Julia spawn'ource'导致没有这样的文件或目录

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。

有没有办法以编程方式从Julia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

source是内置命令

尝试这样:

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

run(`bash -c source $cmd`)

窗口:

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