由于错误" pkg_resources.DistributionNotFound: The 'psutil == 5.6.7' distribution was not found "，在 Ubu

Question

我在Ubuntu 19.10上安装了GNS3软件但它不起作用。它从我运行的终端给出了这个错误

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

pkg_resources.DistributionNotFound: The 'psutil == 5.6.7' distribution was not found and is required by gns3-gui

我还使用pip install psutil == 5.6.7命令安装了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)

你认为问题出在哪里？

已解决

我正在写一些步骤，如果有人以后遇到这个问题，他应该使用它。。。

首先，我用命令apt install python3-pip安装了pip3

然后我用pip3 install psutil命令安装了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命令按顺序安装了它们，然后运行gns3：(
