如何在 NAO 机器人中安装 pip 以安装外部包

Question

我已经编写了一些代码并想在 NAO 机器人上运行它，但不幸的是，我在代码中使用了一些包，如 pygame 和 boto3，所以现在要在 NAO 上运行此代码，我必须在 NAO 机器人上安装这些包，有人可以解释一下这个过程吗？

我尝试使用 ssh nao@ip 在 NAO 上运行 get-pip.py 文件，但无法安装 我一直在尝试将包文件复制到 NAO，但它也没有解决问题。 我关注了https://community.ald.softbankrobotics.com/ja/node/1506论坛，也没有解决

下面是我运行 get-pip.py 文件时的控制台输出

另外，我尝试更新系统时间，但这也没有解决问题。输出和以前一样：

root@nao [err 127] nao # ntpdate

root@nao [0] nao # ntpdate
11 Jul 10:51:42 ntpdate[9024]: no servers can be used, exiting

我还尝试使用sudo python setup.py install 安装没有 pip 的软件包 但在这种情况下，它会显示以下错误：

error: could not create '/usr/lib/python2.7/site-packages/awscli-1.16.196-py2.7.egg': No space left on device

Answer 1

你有一个：

SystemTimeWarning：系统时间已过时（2017-06-30 之前）。这 可能会导致 SSL 验证错误

修复您的系统时间，否则 ssl 验证将失败。

它可能与胡椒类似，按照说明here

你也得到了

SNIMissingWarning：已发出 HTTPS 请求，但 SNI（服务器 Name Indication) 对 TLS 的扩展在此平台上不可用。 这可能会导致服务器提供不正确的 TLS 证书， 这可能导致验证失败。您可以升级到更新的 版本的 Python 来解决这个问题。有关详细信息，请参阅 https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings

要修复它，您需要安装 requests[security] 包

您也可以按照here 的描述安装没有 pip 的软件包
