Testing Octopress and Ruby 2.0 on Windows 7 (3)

Background

I was writing my previous post, which was about my recent Mik$\rm \TeX$ update.

Problem

After having finished it, I tried rake generate, and got results similar to the first picture of the first post in this series.

Last time, I solved this problem by creating the batch file python2.bat in the folder where Python had been installed (i.e. C:\Python27). This time, the BAT file is already there. In (Git) CMD, both which python and which python2 are fine. However, in Git bash, I run into trouble.

Even though the generated contents can still be locally previewed, how can I get rid of this error message?

Solution

I googled “which no python2 in” (with surrounding double quotes), and found one line in the post Jekyll on Windows With Cygwin written by Nathan Story very useful. While reading his post, I didn’t read it from the start. Instead, I just searched for “python2”, and quickly saw the ln command.

The file type of python2 created by ln was different from what I expected: ls -l didn’t show that python2 was a symbolic link, and file even said that it was an executable file.

$ ln -s python.exe python2

Owner@Owner-PC MINGW64 /c/Python27
$ ls -l

$ file python2
python2: PE32 executable (console) Intel 80386, for MS Windows

Finally, rake doesn’t give me strange output.
