【问题描述】：
我通常使用 virtualenv 和 virtualenvwrapper 为我的项目创建虚拟环境。尝试使用以下命令创建新的虚拟环境：
mkvirtualenv -a . -p python3.7 venv
我收到以下错误消息：
Exception in thread Thread-1:
Traceback (most recent call last):

Setting project for cosine to /home/ubuntu/cosine_similarity
虚拟环境仍在创建中，正在运行：
pip -V
我明白了
pip 20.1 from /home/ubuntu/.local/lib/python3.6/site-packages/pip (python 3.6)
这与服务器上的默认 python 版本相关联，因此，我卸载了 python3.7，并在我的终端上运行 python3.7 得到：
Command 'python3.7' not found, but can be installed with:
sudo apt install python3.7-minimal
因此假设没有正确安装python3.7，我再次使用deadsnakes的ppa重新安装了它，如下所示：
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt install python3.7
但遗憾的是我仍然遇到同样的错误，我在虚拟环境之上使用诗歌并运行以下内容：（我有poetry.lock 文件）
poetry install
我收到以下错误消息：
[CalledProcessError]
Command '['/home/ubuntu/.cache/pypoetry/virtualenvs/cosine-similarity-SzdRNlpw-py3.7/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
如果有人能解释为什么会发生这种情况以及如何解决这个问题，那就太好了，谢谢。
[编辑]
在我使用-p python3.6 时添加更多信息，我没有收到任何此类权限错误，并且我的虚拟环境已成功创建。
有关更多信息，我使用上述 deadsnakes 的 ppa* 在系统上安装了 python3.8，然后尝试使用 python3.8 创建虚拟环境。
命令
mkvirutalenv -a . -p python3.8 venv2
stdout中的输出如下：

@aaron ：
ls -l /home/ubuntu/.local/share/virtualenv/seed-app-data的输出是total 4 drwxrwxr-x 5 ubuntu ubuntu 4096 May 15 23:51 v1.0.1，echo $USER的输出是ubuntu -
ls: cannot access '/home/ubuntu/.local/share/virtualenv/seed-app-data/v1.0.1/3.7/wheels/pip-20.0.2-py2.py3-none-any.whl': No such file or directory, 嗯...我想知道为什么 -
ls -l /home/ubuntu/.local/share/virtualenv/seed-app-data/v1.0.1/3.7/wheels显示total 2056 -rw-r--r-- 1 root root 1489786 May 14 10:02 pip-20.1-py2.py3-none-any.whl -rw-r--r-- 1 root root 582683 May 14 10:02 setuptools-46.1.3-py3-none-any.whl -rw-r--r-- 1 root root 26502 May 14 10:02 wheel-0.34.2-py2.py3-none-any.whl -
which python输出/usr/bin/python和python3.7 --version输出Python 3.7.9 -
所以只有
-p python3.7有错误？
