Installation failure on Windows 7: "CONDA_EXE not found. Reverting to default in ROOTENV" #217

omlins · 2022-04-06T15:14:49Z

When I try to install Conda.jl on a fresh Julia installation on Windows 7, the following happens:

@stevengj : would you have a workaround for this? I have seen that you had workarounds for similar issues in the past... :)
(I don't know my way at all around the Windows shell, etc, which makes it very difficult for me to analyse what is going on)
Any help is much appreciated as Conda.jl is a key dependency in a recent package I am developing:
https://github.com/omlins/JustSayIt.jl/

stevengj · 2022-04-06T16:50:18Z

Does C:\Users\somlin\.julia\conda\3\Scripts\conda.exe exist? Or is there a conda.exe in some other subdirectory of C:\Users\somlin\.julia\conda\3\Scripts?

Maybe they moved where they put the conda.exe file in recent versions?

stevengj · 2022-04-06T16:51:52Z

You might want to delete abspath(first(DEPOT_PATH), "conda", "deps.jl") to remove the results of any failed previous installation attempts before trying to re-build.

omlins · 2022-04-06T17:04:00Z

@stevengj : thanks a lot for your reply!

The content of .\conda\3 is:

omlins · 2022-04-06T17:10:05Z

@stevengj : you can see that there is _conda.exe (with an _!). Would that be what is supposed to be conda.exe?
The folder C:\Users\somlin\.julia\conda\3\Scripts does not exist.

omlins · 2022-04-06T17:13:36Z

You might want to delete abspath(first(DEPOT_PATH), "conda", "deps.jl") to remove the results of any failed previous installation attempts before trying to re-build.

Before every try, I deleted the whole C:\Users\somlin\.julia

By the way the DEPOT_PATH is:

julia> DEPOT_PATH
3-element Vector{String}:
 "C:\\Users\\somlin\\.julia"
 "C:\\Users\\somlin\\AppData\\Local\\Programs\\Julia-1.7.2\\local\\share\\julia"
 "C:\\Users\\somlin\\AppData\\Local\\Programs\\Julia-1.7.2\\share\\julia"

omlins · 2022-04-06T17:24:31Z

So as a test, I created the folder /C:\Users\somlin\.julia\conda\3\Script and copied _conda.exe inside and renamed it to conda.exe. Then, the result is this:

@stevengj : with PYTHON="" set, where is it supposed to get the Python library from when things work as they should?

omlins · 2022-04-06T18:05:39Z

I run C:\Users\somlin\.julia\conda\3\installer.exe, which turns out to be the miniconda installer. The installation completed, however there was an error "creating some menu entries", which I ignored. Then, the installation details show a problem with the Python library as in the installation triggered from Julia:

The full Python library error message that appears in the screenshot is:

Error loading Python DLL 'C:\Users\somlin\AppData\Local\Temp\_MEI47402\python39.dll'.
LoadLibrary: The specified module could not be found.
Error loading Python DLL 'C:\Users\somlin\AppData\Local\Temp\_MEI179482\python39.dll'.
LoadLibrary: The specified module could not be found.

The result is what seems to be the same incomplete installation as when installing from within Julia:

It seems to me that the installer automatically selected by Conda.jl does not work for Windows 7.
On the website of MiniConda it says (https://docs.conda.io/en/latest/miniconda.html):

Operating system: Windows 8 or newer, 64-bit macOS 10.13+, or Linux, including Ubuntu, RedHat, CentOS 7+, and others.
If your operating system is older than what is currently supported, you can find older versions of the Miniconda installers in our [archive](https://repo.anaconda.com/miniconda/) that might work for you.

I will try with an installer from the archive.

It looks like I could successfully install MiniConda3 - Python 3.7 into C:\Users\somlin\.julia\conda\3:

As a result, rebuilding PyCall seems to have worked correctly:

I guess that means that Conda.jl should therefore not use the newest installer for Windows 7 and before. What worked for me with Windows 7 was:
Miniconda3-py37_4.10.3-Windows-x86_64.exe from https://repo.anaconda.com/miniconda/

Note: I tried only this one, which is the oldest of MiniConda 3, and two with Python 3.9, which did not work.

@stevengj : I confirm that Conda.jl works for me as it should with this manual installation of MiniConda:

I guess that is all from my side.

My conclusion was in the previous comment:

Windows 7 officially reached its "end of life" 2 years ago according to Microsoft, so I guess it's not surprising that Miniconda apparently stopped supporting it.

Sure. One more thought: for this and other cases, it might be good to have a sanity check of the miniconda installation, checking that the expected files are there, as e.g. 'conda.exe'; then, if the installation was broken, give an appropriate error message.

A PR giving better error messages would be great.
