我试图在一个非常基本的Python脚本上运行,只是为了测试它。不幸的是,我遇到了一个我无法正确理解的错误。
$ nuitka-run dice_test.py
Nuitka:WARNING:The version '3.6' is not currently supported. Expect problems.

为什么python 2和python 3中的代码输出是不同的?
class A:
def m(self):
print("m of A called")
class B(A):
pass
class C(A):
def m(self):
print("m of C called")
class D(B,C):
pass
x = D()
x.m()
实际产出:
$ python diamond1.py //python 2 used for the code
m of A call
我正在尝试为python2.7 ( mint上的默认设置)编译pyque-val-138.0库:
因此,当通过./configure运行配置脚本时,我会看到有关python解释器版本的错误:
...snip...
checking for a Python interpreter with version =2.3... done
checking for a Python interpreter with version =2.4... done
checking for a Python interpreter with version =2.5... done
我使用这个python脚本:
芘2.6和2.7
for i in xrange(1000000):print i
python3.3
for i in range(1000000):print(i)
结果:
python 2.7
real 1m15.973s
user 0m3.392s
sys 0m6.384s
Python2.6
real 1m15.860s
user 0m3.064s
sys 0m6.296s
使用python3.3,我对脚本进行了多次测试,并获得了运行的这种差异。
python 3.3
real 1m34.235s
user 0m10.

我正在创建Django应用程序,并停留在虚拟安装。我见过并试图跟随它,但每次我尝试一些东西时,它都会导致这种情况。为什么不能用python 3来安装,但这可以用virtualenv venv,但是它可以安装python2。我该怎么办?
