如何在网络服务器上导入自己的模块？
[英]How can I import my own modules on webserver?
问题描述
I am developing a website and want to put some files on the server. 
我正在开发一个网站，并希望将一些文件放在服务器上。 The problem is that I can only import python modules ( eg "import os"), but somewhy, can not import my own modules: 问题是我只能导入python模块（例如“ import os”），但是为什么不能导入我自己的模块：
test1.py: test1.py：
import test2
test2.py: test2.py：
print ("Content-type:text/html\n\n")
print ("<html>")
print ("<head>")
print ("<title>Error</title>")
print ("</head>")
print ("<body>")
print (" hello world 2")
print ("</body>")
print ("</html>")
If I click www.mywebsite.com/test2.py, then I recieve "hello world" on the screen. 如果单击www.mywebsite.com/test2.py，则在屏幕上会收到“ hello world”。 However, if I click www.mywebsite.com/test1.py, I get "500 internal server error." 但是，如果我单击www.mywebsite.com/test1.py，则会收到“ 500内部服务器错误”。 I found out that it is some problem with not being able to import my modules. 我发现无法导入模块存在一些问题。
ps since I am on a shared server, I can not changes sys path etc.... ps，因为我在共享服务器上，所以我无法更改sys path等。
Here is a trace I got in errors.log: 这是我在errors.log中遇到的痕迹：

In the last line, you can see that the server writes "ImportError: No module named test2" 在最后一行中，您可以看到服务器写入“ ImportError：No module named test2”
How can I fix it? 我该如何解决？

Modules should be in the Python path or in the same directory where the executable is. 模块应位于Python路径中或可执行文件所在的目录中。
Then you do like usually 那你平时喜欢
import test2
test2.some_function() # or whatever.

From your description, your program did not found your own module, because you did not give your module's path. 根据您的描述，您的程序未找到您自己的模块，因为您未提供模块的路径。 Now there are two methods to solve it: 现在有两种解决方法：
Assume your module's path is: /srv/modules/xxxx.py First you should import your module in your program: import xxxx 假设模块的路径是： /srv/modules/xxxx.py首先，您应该在程序中import xxxx模块： import xxxx
command line:Before you run your program with command line, give the path first.
命令行：在使用命令行运行程序之前，请先指定路径。 command: export PYTHONPATH=/srv/modules.Then run your program.命令： export PYTHONPATH=/srv/modules。然后运行程序。add two lines of codes in your program:
在程序中添加两行代码： import sys sys.path.append("/srv/modules")
Use any one way above, you should run your program success.I hope this can help you. 使用上面的任何一种方法，您都应该成功运行程序。希望对您有所帮助。
