我將帶有 /venv 的 Django 項目（mysite）重新定位到另一臺計算機。在第一臺電腦上它運行良好。'dotenv' 模塊安裝在哪里。在 PyCharm 中，我將項目解釋器設置為：Python 3.7 (mysite) C:\Users\User\mysite\venv\Scripts\python.exe但是新計算機中的“python manage.py runserver”會引發：ModuleNotFoundError: No module named 'dotenv'但在 ../mysite/venv/Scripts 中存在文件 dotenv.exe。還有 sobfolder ../venv/lib/site-packages/dotenv/ 。在 PyCharm-Settings-Project Interpreter 中的包列表中存在 python-dotenv 0.14.0好的。我嘗試通過 pip 安裝 dotenv，但它引發錯誤： C:\Users\User\mysite\mysite>pip install dotenvCollecting dotenv  Using cached https://files.pythonhosted.org/packages/e2/46/3754073706e31670eed18bfa8a879305b56a471db15f20523c2427b10078/dotenv-0.0.5.tar.gz    Complete output from command python setup.py egg_info:    Command "python setup.py egg_info" failed with error code 1 in C:\Temp\pip-wheel-4a1x88l2\distribute\    Traceback (most recent call last):      File "C:\Users\User\Anaconda3\lib\site-packages\setuptools\installer.py", line 126, in fetch_build_egg        subprocess.check_call(cmd)      File "C:\Users\User\Anaconda3\lib\subprocess.py", line 347, in check_call        raise CalledProcessError(retcode, cmd)    subprocess.CalledProcessError: Command '['C:\\Users\\User\\Anaconda3\\python.exe', '-m', 'pip', '--disable-pip-version-check', 'wheel', '--no-deps', '-w', 'C:\\Temp\\tmpz_ip4m3r', '--quiet', 'distribute']' returned non-zero exit status 1.    The above exception was the direct cause of the following exception:    Traceback (most recent call last):      File "<string>", line 1, in <module>      File "C:\Temp\pip-install-07by3weo\dotenv\setup.py", line 23, in <module>        scripts=['scripts/dotenv']      File "C:\Users\User\Anaconda3\lib\site-packages\setuptools\__init__.py", line 152, in setup        _install_setup_requires(attrs)      File "C:\Users\User\Anaconda3\lib\site-packages\setuptools\__init__.py", line 147, in _install_setup_requires        dist.fetch_build_eggs(dist.setup_requires)我嘗試這樣做：pip install --upgrade setuptools但沒有幫助怎么解決呢？
