platformio due to this error. Pip list does not show scons present. Scons --version reports 2.3.6.

[robotdad]

I was able to install using the get-platformio.py script.

[ivankravets]

@robotdad thank for the report! Have you used PlatformIO before 2.3 release?

[robotdad]

Yes, I have 2.2 on another machine which is working fine but I'm getting this error on trying to upgrade. I can't recall if it was updated from previous versions or not.

[ivankravets]

@robotdad give me please an output of this command (where platformio upgrade command doesn't work):

pip list

[robotdad]

bottle (0.12.8)
click (5.1)
colorama (0.3.3)
lockfile (0.10.2)
pip (7.1.2)
platformio (2.2.2)
pyserial (2.7)
requests (2.7.0)
setuptools (18.3.1)
virtualenv (13.1.2)

Also, scons --version reports 2.3.6

Thanks @brakmic for the solution at the top of this page. I dusted off a computer with an old version of platformio on it, and following the prompts caused it to become broken. Your solution fixed it for me.

[pastcompute]

I had this same problem, under Xubuntu 14.04 LTS. Except nothing I tried from above would get past the external version error.
In the end I had to do the following:

• removed everything under /usr/local/.../python... including platformio and all the other pip installed python packages
• uninstall the Ubuntu version of pip
• install pip as per https://pip.pypa.io/en/stable/installing/#python-os-support
  After this, pip install platformio worked again

[ivankravets]

@pastcompute, thank you, I added your comment to "solutions" list above.
