Question

我在主目录中为python3创建了一个虚拟环境，我只能运行那些保存在主目录中的文件，如果我尝试运行存储在例如Desktop的文件，则会出现以下错误：

(py3) gopi@gopi-inspiron:~/Desktop$ python detector_modulation_01.py
PyCBC.libutils: pkg-config call failed, setting NO_PKGCONFIG=1
Traceback (most recent call last):
  File "/home/gopi/py3/lib/python3.6/site-packages/numpy/compat/py3k.py", line 30, in <module>
    import pickle5 as pickle
ModuleNotFoundError: No module named 'pickle5'

During handling of the above exception, another exception occurred:

我也不能在在Desktop打开的Python shell上导入numpy或PyCBC。这个virtualenv的主要用途是使用Python3运行PyCBC代码。

这是因为环境的根位于您创建的目录中，所以它对目录的层次结构视而不见（例如，如果您的home目录路径为C:\Username\Home，并且您创建了虚拟环境-无法看到C:\Username目录中的文件），这是您首先创建虚拟环境的原因之一，因此它不会与其他环境中的文件冲突目录。

因此要解决此问题，您基本上有两个选择：

在计划使用的文件的顶层结构目录中创建环境。
将文件移动到当前环境的根目录所在的目录。

干杯。

Python3虚拟环境无法保存与虚拟环境位置不同的文件
