python - nosetests 产生 ImportError

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

----------------------------------------------------------------------

我使用的是setuptools，所以setup.py指定

install_requires=[
    'click',
],

当我在我的 virtualenv 中使用 pip install -e . 安装时，我看到依赖项安装正确。我还在 virtualenv 中安装了 nose。

我需要配置什么才能使 nosetests 正确看到导入的包？

今天我想通过点击使用 nosetests 时遇到了同样的错误。但我没有使用 virtualenv。

这是我的解决方案，希望对你有用:

1. 运行 nosetests 时出错

   > nosetests test2.py
   E
   ======================================================================
   ERROR: Failure: ImportError (No module named click)
   ----------------------------------------------------------------------
   Traceback (most recent call last):
     File "/Library/Python/2.7/site-packages/nose/loader.py", line 414, in loadTestsFromName
       addr.filename, addr.module)
     File "/Library/Python/2.7/site-packages/nose/importer.py", line 47, in importFromPath
       return self.importFromDir(dir_path, fqname)
     File "/Library/Python/2.7/site-packages/nose/importer.py", line 94, in importFromDir

     File "/data/home/user00/tools/auto_open_server/test2.py", line 3, in <module>
       import click
   ImportError: No module named click

2. 首先找到您的 python 和 nosetests 路径

   > which python
   /usr/local/bin/python
   
   > which nosetests
   /usr/local/bin/nosetests
   

3. 确保为 /usr/local/bin/python 安装了 click

   > /usr/local/bin/python -c 'import click'
   

4. 检查/usr/local/bin/nosetests的第一行，它表明脚本正在运行 /usr/bin/python 这是不正确。

   > 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
   

5. 将/usr/local/bin/nosetests第一行修改为/usr/local/bin/python

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

6. 现在我可以成功运行nosetests

   > nosetests test2.py
