Question

nosetests抛出一个ImportError，尽管我认为这是一个正确配置的virtualenv。

======================================================================
ERROR: Failure: ImportError (No module named click)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/nose/loader.py", line 414, in loadTestsFromName
    addr.filename, addr.module)
  File "/usr/local/lib/python2.7/dist-packages/nose/importer.py", line 47, in importFromPath
    return self.importFromDir(dir_path, fqname)
  File "/usr/local/lib/python2.7/dist-packages/nose/importer.py", line 94, in importFromDir
    mod = load_module(part_fqname, fh, filename, desc)
  File "/home/kmaxwell/src/flail/tests/test.py", line 1, in <module>
    import flail
  File "/home/kmaxwell/src/flail/flail.py", line 14, in <module>
    import click
ImportError: No module named click

我正在使用setuptools，因此setup.py指定了

install_requires=[
    'click',
],

当我在virtualenv中安装pip install -e .时，我看到依赖安装正确。我还在virtualenv中安装了鼻子。

我需要配置什么才能让nosetests正确看到导入的包？

我今天想点击使用nosetests时遇到同样的错误。但我没有使用virtualenv。

这是我的解决方案，希望它对您有用：

错误

> nosetests test2.py

首先找到您的python和nosetests路径

> which python
/usr/local/bin/python

> which nosetests
/usr/local/bin/nosetests

确保为click
安装了/usr/local/bin/python
```
> /usr/local/bin/python -c 'import click'
```

检查/usr/local/bin/nosetests的第一行，它显示脚本正在运行时/usr/bin/python不正确。

> head -1 /usr/local/bin/nosetests
#!/usr/bin/python

> /usr/bin/python -c 'import click'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named click

将/usr/local/bin/nosetests的第一行修改为/usr/local/bin/python
```
> head -1 /usr/local/bin/nosetests
#!/usr/local/bin/python
```

现在我可以成功运行nosetests

> nosetests test2.py

OK

nosetests产生ImportError
