为什么Python不运行我的bash代码？

Question

我正在尝试调试一些为测试集成提供的单元测试。

我确定这是最后一次工作，我在我的本地机器上测试过，但似乎已经改变 - 文件没有改变，所以我不知道自那时起有什么改变。

我已经删除了识别注释，并从原始单元测试中更改了一些名称，因为它是专有软件。

的语法错误是：

File "unitTests.sh", line 39 
    gLastFullPath=`python -c "import os; print os.path.realpath('${1}')"` 
       ^
SyntaxError: invalid syntax 

完整的脚本是在这里：

#!/bin/bash 

# If non-zero, then run in debug mode, outputting debug information 
debug=0 

# Set the following to 1 to force an error for testing purposes 
forceError=0 

separator="====================================================================================================" 

#------------------------------------------------------------------------------- 
# Convert the specified path to a full path and return it in the gLastFullPath 
# global variable. 
# 
# Input params: 
# $1 - Path to convert to full 
# 
# Output params: 
# $gLastFullPath - Set to the converted full path 
gLastFullPath="" 
getFullPath() 
{ 
    # Use Python (because it's easier than Bash) to convert the passed path to 
    # a full path. 
    gLastFullPath=`python -c "import os; print os.path.realpath('${1}')"` 
}

这一切正在在Python运行2.7

这是一个bash脚本，而不是一个Python脚本。使用./script_name.sh或bash script_name.sh而不是python script_name.sh运行它。
