安装“sudo pip install -V protobuf==3.0.0a2”时出错

当我想安装protobuf时，我输入了命令：pip install -V protobuf==3.0.0a2，然后我收到以下结果：

Traceback (most recent call last):
File "/usr/local/bin/pip", line 9, in <module>

    from pip._vendor.pkg_resources import RequirementParseError
 ImportError: cannot import name RequirementParseError

有人知道如何解决吗？

你做错了。

  1. pip从......中去除在/usr/本地/bin
  2. pip从官方存储库安装（ sudo apt-get install python-pip）
  3. 然后使用以下方式安装 protobufsudo pip install -V protobuf==3.0.0a2

采取这些措施后，我protobuf 3.0.0a2安装到/usr/local/lib/python2.7/dist-packages。

请记住规则：如果你需要某些软件，请尝试找到它的包然后使用 apt-get 安装。它不像 Windows 那样有 EXE、MSI 和 MSP。从第三方软件包安装软件或从源代码编译软件会导致系统混乱，并使管理和使用更加困难。
