Question

(centos6.6) 在更新python2.7.3之前，是python 2.6.6。运行pybot --version时，出现如下错误。

我要安装python 2.7.3和robot framework 2.7.6以及paramiko-1.7.4和pycrypto-2.6的测试环境

[root@localhost robotframework-2.7.6]# pybot --version
Traceback (most recent call last):

Answer 1

原因可能是以下任何一种:

1. Python 文件(至少一个)丢失了格式。 Python容易出现格式错误
2. 至少有一个安装(python、Robo)没有管理权限。
3. 环境变量(PATH、CLASSPATH、PYTHON PATH)设置不当。
4. python --version 打印什么？如果这会引发错误，则表明安装存在问题。
