由于出现错误“ pkg_resources.DistributionNotFound，在Ubuntu 19.10上无法运行GNS3的问题：找不到'psutil == 5.6.7'分发”

如何解决由于出现错误“ pkg_resources.DistributionNotFound，在Ubuntu 19.10上无法运行GNS3的问题：找不到'psutil == 5.6.7'分发”

我在Ubuntu 19.10上安装了GNS3软件但这是行不通的。它从我运行的终端给出了此错误

Traceback (most recent call last):
  File "/ usr / local / bin / gns3",line 6,in <module>

    raise distributionNotFound (req,requirers)
pkg_resources.distributionNotFound: The 'psutil == 5.6.7' distribution was not found and is required by gns3-gui

我还使用psutil == 5.6.7命令安装了pip install psutil == 5.6.7。输出为：Requirement already satisfied: psutil == 5.6.7 in /usr/local/lib/python2.7/dist-packages (5.6.7)

您认为出了什么问题？

解决方法

已解决

我正在编写步骤，如果以后有人遇到此问题，他应该使用它...

首先，我使用命令pip3安装了apt install python3-pip

然后我用psutil命令安装了pip3 install psutil。

然后它写道gns3需要这些

gns3-server 2.2.15 requires aiofiles == 0.5.0,which is not installed.
gns3-server 2.2.15 requires aiohttp == 3.6.2,which is not installed.
gns3-server 2.2.15 requires aiohttp-cors == 0.7.0,which is not installed.
gns3-server 2.2.15 requires async-timeout == 3.0.1,which is not installed.
gns3-server 2.2.15 requires Jinja2> = 2.7.3,which is not installed.
gns3-server 2.2.15 requires jsonschema == 3.2.0,which is not installed.
gns3-gui 2.2.15 requires jsonschema == 3.2.0,which is not installed.
gns3-server 2.2.15 has requirement psutil == 5.6.7,but you'll have psutil 5.7.2 which is incompatible.
gns3-gui 2.2.15 has requirement psutil == 5.6.7,but you'll have psutil 5.7.2 which is incompatible.

然后我用pip3 install命令依次安装了它们，然后运行了gns3：）
