[英]Installing matplotlib inside a virtualenv using pip on a Mac
The command suggested* to install matplotlib for python was: 建议*为python安装matplotlib的命令是:
pip install -U git+git://github.com/matplotlib/matplotlib.git
after choosing a virtualenv and then running that command, I received what looked like positive results until: 选择virtualenv然后运行该命令之后,我收到了看起来像是肯定的结果,直到:
* The following required packages can not be built:
* freetype
Yet I have freetype
or freetype2
all over my system - even in the Anaconda install. 但是我在整个系统上都有
freetype
或freetype2
即使在Anaconda安装中也是如此。 I tried adding all sorts of paths to my $PATH
like: 我尝试将各种路径添加到
$PATH
例如:
/anaconda/include/freetype2/freetype
/anaconda/include/freetype2/
/anaconda/include/
//anaconda/include/freetype2/freetype
And nothing seems to work, at least in terms of calling which freetype
. 而且似乎没有任何作用,至少就调用
which freetype
。
Is there another way to show the system that I have freetype? 有没有其他方法可以向系统显示我具有自由类型? Am I just misusing
$PATH
? 我只是在滥用
$PATH
吗?

Cleaning up...
Command python setup.py egg_info failed with error code 1 in /var/folders/pl/9hfxwbf17knbpqpmdd4tq5j00000gn/T/pip-ZGwnWX-build
Storing debug log for failure in /Users/rpanos/.pip/pip.log
Maybe this is not what you want at all, but can you use conda
to make your environment instead? 也许这根本不是您想要的,但是您可以使用
conda
来创建环境吗? Eg conda create -n myenv anaconda
? 例如,
conda create -n myenv anaconda
吗? That would already have matplotlib in it. 那已经有matplotlib了。 You can also customize exactly what goes in.
您还可以完全自定义输入内容。
I had the same issue. 我遇到过同样的问题。 The way it worked for me is the following:
它为我工作的方式如下:
sudo apt-get -y build-dep matplotlib # then enter you root password
virtualenv -p python2.7 ~/venv
source ~/venv/bin/activate
The key being the first step where system wide matplotlib
dependencies are installed. 关键是安装系统范围的
matplotlib
依赖项的第一步。 Source of this here . 这里的来源。
