最近在Ubuntu14.04使用pip3安装软件包的时候出现了如下错误:TypeError: call() missing 1 required positional argument: ‘name’，具体报错信息如下：
ziven@ziven-ubuntu-laptop~pip3 install --user cheat

网上搜索了一下类似的问题，发现主要原因是:pyparsing的版本过低。
所以解决方法就是升级本地的pyparsing的版本到>=2.0.2.
所以在我本地我做了如下升级:
pip3 install --user --upgrade pyparsing
之后再执行之前的安装就正常了:
ziven@ziven-ubuntu-laptop~pip3 install --user cheat
