Julia spawn 'source' 导致没有这样的文件或目录

Question

Julia 的run函数似乎难以运行source。奇怪的是，如果我在 shell 中运行完全相同的命令，它就没有问题。

有没有办法从 Julia 以编程方式运行命令？

julia> cmd = "/home/me/tensorflow/bin/activate"
"/home/me/tensorflow/bin/activate"

julia> run(`ls $cmd`)
/home/me/tensorflow/bin/activate

julia> run(`source $cmd`)
ERROR: could not spawn `source /home/me/tensorflow/bin/activate`: no such file or directory (ENOENT)

shell> source /home/me/tensorflow/bin/activate

Answer 1

source 是内置命令

试试这样：

run(`zsh -c "source $cmd"`)

run(`bash -c source $cmd`)

视窗：

run(`cmd /c 'echo xxx'`)
