Are you able to open this file by hand in Notepad.exe (or any other editor)? It seems weird that this file cannot be read; this may be an environment issue, not a pip bug (although we should catch it and improve the error message).
I wonder why we’re suddenly seeing this in 20.2; there’s nothing new in the check operation AFAICT. Did something change in pkg_resources
? Can this somehow be related to #8054?

Hi @KishoreKumarRV ,
As per the above comment, could you also try installing pip from the latest master branch, (pip install https://github.com/pypa/pip/archive/master.zip
) and see if that resolves the error.
There was a regression bug which might have been introduced by the above PR which was fixed by https://github.com/pypa/pip/pull/8659, and could be the cause of this bug.
I get the same error too. I get it with basically any package, here I tried to install pyinstaller

FileNotFoundError: [Errno 2] No such file or directory: 'c:\\users\\ar_hv\\anaconda3\\lib\\site-packages\\s3transfer-0.3.3.dist-info\\METADATA'
I tried opening the file by hand and realized that inside anaconda3 I don't have a folder named "lib" just one named "Lib". This is the path for the file C:\Users\ar_hv\anaconda3\Lib\site-packages\s3transfer-0.3.3.dist-info\metadata.json
. I don't know if that's supposed to be the file but is the only one I found.
I appreciate your help
Case does not matter in Windows paths, so Lib
and lib
are equivalent. So you only have metadata.json
, but not METADATA
(no extension)?
Are you able to open this file by hand in Notepad.exe (or any other editor)? It seems weird that this file cannot be read; this may be an environment issue, not a pip bug (although we should catch it and improve the error message).
Can _anyone_ here saying you have this problem try to do this?
Sorry, I've been on vacation. That file doesn't even exist in my case. The path only exists till "site-packages". It's probably not a pip error, it's my fault.
If @Adrianahuante’s observation is correct, this is probably pip’s fault, not yours (i.e. if pip correctly installs some files for the distribution but not all). I wonder if this has something to do with the change in 20.2 that wheels are now installed directly from the archive.
Yes @uranusjr , in that folder I have two files: DESCRIPTION.rst and metadata.json. I don't have the METADATA file (with no extention)
Hmm, that does look a lot like a wheel installation failed half-way. So there are three issues here:
METADATA
optional in .dist-info
(for entirely unrelated reasons), and this would be a good chance to implement it. But the logic is in pkg_resources
, and since upstream fixes probably won’t land soon (new setuptools is Python 3-only, pip is currently vendoring an old version of it), we’ll need to do vendor-patching.I don't know what went wrong in the installation but I unistalled anaconda and installed it again. That solved the problem, although now I don't have the folder C:\Users\ar_hv\anaconda3\Lib\site-packages\s3transfer-0.3.3.dist-info
Thanks!
To folks facing this issue, could you provide some context on how to reproduce this failure?
Does this require interrupting the installation in an earlier run to cause failures in subsequent runs?
It is always preferred to install TF using conda and not 'pip' because it causes dependencies issues.
I faced the same problem when I tried to install TF using 'pip' inside a 'conda' env.
For a temporary fix, I created the missing files inside the file named 'METADATA' (with no extension) and it ran without any error.
Idk how reliable the solution is, but yes it worked for me.

@immohann, have you tried pip --use-feature=2020-resolver

@r3k2, could you please check if the problem persists using the latest version of pip from PyPI? Something might went wrong during your distro's devendoring process.

I try with another path and get it:
@KishoreKumarRV Did you have prompt-toolkit
installed before pip install --upgrade scipy
? If so, did prompt-toolkit
install successfully?
@uranusjr I tried pip install --upgrade scipy
and it is still giving me the same error
Here’s some context for people landing in this issue. The error is generated during the “integrity check” phase after packages are installed, and the fact that you hit this indicates that the packages you want have all been correctly installed. You can safely ignore this message if you must.
The easiest way to work around the error is to delete the offending .dist-info
directory in your environment. The last line of the error message should contain something like
FileNotFoundError: No such file or directory: /some/path/to/package-version.dist-info/METADATA
Steps to recover:
package-version.dist-info
directorypip install --force-reinstall package==version
Still having same issue .. why has it been closed?
It's fixed in #8926 which has now been merged to master. We close issues once a fix is in master, the fix will be available in the next release of pip.

What does this mean? How do I get the fixed version of pip and install it?
What does this mean? How do I get the fixed version of pip and install it?
You can either wait for the next official release of pip, and upgrade when it's out, or you can install pip from github if you're comfortable doing that (python -m pip install --upgrade git+https://github.com/pypa/pip
, but be aware that you are getting the "work in progress" unreleased version of pip).
This is released as part of pip 20.2.4 now. Upgrading to the newest pip will include the fix.
I am still facing the same issue with newer pip(20.2.4)
