This is crippling my workflow. Happy I exported and cloned my root env before upgrading to the latest "stable" version of anaconda.

Please see #6456 for more info and possible resolution.

This change was made because pip nested their vendoring more deeply in recent releases. In testing, we saw path length issues that broke things much worse than the issue you're seeing, and acted to remedy them by un-vendoring pip. This works for clean installs, but highlights a buggy legacy package. We can't fix the buggy legacy package - removing it always leaves the files that are causing issues.

[akapocsi]

Deleting "C:\Anaconda3\Lib\site-packages\pip" and subsequently forcing a re-installation with "conda install pip -f" fixed the issue for me.

[Gabrielvon]

@akapocsi Thanks a lot! It works like a charm!

[Gabrielvon]

@msarahan I am hardly understanding the #6456 professionally but your comment explained the problems to me. I got the direct solution from @akapocsi . Thanks for answering though.

[msarahan]

Sure, no problem. Sorry for not posting a more direct answer. Thanks @akapocsi for posting better instructions.

[Mereep]

I have the same issue as the Threadstarter with the exception I am using Windows 10.

I also followed the instruction stated by @akapocsi . It did not succeed. I stumble from one mess to another trying to install tensorflow-gpu.

The whole workflow seems broken from a to z.

[akapocsi]

@Mereep Why did you delete pip.exe?

The instructions I posted above indicate that you need to delete a folder, not a file.

[akapocsi]

@Mereep Try deleting "C:\Users\richard\Anaconda3\Lib\site-packages\pip" and subsequently forcing a re-installation with "conda install pip -f"

@akapocsi you're a genius! I was facing the same problem of @Gabrielvon and reading the issue #6456 didn't help me (I'm a Python newbie). These instructions solved my problems in less than 1 minute! Thank you!

[Mereep]

@akapocsi Yes, correct, I didn't notice that this is the site-package folder. And since the exe was recreated after that, I assumed it was the correct way. Thanks for that hint. Deleting the site-package node will actually work (partially).

While pip seems to at least start again, Installing packages (on my system) doesn't work still.

I also cannot upgrade pip itself using pip, since the error occurs then also. Should I open a ticket for that or does that look like a totally local problem?

[EDIT]
I digged a bit into that problem. If you change "transport_encoding" to just "encoding" at line 730 of the mentioned file, it seems to fix the problem. Transport encoding came into the repository with version "0.99999999/1.0b9" while the installed version in my anaconda (I upgraded all packages recently) is version "0.9999999"

[EDIT2]
Digged deeper. The html5lib-version missmatch comes from installing tensorflow via conda. This will downgrade html5lib and therefore will render pip unable to work since it depends on the API Change of the parse method. Ultimately, installing tensorflow on Windows 10 using conda will break pip.

Still no working environment. Really frustrating situation.

[Gabrielvon]

close issue.

Easy fix for windows users:

easy_install requests

[lafftar]

thank you @malhotravasu

FYI,

• the Anaconda global Python site-package location is C:\ProgramData\Anaconda3\Lib\site-packages
• but the individual environment site-package location is C:\Users\<user>\AppData\Roaming\Python\Python36\site-packages

So after you deleted pip directory but something is still wrong, maybe you have deleted the wrong directory.

How do I fix the error? ::
