我已经减少了我遇到的问题。这是我的python脚本tmp.py
:
import numpy
print "Imported numpy!"
如果我直接在命令行调用python脚本
$ python tmp.py
它成功导入numpy并打印print语句。
以下是我的bash脚本test.sh
的内容:
#!/bin/bash
echo "PYTHONPATH:: $PYTHONPATH"
echo "PATH:: $PATH"
echo "LD_LIBRARY_PATH:: $LD_LIBRARY_PATH"
pyver=`which python`
echo "Using python version $pyver"
python tmp.py
如果我在命令行调用此脚本,
$ ./test.sh
我收到以下错误:
Traceback (most recent call last):

我已检查过echo $PYTHONPATH
,echo $PATH
,echo $LD_LIBRARY_PATH
和which python
的结果是否都返回相同,无论是在bash脚本中还是在命令行中调用。< / p>
我不知道发生了什么事!
答案 0 :(得分:3)
我有类似的问题。事实证明,在我的bash脚本中,我使用不同版本的Python运行Python脚本,而不是在命令行上运行(我的env是在Python 2.7上使用virtualenv设置的,但是我使用bash脚本中的Python3调用脚本)。
您的代码段中没有任何内容表明情况属实,但值得检查以确保Python版本匹配。
