将tk8.6和tcl8.6复制到C:\\Program Files\\Python37\\Lib下即可解决。
具体原因未知

找到原因

eclipse导入项目时出现小红叉，但项目内容没有报其他错误。

报错信息:Description Resource Path Location Type Target runtime Apache Tomcat v8.0 is not defined. ssh Unknown Faceted Project Problem

解决办法:

1，在Eclipse工程目录下的.settings文件夹里，打开org.eclipse.wst.common.project.facet.core.xml文件，其内容是：<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<runtime name="Apache Tomcat v6.0"/>
<fixed facet="jst.web"/>
<fixed facet="jst.java"/>
<installed facet="jst.java" version="5.0"/>
<installed facet="jst.web" version="2.4"/>
</faceted-project>
不要删了文件也不要全删除，要不还会有错误，删除中间几行，只留下下面三行就行
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
</faceted-project>

2，或者修改tomcat的版本也可以。
