在ubuntu服务器上用anaconda升级beautifulsoup版本

如何解决在ubuntu服务器上用anaconda升级beautifulsoup版本

我有一个 anaconda 环境。我正在尝试将我的 beatifulsoup4 模块更新为更新版本，但我似乎卡在 4.6.3 上。我已经在我的 ubuntu 服务器上尝试了以下所有命令，但都没有成功。我收到下面的错误消息，或者在我运行命令后它只停留在 4.6.3。有没有人建议如何在 ubuntu 服务器上使用 anaconda 升级到至少 4.7.0 或更高版本的 beautifullsoup4？

conda install -c anaconda beautifulsoup4=4.7.0
conda update beautifulsoup4=4.7.0
conda install -c anaconda beautifulsoup4==4.7.0
conda install beautifulsoup4==4.7.0
conda upgrade beautifulsoup4==4.7.0
conda update beautifulsoup4==4.7.0
conda update beautifulsoup4=>4.7.0
conda update beautifulsoup4

我要了
