在`virtualenv`中使用'sudo'

I am working on a virtual environment: sk, which I made this way:

$ mkvirtualenv sk -p python3

I use workon sk to activate this environment and work in it. When I try to run some functionality of the perf utility in it, it asks for permission; it advises me to use sudo. On doing so, the essence of the environment gets lost as it doesn't detect any packages that I installed in it (e.g. pandas).

I have already gone through the similar article on this site as here, which suggests using the command

sudo ./AwesomeProject/bin/python <script>

where virtualenv is ./AwesomeProject. I tried it and found the Python instance within my virtual environments to be as .virtualenvs/sk/bin/python3. I run the instance as:

$.virtualenvs/sk/bin/python3 main.py

I get bash: .virtualenvs/sk/bin/python3: No such file or directory

(main.py is the python script I intend to run)

为什么用sudo会遇到此错误,我该如何克服呢?
