Question

几个月前，Matplotlib工作正常。但现在我不断收到错误：

ImportError: No module named matplotlib

我再次使用pip安装了matplotlib。它没有用。我用easyinstall。还是行不通。

pip安装提供

Requirement already satisfied (use --upgrade to upgrade): matplotlib in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib-1.5.0-py2.7-macosx-10.6-intel.egg
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from matplotlib)
Requirement already satisfied (use --upgrade to upgrade): python-dateutil in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/python_dateutil-2.4.2-py2.7.egg (from matplotlib)

Requirement already satisfied (use --upgrade to upgrade): six>=1.5 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/six-1.10.0-py2.7.egg (from python-dateutil->matplotlib)

然后我用了

sudo -E pip install matplotlib --upgrade

之后我得到了

The directory '/Users/ruskin/Library/Logs/pip' or its parent directory is not owned by the current user and the debug log has been disabled.        Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
The directory '/Users/ruskin/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled.   Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
You are using pip version 6.1.1, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

它继续升级matplotlib但最终我得到了

Answer 1

在OS X上，不要以root身份安装python模块，这是永无止境的快速配方。

使用--user的{{1}}参数，以便仅为当前用户安装模块，例如：

pip

另外，请确保您使用的是正确的python解释器，因为它常常会让pip感到困惑并在某个位置安装模块而不是python PATH（sys.path）中包含的模块。

ImportError：没有名为matplotlib的模块
