无法运行ride.py:pkg_resources.DistributionNotFound:'robotframework-ride == 2.0a1

标签: python python-2.7 robotframework

我使用Mac,并且拥有python2.7.10,wxpython 3.0.2.0_1。坦率地说,它曾经可以工作,但是在我尝试“简单安装python3 && cp / usr / local / bin / python3 / usr / local / bin / python”之后。我无法运行ride.py并出现以下错误。

尽管我尝试回到当前的python2.7.10(而不是python3.x)

错误仍然如下。可以在这里建议我吗。

安装RIDE后(对于Robot Framework本身很可能是这样),这是针对python2完成的。安装python3将复制所有已安装的软件包-就操作系统和Python安装而言,这是两个单独的程序。
这就是您在python3中看到错误的原因。

关于为什么它现在在python2中不存在-我自己不确定;当您将python3二进制文件复制到python1二进制文件时,可能会使环境有些混乱。这通常是通过符号链接完成的,而不是二进制副本。您是为python做的,但是例如pip最有可能仍指向python2。

我要做的是尝试在python2中卸载robotframework和RIDE,然后在python2和python3解释器中pip install进行卸载。
