如何在Python中获取已安装的GIT的路径？
我需要使用 Python 2.6.1 将 Max OS X 10.6 上的 GIT 路径放入脚本变量中。我使用此代码：
r = subprocess.Popen(shlex.split("which git"), stdout=subprocess.PIPE)
print r.stdout.read()
但问题是输出为空（我也尝试过 stderr）。它可以与其他命令（例如 pwd 或 ls）配合使用。
有人能帮我吗？
更新：当我从终端运行 which git 时，它会按预期打印出路径。所以，which 可以找到它。
更新 2：我刚刚创建了 bash 脚本
#!/usr/bin/env bash
GP=`/usr/bin/which git`
PWD=`pwd`
echo "PATH IS: ${GP}"
echo "PWD IS: ${PWD}"
，输出是
PATH IS:
PWD IS: /Users/user/tmp
I need to get a path to the GIT on Max OS X 10.6 using Python 2.6.1 into script variables. I use this code for that:
r = subprocess.Popen(shlex.split("which git"), stdout=subprocess.PIPE)
print r.stdout.read()
but the problem is that output is empty (I tried stderr too). It works fine with another commands such as pwd or ls.
Can anyone help me with that?
UPDATE: When I run which git from Terminal it prints out path as expected. So, which can find it.
UPDATE 2: I just created the bash script
#!/usr/bin/env bash
GP=`/usr/bin/which git`
PWD=`pwd`
echo "PATH IS: ${GP}"
echo "PWD IS: ${PWD}"
and output is
PATH IS:
PWD IS: /Users/user/tmp

所做的只是迭代 $PATH 中的目录，检查文件是否在那里。只需编写一个小方法即可完成同样的操作。
All which does is iterate over the directories in $PATH, checking to see if the file is there. Just write a small method to do likewise.
