无法安装龙卷风

Question

我正在设置 tensorflow，我得到了这个输出：

ERROR: matplotlib 1.3.1 requires nose, which is not installed.

原来如此

sudo easy_install tornado

我得到了输出：

earching for tornado
Reading https://pypi.python.org/simple/tornado/
Download error on https://pypi.python.org/simple/tornado/: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) -- Some packages may not be found!
Couldn't find index page for 'tornado' (maybe misspelled?)
Scanning index of all packages (this may take a while)

No local packages or download links found for tornado

我该怎么办？ 谢谢 法国

错误：matplotlib 1.3.1 需要nose，未安装。

您似乎在代理或防火墙后面运行命令。如果是这种情况，那么需要设置相应的环境变量：

set http_proxy="username:password@host:port"
set https_proxy="username:password@host:port"

否则，您可以通过运行使用pip 安装tornado（如果您不在代理后面，则忽略--proxy）：

pip --proxy http://user:password@proxy-host:port install tornado

编辑：我建议运行

sudo -H pip install --ignore-installed matplotlib

为了安装所需的软件包并忽略当前版本。
