问题描述
所以我刚才尝试安装pySDL2，但是我不断收到错误消息:
So I tried to install pySDL2 just now, but I keep getting an error stating:
No module named 'sdl2.util'
我已经按照网站上的指示进行操作，所以我不知道为什么它不起作用.而且我没有看到其他人问这个问题.
I've followed the directions from the website, so I have no idea why this is not working. And I don't see anyone else asking this.
1: 我从BitBucket下载了"PySDL2-0.9.2.zip".
2: 我解压缩了文件夹并将其内容移出.
3: 我转到命令行，然后导航到包含setup.py
4: 我输入了(按照说明): python setup.py install
5: 该安装似乎运行良好，一旦将命令行返回给我，我便将其关闭.
6: 定位到示例文件夹，并尝试运行示例:
6: Navigated to the Examples folder, and tried to run an example:
然后我尝试导入sdl2，这导致了相同的错误.谁能告诉我为什么我会收到这些错误?还是我做错了什么?我不知道还有什么可以提供的信息.我实际上只遵循了提供的几个步骤，由于某种原因，我似乎无法从python访问SDL2.
I then tried importing sdl2, which resulted in the same error. Can anyone tell me why I am getting these errors? Or what I may have done wrong? I don't know what else to provide as information. I really only followed the couple steps provided, and for some reason I can't seem to access SDL2 from python . .
[更新]
因此，现在已消除了sdl2.util错误.我已将SDL2所需的DLL安装到Python33的DLLs文件夹中.然后，我尝试将DLL的环境变量设置为其位置. (这样，我就不会再遇到有关缺少的库等的错误).但是，这实际上并不能解决问题.该教程明确指出，应从命令行运行此命令以解决我的问题:
So the sdl2.util error has now been removed. I have installed the required DLL for SDL2 into the Python33's DLLs Folder. I then attempted to set the environment variable for the DLL to it's location. (So that I would stop getting error's concerning a missing library, ect). This doesn't actually fix the problem though. The tutorial clearly states that this command should be run from the command line in order to solve my issue:
然后我将其修改为指向DLL文件的位置:
I then modified this to point to the location of the DLL file:
好吧?没有.由于某种原因，这是行不通的.每次我想运行一个示例时，都需要像这样连续设置环境变量:
All good right? Nope. For some reason, this just doesn't work. Every time I want to run an example, I need to continuously set the environment variable as such:
os.environ["PYSDL2_DLL_PATH"] = "C:\\Python33\DLLs"
如果我不包括此内容，则会出现以下错误:
If I don't include this, I get the following error:
RuntimeError: could not find any library for SDL2 (PYSDL2_DLL_PATH: unset)
似乎没有设置我的环境变量，但是为什么我不知道这种情况.我尝试设置几次，然后重新启动一次.但这仍然存在.如果有人可以协助，那就太好了.
It would appear that my environment variable is not set, but why this is the case I don't know. I have tried setting it several times and restarted once. Yet this persists. If anyone can assist it would be great.
推荐答案
使用以下参数为Windows创建环境变量:
Creating an Environment Variable for windows with the following parameters:
变量名称: PYSDL2_DLL_PATH
Variable Name: PYSDL2_DLL_PATH
变量值: PATH_TO_THE_DLL_FILE_LOCATION
Variable Value: PATH_TO_THE_DLL_FILE_LOCATION
解决了该问题.
使用Windows set命令显然只是临时的.
Using the Windows set command is apparently only temporary.
