python - 安装软件包 (conda) 会导致 ImportError : Library not loaded

Question

我通过conda安装了seaborn包:

~user: conda install seaborn

The following NEW packages will be INSTALLED:
seaborn:     0.8-py27_0      
The following packages will be UPDATED:
conda:       4.3.8-py27_0     --> 4.3.30-py27h407ed3a_0
matplotlib:  1.4.3-np19py27_2 --> 1.5.3-np111py27_1    
statsmodels: 0.6.1-np19py27_0 --> 0.8.0-np111py27_0  

它搞乱了我的 matplotlib 安装，现在当我运行 python 脚本时，它在导入 matplotlib 时引发错误:

ImportError: dlopen(/Users/.../anaconda/lib/python2.7/site-packages/matplotlib/_png.so, 2): Library not loaded: @rpath/libpng16.16.dylib
Referenced from: /Users/.../anaconda/lib/python2.7/site-packages/matplotlib/_png.so
Reason: Incompatible library version: _png.so requires version 39.0.0 or later, but libpng16.16.dylib provides version 34.0.0 

Answer 1

此错误可能是由旧版本的 conda 引起的。您需要先更新 conda，然后重试。

conda update conda
