Python：安装未来模块时出错

Question

Here is my configuration : Windows 7 64 bits, Python 3.5.3 64 bits

I am trying to install future-0.16.0.tar.gz via the setup file (can't use pip because I am not connected to the Internet), and I get this error :

*...byte-compiling build\\bdist.win-amd64\\egg\\libfuturize\\fixes\\fix_add__future__imports_except_unicode_literals.py to fix_add__future__imports_except_unicode_literals.cpython-35.pyc

error: [Errno 2] No such file or directory: 'build\\bdist.win-amd64\\egg\\libfuturize\\fixes\\__pycache__\\fix_add__future__imports_except_unicode_literals.cpython-35.pyc.69344256'*

Just to check, I have tried to install the future module with Python 3.5.3 32 bits and have encountered any problem at all. But for a problem of Oracle client, I can't use the win32 version... So I am stuck...

Does someone have an idea of where this comes from?

Thanks.

Answer 1

Thanks to the team that works on future, I had my answer.

The problem was I reached the MAX_PATH (The maximum character length of a path) of Windows. That "simple"!

So I copied the source files locally, and installed them. Problem solved.

Python was not guilty! And the work can go on...
