markupsafe: Won't install on Windows

Actually, the problem seems to come from missing wheel for MarkupSafe on Pypi. Creating it manually solved the issue for me. Here is the workaround (I use git-bash on Windows):

git clone git@github.com:pallets/markupsafe.git /c/tmp/markupsafe
cd /c/tmp/markupsafe
./setup.py bdist_wheel

The result is a valid wheel: /c/tmp/markupsafe/dist/MarkupSafe-1.0-cp36-cp36m-win_amd64.whl. In your other project where you need to use it, simply call

pip install /c/tmp/markupsafe/dist/MarkupSafe-1.0-cp36-cp36m-win_amd64.whl

And you’re done

Here is a simple solution. Since it is a decode error, it can be solved by changing the console’s coding to utf-8. Just run

chcp 65001
pip install markupsafe

and it works.

@OlegBrony It seems that Markupsafe is failed to build and install, but pip thinks it is already installed after the unsuccessful install. Maybe this issue only appears in Virtualenv environment. Please try to uninstall, ‘chcp 65001’, and install it again.

I also meet this question, I found this is just a decode error. In my environment， the console’s coding is ‘gbk’, and this return s.decode(‘utf-8’). so it make error. when I modify the source code to s.decode(‘gbk’). It works.

Traceback (most recent call last):

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 33: invalid start byte

During handling of the above exception, another exception occurred:

I had the same error with Python 3.6 on Windows 10 and @alorence’s solution fixed it.

I also saw this error. But I upgraded my pip to 10.0.1 and resolved problem. My pip verson is pip 10.0.1 from python 3.6 I’m using WIndows 10 now.

I used “git bash” for reinstalation markupsafe and it helped me. No one UnicodeDecodeError

In case someone do have my issue:

@alorence’s solution fixed it all. Kudos to him for fixing an hours long issue.
