在virtualenv中找不到Python模块

我已尝试安装python模块：

virtualenv .
source bin/activate
pip install utmp

它似乎安装在：

(wtmp)chris@chris-nb:~/computer/wtmp$ find -iname utmp
./bin/utmp
./lib/python2.7/site-packages/utmp

但是Python说没有找到它：

(wtmp)chris@chris-nb:~/computer/wtmp$ ./wtmp.py
Traceback (most recent call last):
  File "./wtmp.py", line 3, in <module>
    import utmp
ImportError: No module named utmp

（wtmp）chris@chris-注意：~/computer/wtmp$。/wtmp.py
回溯（最近一次呼叫最后一次）：
文件“/wtmp.py”，第3行，在
导入utmp
ImportError:没有名为utmp的模块

这是模块问题吗？我做错什么了吗

如果重要的话，操作系统是Ubuntu

以下是重新安装日志：

搜索pyflakes>=0.8.1，您可以通过调用
pip list
或
pip show utmp
来检查它是否安装在您的virualenv中

如果没有，请尝试重新安装：

pip安装--升级--无deps--强制重新安装utmp

并用错误日志扩展您的问题

还要验证，因为它可能不会指向您的virtualenv。
刚刚遇到了相同的问题。我通过使用
哪个python
找到了问题所在。它告诉我，实际上我有一个别名，它指向一个不同于当前
virtualenv
中的python可执行文件。显然，别名比通过
source
设置的路径更重要。它似乎已安装：（wtmp）chris@chris-注意：~/computer/wtmp$pip list argparse（1.2.1）enum（0.4.4）pip（1.5.4）setuptools（2.2）utmp（0.4）wsgiref（0.1.2）您是否尝试过重新安装它：
pip安装--升级--无deps--强制重新安装utmp
？我已在上面添加了重新安装日志。您是否可以尝试启动python解释器并键入
import utmp
。如果这样做有效，问题就出在
wtmp.py
脚本中。检查，因为它可能不会指向您的venv。谢谢！我用错了Shebang线！自从我上次使用python和virtualenv已经有一段时间了。是的，别名优先。为什么这与这个问题有关？这是相关的，因为这可能是为什么在virtualenv中找不到Python模块的原因之一。如果有人早点把它贴在这里，我会更快地解决我的问题，因此我想我会在这里添加我的解决方案作为提示。
