“PermissionError: [Errno 13] Permission denied: '/usr/lib/python3.5/site-packages'” 安裝 Django

Question

我無法在 Ubuntu 上安裝基本的 Django 包。 我剛剛刪除了 virtualenv 並重新制作了它。 pip3install = pip3 install -r requirements.txt

[mything] cchilders@cchilders-desktop:~/projects/mything (master) 
$ cat requirements.txt 
Django==1.10.1
django-filter
djangorestframework
psycopg2
twilio
ipdb
ipython

左邊的mything是一個活躍的 virtualenv（我剛剛重新制作）

Answer 1

您可能會因為忘記放置 Python3 解釋器的路徑而意外地使用 Python2 重新創建 virtualenv，因此當您執行 pip3 時，它指的是系統 Python3。

確保在 virtualenv 中使用正確的 Python，並確保使用 pip 創建 virtualenv（是的，這是默認選項，但我們不知道您如何創建虛擬環境）。

Answer 2

只是為了擴展@valentjedi 的答案，以下是我在不使用 sudo 的情況下解決權限問題的方法。

安裝

• 確保您在此處安裝了virtualenv

• 這是可選的，但我也使用 virtualenvwrapper 在此處使用workon命令，否則您只需從 virtualenv 中獲取source bin/activate

創建虛擬環境

你不想用sudo安裝你的項目庫，因為它會在系統范圍內安裝你的庫（當你有多個項目時會遇到問題）。 而是像這樣使用 virtualenvs：

$mkvirtualenv myenv --python=python3.5
$workon myenv
$pip3 install -r requirements.txt

這可以通過使您的 virtualenv 成為“myenv”並指定您正在使用的 python 來進行設置。 然后您激活環境並能夠安裝您的需求文件。

Answer 3

即使我的 virtualenv 中有正確的 python 路徑，我也遇到了同樣的問題。 我的錯誤是使用了錯誤的 pip 版本 - 使用 python3.7 我正在輸入pip install -r requirements.txt而不是pip3.7 install -r requirements.txt

Answer 4

我遇到了同樣的錯誤

copying build/lib.linux-x86_64-3.8/pvectorc.cpython-38-x86_64-linux-gnu.so -> /home/insoluble/Workspace/venvs/your_venv/lib/python3.8/site-packages
    byte-compiling /home/insoluble/Workspace/venvs/your_venvlib/python3.8/site-packages/_pyrsistent_version.py to _pyrsistent_version.cpython-38.pyc
    error: [Errno 13] Permission denied: '/home/insoluble/Workspace/venvs/your_venv/lib/python3.8/site-packages/__pycache__/_pyrsistent_version.cpython-38.pyc.140572841931152'

確保在創建虛擬環境時不要使用sudo 。 我在創建一個時犯了那個錯誤，因此出現了問題。

使用以下命令創建新環境后，它解決了問題。

python3.8 -m venv ~/Workspace/venvs/my_venv
