Question

我正在尝试在Google colab上永久安装库。所以我先运行这段代码：

import os, sys
from google.colab import drive
drive.mount('/content/drive', force_remount = True)

my_path = '/content/notebooks'
os.symlink('/content/drive/My Drive/Colab Notebooks/my_env', my_path)
sys.path.insert(0, my_path)

上面的代码没有错误。

但是，当我运行下面的代码时，出现了错误：

!pip install --target=$my_path jdc

During handling of the above exception, another exception occurred:

有没有办法解决这个问题？

Answer 1

%cd "/path/to/your/directory"

然后使用```pip``安装

pip install jdc
