无法从命令行 运行 基于 Robot Framework 中的标记的测试用例
Unable to Run Testcases Based on Tag in Robot Framework form cmd line
今天，突然我的机器人Runner.py不工作了。基本上 Runner.py 包含 运行 我的基于标签的机器人测试用例的命令行命令。
每次 Runner.py 为 运行 时，将执行一个 requirements.txt 文件，其中的所有库将由 python 解释器安装。
cmd="pip install -r Requirements.txt --trusted-host files.pythonhosted.org --user"
os.system(cmd)
然后测试用例由 python 解释器 运行 使用：
cmd="robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
os.system(cmd)
报告生成使用：
cmd="python3 -m robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
os.system(cmd)
其中 RunNow 是我在测试用例中使用的标签，TestSuite 是我的文件夹，其中包含我的 .robot 测试文件。
直到昨天所有这些命令都运行良好，但今天它不起作用，我得到的第一个错误是

然后我尝试 pip freeze > file.txt 安装了所有库，通过命令卸载了所有库
cmd="pip uninstall -r file.txt"
os.system(cmd)
当我在命令提示符下运行 runner.py文件时，它首先卸载了file.txt中的所有库并安装了Requirements.txt中的所有库并结束了说
robot is not recognized as internal or external command robotframework, robotmetrics is not recognized as internal or external command robotframework
所以经过一些研究我更换了
cmd="robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
至
cmd="python3 -m robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
和
cmd="robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
至
cmd="python3 -m robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
现在，在进行此更改后，我没有收到机器人，或者 robotmetrics 未被识别为内部或外部命令 robotframework，但 **我的测试用例未根据标签拾取，实际上它只是执行安装所有库的命令在 Requirements.txt 并停止。
在 运行ning Runner.py 之后，我的命令提示符如下所示：

请帮忙解决这个问题...
要理解发生的事情并不容易。当你说：
Till Yesterday all this commands were working perfectly, but today it was not working, the first error I got is
unexpected error: valueerror: not enough values to unpack (expected 3, got 1) robot
您首先需要确定错误的来源。也许错误之前省略的行可以帮助做到这一点。
我在这种（奇怪的）安装方式和 运行 robot 中看到的一个问题是您没有为软件包设置特定版本。如果一个包的新版本导致错误，那么你可能就是现在的情况。
今天，突然我的机器人Runner.py不工作了。基本上 Runner.py 包含 运行 我的基于标签的机器人测试用例的命令行命令。 每次 Runner.py 为 运行 时，将执行一个 requirements.txt 文件，其中的所有库将由 python 解释器安装。
cmd="pip install -r Requirements.txt --trusted-host files.pythonhosted.org --user"
os.system(cmd)
然后测试用例由 python 解释器 运行 使用：
cmd="robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
os.system(cmd)
报告生成使用：
cmd="python3 -m robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
os.system(cmd)
其中 RunNow 是我在测试用例中使用的标签，TestSuite 是我的文件夹，其中包含我的 .robot 测试文件。
直到昨天所有这些命令都运行良好，但今天它不起作用，我得到的第一个错误是

cmd="pip uninstall -r file.txt"
os.system(cmd)
当我在命令提示符下运行 runner.py文件时，它首先卸载了file.txt中的所有库并安装了Requirements.txt中的所有库并结束了说
robot is not recognized as internal or external command robotframework, robotmetrics is not recognized as internal or external command robotframework
所以经过一些研究我更换了
cmd="robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
至
cmd="python3 -m robot -i RunNow -d ../Output/Execution_%s -P ../CustomLibrary/ --extension robot ../TestSuite "%(dts)
和
cmd="robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
至
cmd="python3 -m robotmetrics -R ExecutionMetrics -I ../Output/Execution_%s --logo ../../Resources/logo.png --ignorelib ['OperatingSystem'] --ignoretype ['for']" %(dts)
现在，在进行此更改后，我没有收到机器人，或者 robotmetrics 未被识别为内部或外部命令 robotframework，但 **我的测试用例未根据标签拾取，实际上它只是执行安装所有库的命令在 Requirements.txt 并停止。
在 运行ning Runner.py 之后，我的命令提示符如下所示：

请帮忙解决这个问题...
要理解发生的事情并不容易。当你说：
Till Yesterday all this commands were working perfectly, but today it was not working, the first error I got is
unexpected error: valueerror: not enough values to unpack (expected 3, got 1) robot
您首先需要确定错误的来源。也许错误之前省略的行可以帮助做到这一点。
我在这种（奇怪的）安装方式和 运行 robot 中看到的一个问题是您没有为软件包设置特定版本。如果一个包的新版本导致错误，那么你可能就是现在的情况。
