Error on Windows: "TypeError: Can't mix strings and bytes in path components"

[umutzd]

I tried installing on Windows 10 by using these commands:

git clone https://github.com/juj/emsdk.git cd emsdk ./emsdk install sdk-incoming-64bit binaryen-master-64bit ./emsdk activate sdk-incoming-64bit binaryen-master-64bit

And it failed after a lot of attempts with the same errors again:

CMake Deprecation Warning at CMakeLists.txt:14 (cmake_policy):
The OLD behavior for policy CMP0051 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

CMake Warning at CMakeLists.txt:39 (message):
Visual Studio generators use the x86 host compiler by default, even for
64-bit targets. This can result in linker instability and out of memory
errors. To use the 64-bit host compiler, pass -Thost=x64 on the CMake
command line.

Also this running this command will throw some errors as expected:

Thanks, this was a Python 3 issue. Fixed in above commit.
