Install throws CalledProcessError exit code 106 on windows 10

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Windows 10

• Poetry version: 1.0.5

Issue

After doing a clean install I run:

poetry init

no problem, toml is created as linked.

poetry install Creating virtualenv hyperpy-M0-5xabO-py3.8 in C:\Users\Johan\AppData\Local\pypoetry\Cache\virtualenvs [CalledProcessError] Command ‘[‘C:\Users\Johan\AppData\Local\pypoetry\Cache\virtualenvs\hyperpy-M0-5xabO-py3.8\Scripts\python.exe’, ‘-Im’, ‘ensurepip’, ‘–upgrade’, ‘–default-pip’]’ returned non-zero exit status 106.

Subsequent attempts at poetry install gives:

PS C:\Users\Johan\hyperpy> poetry install -vvv

I am aware of https://github.com/python-poetry/poetry/issues/1587 However Python 3.8 is installed through the store and works as expected:

PS C:\Users\Johan\hyperpy> where.exe python C:\Users\Johan\AppData\Local\Microsoft\WindowsApps\python.exe PS C:\Users\Johan\hyperpy> python Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)] on win32 Type “help”, “copyright”, “credits” or “license” for more information.

I had this issue in both Powershell and cmd.exe, and symlinking worked indeed.

For those who don’t how to symlink on Windows (i didn’t have a clue), you need to use cmd (not Powershell) then do this:

cd %LocalAppData%
rmdir /q /s pypoetry
mklink /d %LocalAppData%\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\Local\pypoetry pypoetry

There seems to be something of a path mismatch happening here.

Poetry makes the initial copy of the python executable to %LocalAppData%\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\Local\pypoetry\..., but subsequently expects the environment to be located at %LocalAppData%\pypoetry\....

Symlinking %LocalAppData%\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\Local\pypoetry to %LocalAppData%\pypoetry seems to work around the issue for me.
