一张假钞的真实世界

大道至简

如果使用开发分支代码如master分支）编译安装，需要自己编译语言文件。例如Hue安装目录为“/opt/hue”，则安装后执行以下命令：

1
2
$ cd /opt/hue
$ make locales

如果需要则重启Hue即可。是否需要重启我没有验证：）

错误原因：根据错误信息可以看到是“/usr/lib/python3/dist-packages/urllib3”这个包的问题。正确的应该是引用“build/env/lib/python3.7/site-packages/”下的包。查看”/usr/lib/python3/dist-packages/urllib3”下的包信息，发现包版本比较低。

$ python3 git.py 
Traceback (most recent call last):
  File "git.py", line 1, in <module>

  File "/home/a/git.py", line 1, in <module>
    from git import Repo
ImportError: cannot import name 'Repo' from 'git' (/home/a/git.py)

这种错误基本都是因为Python脚本的名称与模块的名称重复导致的。像我这个例子中就是因为git.py与GitPython模块中的文件名一样导致的。

本次问题解决纯属蒙对了，原理不清楚。

当我从一台CentOS 7.3的服务器通过ssh登录另外一台CentOS 6.8的服务器时出现以下错误信息：

今天在使用lftp的sftp时候一直处于connecting状态，并且没有其他提示信息。状态如下图所示：
lftp sftp

导致这个问题的原因是，在sftp第一次连接服务器的时候需要接收服务端服务器的fingerprint，这个过程需要用户通过输入进行确认，如下图所示。但是这些提示信息被lftp掩盖了，所以connecting状态其实是sftp一直在等待用户的输入。解决方法是先在命令行使用sftp连接一次服务器，然后再使用lftp。

Are you sure you want to continue connecting
