Python virtualenv不指向本地可执行文件

我注意到安装在本地机器上的virtualenv的奇怪行为。这就是我一直在做的：

tomasz@laptop:~/Development/Python$ virtualenv nac-env
New python executable in nac-env/bin/python
Installing Setuptools...................................................................................................................................................................................................................................done.
Installing Pip.....................................................................................................................................................................................................................................................................................................................................done.
tomasz@laptop:~/Development/Python$ cd nac-env
tomasz@laptop:~/Development/Python/nac-env$ source ./bin/activate
(nac-env)tomasz@laptop:~/Development/Python/nac-env$ which python
/usr/bin/python
(nac-env)tomasz@laptop:~/Development/Python/nac-env$ which pip
/usr/bin/pip
(nac-env)tomasz@laptop:~/Development/Python/nac-env$ which easy_install
/usr/local/bin/easy_install
(nac-env)tomasz@laptop:~/Development/Python/nac-env$ echo $PYTHONPATH
/usr/lib/python2.7/site-packages:/usr/lib/python2.7/dist-packages
(nac-env)tomasz@laptop:~/Development/Python/nac-env$ deactivate
tomasz@laptop:~/Development/Python/nac-env$ 

正如nettuts屏幕广播（，6:55），

python

，

pip

和

easy\u install

可执行文件应该指向虚拟环境中的文件，而不是指向

/usr/bin/…

之类的东西。如果

$PYTHONPATH

系统变量设置不正确，我认为我的安装没有按预期工作。。。有人知道出了什么问题吗

---

PS我不久前在本地机器上安装了virtualenv。很可能是通过pip或类似的方式输入的。

好吧，我确信我的这种行为是不正常的。我已经卸载了现有的

virtualenv

，并从

pip

重新安装了它，现在一切正常：

tomasz@laptop:~/Development/Python/foo$ source bin/activate
(foo)tomasz@laptop:~/Development/Python/foo$ which python
/home/tomasz/Development/Python/foo/bin/python
(foo)tomasz@laptop:~/Development/Python/foo$ which pip
/home/tomasz/Development/Python/foo/bin/pip
(foo)tomasz@laptop:~/Development/Python/foo$ which easy_install
/home/tomasz/Development/Python/foo/bin/easy_install
(foo)tomasz@laptop:~/Development/Python/foo$ echo $PYTHONPATH
/usr/lib/python2.7/site-packages:/usr/lib/python2.7/dist-packages

---

这件事发生在我身上。您是否更改了项目路径

---

当我第一次创建虚拟环境时，我使用了

~/src/my\u project/venv

，但后来将其更改为

~/projects/my\u project/venv

。当我运行激活脚本时，它使用的是旧路径。为了解决这个问题，我用新路径替换了激活目录中的所有脚本，

python

，

pip

等现在都是从虚拟环境中获得的。

您是如何安装VirtualEnvironment的？这不是正常的行为。也许，用系统的python或pip重新安装？@VooDooNOFX不记得我是怎么做的，但你的建议是对的。重新安装后，一切正常，谢谢！
