Multilpe python版本和解释器 [英] Multilpe python versions and interpreters

问题描述

我正在尝试在我的 Windows 7 机器上设置 python 2.7.6(首先安装了 python 3.3.3).在设置项目解释器中添加项目解释器后选择项目解释器时，出现此错误

I am trying to setup python 2.7.6 on my windows 7 machine (python 3.3.3 was installed first). When selecting the project interpreter after adding it in settings-project interpreter, I get this error

文件C:Python33Libsite.py"，第 173 行文件=sys.stderr) ^ SyntaxError: invalid syntax

File "C:Python33Libsite.py", line 173 file=sys.stderr) ^ SyntaxError: invalid syntax

最初在设置页面中添加python 2.7解释器时(与上面添加虚拟环境相比)，它给出了这个错误消息

When initially adding the python 2.7 interpreter in the settings page (as compared to adding the virtual environment above), it gives this error message

无法在 C: 设置 python SDK: .... .SDK 似乎无效.

Cannot setup python SDK at C: .... . The SDK seems invalid.

在添加基于该解释器的任何虚拟环境时，我也会遇到类似的错误.

I also get a similar error when adding any virtual env based on that interpreter.

我已经在路径框中添加了 python27 路径，如图所示，但它似乎正在查看 Windows 中设置的路径.如果我必须改变这一点，那是否会破坏能够选择多个口译员的意义?

I've added the python27 paths in the Paths box as in the picture, but it seems to be looking at the path set in windows. If I have to change that, doesnt that defeat the point of being able to select multiple interpreters?

任何帮助将不胜感激.

推荐答案

我犯了一个非常愚蠢的错误:我使用的是 PYTHONPATH 而不是 PATH.我将 PYTHON33 和 PYTHON27 都添加到了我的 PATH 中，并且成功了.

I made a really silly mistake: I was messing with PYTHONPATH instead of PATH. I added both PYTHON33 and PYTHON27 to my PATH and it worked.
