Question

只需从julialang.org安装Julia 1.0.0
请执行以下操作：

using Pkg

Pkg.add（“ PyPlot”）使用PyPlot

。。。得到这个错误： pyimport找不到Python软件包matplotlib。通常，这意味着您没有在PyCall使用的Python版本中安装matplotlib。

我已经安装了蟒蛇。

ERROR: InitError: PyError (PyImport_ImportModule

The Python package matplotlib could not be found by pyimport. Usually this means
that you did not install matplotlib in the Python version being used by PyCall.

Answer 1

这是否有帮助（将正确的路径设置为anaconda python二进制文件）？

ENV["PYTHON"] = "c:\\full\\path\\to\\anaconda\\bin\\python"
using Pkg
Pkg.build("PyCall")
using PyPlot

“使用PyPlot”导致Windows 10上的Julia 1.0.0错误：“ pyimport找不到Python软件包matplotlib。”
