"Unable to find vcvarsall.bat" error when trying to install rdflib-2.4.2 with Python 2.6.4 and Windows 7 x64 #104

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Try and install rdflib 2.4.2 using easy_install from the command prompt 
by issuing the command "easy_install -U "rdflib==2.4.2""

What is the expected output? What do you see instead?
- I expect that it will install smoothly.

- What I actually see is:

Searching for rdflib==2.4.2
Reading http://pypi.python.org/simple/rdflib/
Reading http://rdflib.net/
Best match: rdflib 2.4.2
Downloading http://rdflib.net/rdflib-2.4.2.tar.gz
Processing rdflib-2.4.2.tar.gz
Running rdflib-2.4.2\setup.py -q bdist_egg --dist-dir 
c:\users\brycet~1\appdata\
local\temp\easy_install-st4_nc\rdflib-2.4.2\egg-dist-tmp-qjaet5
warning: no files found matching 'example.py'
error: Setup script exited with error: Unable to find vcvarsall.bat

What version of the product are you using? On what operating system?
rdflib 2.4.2
Python 2.6.4
Windows 7 x64

Please provide any additional information below.
- I did some reading and found a suggestion to try installing the Visual 
C++ redistributable.  I found and installed both x86 and x64 versions of 
the redistributable but this did not change anything.  
- I read somewhere that an error somewhat similar to this existed in Python 
version 2.6.3 due to a regression but was fixed in Python 2.6.4.  Given 
that I'm running Python 2.6.4, this should not have affected me.

This will not be an issue in rdflib 2.5.x as we have switched to using pure 
python for the sparql parser 
implementation.

Good to hear that it won't be a problem in 2.5.x.

In the meantime I found a workaround which is to install minGW32 and compile it 
with 
that.  So for anyone with a similar problem:

1. Download minGW32 installer from sourceforge
2. When you install the tool and get the screen asking what components to 
install, 
select "MinGW base tools", "g++ compiler" and "MingW make".
3. After MinGW is installed, add C:\MinGW\bin to your Path environment variable
4. Create a file in C:\Python26\Lib\distutils and call it distutils.cfg
5. In this file, put the following:

[build]
compiler=mingw32

This way easy_install will try and use mingw32 as the compiler when you install 
rdflib.  

6. Run the easy_install command again:  easy_install -U "rdflib==2.4.2"

And hopefully you're all good.

This will no longer be an issue starting with rdflib 2.5.0. At this time, we 
are not planning on fixing this for 
2.4.x.

Alec - your bug has nothing to do with rdflib - you are in the wrong place :) 

Your solution is to install cygwin, and otherwise look at the mercurial 
homepage for mercurial support. 

Cheers,

可以看看http://www.ibaiyang.org/2012/07/15/python-trouble/

这个问题一般是因为我们的python2.7找的环境变量和我们安装��
�VS2010版本不一致导致的。。。
