Could you please try installing mbed-cli using pip e.g. pip install mbed-cli and if this doesn't work try installing Mercurial individually e.g. pip install Mercurial and send us the results. Thanks

When trying to install mbed-cli on a fresh Windows PC with Python 3.7, I get an error related to the mercurial dependency

 pip install mbed-cli

I understand there is no egg file in pypi hence it's asking to have MS Visual C++ installed. Same problem with Python 3.8 and 3.6

@madchutney Any resolution to this issue? It seems critical. This is affecting many people. I am also having this problem - see below.

WARNING: You are using pip version 19.2.3, however version 20.0.1 is available.

A workaround is to not install the latest version, but that takes some knowledge of this issue, which most users will not have.

pip install mbed-cli==1.10.1

[maclobdell]

@madchutney - please let us know if you have an update.

[madchutney]

@maclobdell We believe this was caused by a problem with pip and it should now have been resolved. Can you please check that this is still occurring?

[acabarbaye]

There was indeed an issue with pip a few weeks back #949 which made us think pip could be responsible for this isssue. Trying on my windows machine, pip install mercurial worked fine but actually, I just realised I have Microsoft Visual C++ installed. Trying on a separate Windows machine, I got the same error as you no matter what version of pip I use. Looking a bit more closely at what is distributed on PyPI for mercurial I realised that there is no wheel for python 3 (only for cp27 hence python 2.7). Therefore, pip needs to build the package at installation, which means it needs a C++ compiler installed as there is some C/C++ code in mercurial. Until mercurial is packaged and released as a wheel for python3, it will not be possible to install it on Windows without requiring users of python3 to install a compiler on their machine.

[MarceloSalazar]

We should really not require developers to install the C++ compiler as it's a massive package and impacts the UX to get started.
I hope we can have a wheel package for Python 3 soon and from there try to freeze the dependencies.

[madchutney]

Yes hopefully, Python 3 support is still in beta for Windows according to this page https://www.mercurial-scm.org/wiki/Python3
