This may be a known issue with encodings. If you are able to try the development version of pip from github, then please confirm if the problem still exists with that.

How to use dev version of pip?

Use python -m pip install git+https://github.com/pypa/pip.git to install it, then try running the same command and check if that fails. :)

Good news is, that pretty much confirms that it's an encoding issue (which is fixed in the latest version of pip). The bad news is that you can't use your current pip to upgrade itself because the current version has a bug :-(

I'm not sure what the best option is for a clean upgrade for you here. You could install by cloning the git repo and then using setup.py install but that's messy. I'll have a think and see if I can suggest an upgrade strategy for you.

I suspect that the problem is that your temporary directory includes your username, which is non-ASCII, and I suspect you're hitting an issue where the ANSI and OEM codepages set for Windows differ, which causes the sort of encoding issues you're seeing (and is what we've hopefully fixed in the next version of pip). A possible workaround would be to set the TEMP environment variable to a different value.

So one possible approach would be either to set TEMP to something like C:\Temp, which will let pip work at the cost of having to change your system configuration, or if you're OK with using an unreleased version of pip, getting the development version installed by doing:

mkdir C:\Temp
set TEMP=C:\Temp
python -m pip install git+https://github.com/pypa/pip.git
python -m pip --version

(The last command is to check that you now have the dev version of pip installed).

C:\Users\陈志祥>mkdir C:\Temp

C:\Users\陈志祥>set TEMP=C:\Temp

Hmm, OK. SO I think you're either going to have to wait for the next release of pip, or install manually from git, by:

  1. Manually remove your current copy of pip.
  2. Clone the github repository (or download the tarball of the master branch from github and unpack it).
  3. Run python setup.py install in the clone directory.

The code that's failing has been replaced in the development version of pip, so it's not really possible to diagnose any further until we confirm if the problem still exists in the development version.

Just one other thought - the final error says "Permission Error" (followed by some text in a language I'm afraid I don't know). Is your PC locked down in any way that means you might be refused permission to delete files that you created? It's possible that if your file permission settings are unusual, pip is not able to delete a file that it should be able to.

Another possibility is that if you have an aggressive anti-virus program, it could be locking some of pip's working files to scan them. You may want to try turning off your anti-virus program and try again.

@pfmoore Error 32 is "another process is using the file" .

Just one other thought - the final error says "Permission Error" (followed
by some text in a language I'm afraid I don't know). Is your PC locked down
in any way that means you might be refused permission to delete files that
you created? It's possible that if your file permission settings are
unusual, pip is not able to delete a file that it should be able to.

Ah - that could well be an anti-virus program in that case...

@chenzx
When I change cmd code page to 437, it success. Try like this:

chcp 437
pip install mitmproxy

I faced this issue and it was solved with

python -m pip install --upgrade pip

That installed pip 10

There has been a pip release with the fix so, you can now install pip using get-pip.py. :)

python -m pip install --upgrade pip
