如何解决点安装火车失败
在虚拟环境中运行@ExtendWith(MockitoExtension.class)
class MaskingPatternLayoutTest {
@Mock
ILoggingEvent event;
@Test
void doLayouttest(){
String patternsproperty = "sensitive string";
String mask = "*";
String logMessage = "message";
// On call of following line in MaskingPatternLayout class,I want to stub the logMessage string
// String logMessage = super.doLayout(event);
// I have tried following approach but Couldn't stub the logMessage string
// ******* Approach - 1 ********
final MaskingPatternLayout maskingPatternLayout = Mockito.spy(new MaskingPatternLayout());
Mockito.doReturn("mocked parent").when((PatternLayout)maskingPatternLayout).doLayout(event);
// with the above approach MaskingPatternLayout class doLayout() method will not execute,instead
// it returns logMessage string but I wanted to stub on calling "super.doLayout(event)"
// ******* Approach - 2 ********
//when(layout.doLayout(event)).thenReturn(logMessage);
// Above statement will not work because of calling "doLayout(event)" using super keyword
// ******* Approach - 3 ********
// PatternLayout super class provides another protected method "writeLoopOnConverters(event)"
// which provide same return value of "super.doLayout(event)" So,I have tried as fallows
// First I have done spy on "PatternLayout layout = spy(PatternLayout.class);" and added the
// following statement.
Mockito.doReturn("mocked parent").when((PatternLayout)maskingPatternLayout).doLayout(event);
// But above line will skip calling "doLayout(ILoggingEvent event)" method of
// "MaskingPatternLayout" class
String maskedLog = maskingPatternLayout.doLayout(event);
assertNotNull(maskedLog );
}
}
后
我得到了
pip install trains我知道I am not supposed to run under sudo when using a venv，所以我不太了解这个问题
例如运行 ERROR: Command errored out with exit status 1:

确实可以。
Python 3.8
如何安装火车？
编辑：
运行pip install pandas或pip install trains --user给出
pip install --user trains解决方法
您有两个选择：
-
创建一个虚拟环境并在其中安装软件包（首选）
-
通过传递--user标志，将软件包安装在用户主目录中
pip install --user
问题是venv的权限问题。 另一个问题是火车需要一些软件包，而这些软件包在Python3.8上还没有带轮子，因此我不得不将Python降级到3.7
该venv是使用Pycharm创建的，由于某种原因，它是使用低权限创建的。
可能有一种提高权限的方法，但是我只是删除了它，并使用命令行创建了另一个方法，
python -m virtualenv --python=/usr/bin/python3.7 venv
现在pip install trains工作了。
非常烦人。
