我已经从here下载并运行了ez_setup.py。然后我跑easy_install -m matplotlib给了下面的文字墙，我不明白。

Because this distribution was installed --multi-version, before you can
import modules from this package in an application, you will need to
'import pkg_resources' and then use a 'require()' call similar to one of
these examples, in order to select the desired version:
pkg_resources.require("matplotlib") # latest installed version
pkg_resources.require("matplotlib==1.5.1") # this exact version
pkg_resources.require("matplotlib>=1.5.1") # this version or higher

如果我现在尝试导入matplotlib，我会

所以我尝试使用上面输出建议的pkg_resources，然后获取

我尝试通过pip和pip3安装它也不起作用。
答案 0 :(得分：1)
问题可能是由LC_CTYPE
$ locale
LANG="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_CTYPE="UTF-8" # !
LC_MESSAGES="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_ALL=
作为一种解决方法，在运行Python之前将LC_ALL设置为适当的语言环境：
$ export LC_ALL=en_GB.UTF-8
$ python -c "import matplotlib"
答案 1 :(得分：0)
这是一种更简单的方法：
C:\Python27\Scripts）pip install matplotlib 希望这有帮助！ （正如你所提到的，你曾试过pip，请告诉确切的错误，即使这不起作用。这对我有用。）
