Python 我无法使用pip安装plotly和geopandas软件包，我该怎么办？

我曾尝试以管理员身份在windows CMD中使用pip进行plotly安装，但始终出现以下错误：

$pip install plotly
Collecting plotly

我有python 3.7和windows 10。我还有自19年6月14日起的最新版本的pip和anaconda，如果有必要的话。

请提供一些更具体的信息。系统、python版本等仅在conda上试用？ 试试mb：

或

在conda上，这很有可能奏效：

conda install -c plotly plotly

我改了我的问题，请帮忙！我仍然没有得到关于我上面提到的命令的信息。。。你检查过了吗？如果是，发生了什么？带有conda ofcif的命令仍然无效-请尝试禁用防病毒，或任何可以阻止pip连接的命令。这似乎是在Windows上。使用sudo不适用。此答案可以/应该删除。我的答案在编辑问题之前发布，没有关于系统和环境的信息。仔细阅读。你的评论应该被删除，主持人先生在一个新的虚拟环境中尝试了相同的命令pip-install-plotly，没有问题。Windows 10、Python 3.7 Anaconda

sudo pip3 install plotly

conda install -c plotly plotly
