python - 导入错误: cannot import name redirect_stderr

Question

我认为这在某种程度上与安装的Python有关，但我不知道如何修复它。

这就是我所拥有的:

$ python --version
Python 2.7.12

$ pyftsubset
Traceback (most recent call last):
  File "/usr/local/bin/pyftsubset", line 7, in <module>
    from fontTools.subset import main
  File "/usr/local/lib/python2.7/dist-packages/fontTools/__init__.py", line 1, in <module>
    from fontTools.misc.py23 import *
  File "/usr/local/lib/python2.7/dist-packages/fontTools/misc/__init__.py", line 3, in <module>
    from fontTools.misc.py23 import *
  File "/usr/local/lib/python2.7/dist-packages/fontTools/misc/py23.py", line 6, in <module>
    from contextlib import redirect_stderr, redirect_stdout
ImportError: cannot import name redirect_stderr

Answer 1

您需要卸载fontTools，然后安装py27它的分支。您使用的版本不向后兼容 Python 2.7
