Question

我使用Activepython安装了rarfile库（我正在使用mac os和eclipse），虽然似乎已经正确安装了所有内容，但我仍然通过简单的提取测试继续收到此错误消息：

File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile.py", line 1843, in custom_popen
    raise RarExecError("Unrar not installed? (rarfile.UNRAR_TOOL=%r)" % UNRAR_TOOL)
rarfile.RarExecError: Unrar not installed? (rarfile.UNRAR_TOOL='unrar')

我检查了我的计算机上rarfile库的安装位置，并在Eclipse上的include文件中定义了库路径（Window - ＆gt; Preferences - ＆gt; Pydev - ＆gt; Interpreter - Python - ＆gt; System PYTHONPATH）：

/Bibliothèque/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile-2.6-py2.7.egg-info

/Bibliothèque/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile.py

/Bibliothèque/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile.pyc

/Bibliothèque/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile.pyo

我仍然收到此错误消息：

File "/Users/moi/Documents/workspace/Apprentissage/Dezipper/test_rarfile_2.py", line 3, in <module>
    ref.extractall('/Users/moi/Downloads/_zips/rars/')
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile.py", line 675, in extractall
    self._extract(fnlist, path, pwd)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile.py", line 1202, in _extract
    p = custom_popen(cmd)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/rarfile.py", line 1843, in custom_popen
    raise RarExecError("Unrar not installed? (rarfile.UNRAR_TOOL=%r)" % UNRAR_TOOL)
rarfile.RarExecError: Unrar not installed? (rarfile.UNRAR_TOOL='unrar')

对这个问题有什么看法？非常感谢。

好的，我解决了这个问题。除了在python中安装rarfile库之外，我还需要安装unrar库。在mac os x上，可以通过在终端中执行此操作：

cd /tmp
curl -o output.tar.gz http://www.rarlab.com/rar/rarosx-3.9.3.tar.gz
Untar the tar ball, enter:

tar -zxvf output.tar.gz

现在，rar被解压缩，我不再收到错误消息了。很高兴知道。
