[英]python3.5 pip ImportError: cannot import name 'HTTPSHandler'
[英]ImportError: cannot import name HTTPSHandler using PIP
使用pip安裝python包時遇到HTTPSHandler錯誤,以下是堆棧跟蹤,

我曾經編輯 Modules/setup.dist 文件並取消注釋 SSL 代碼行並重建它,參考以下線程: http : //forums.opensuse.org/english/get-technical-help-here/applications/488962-opensuse -python-openssl-2.html
您可以獲得食譜的最新更新:
brew reinstall python
但是,如果您仍然遇到問題,例如,您可能已經升級了操作系統,那么您可能需要先獲取最新的 openssl。 您可以從以下位置檢查使用哪個版本和位置:
openssl version -a
which openssl
要獲取最新的 openssl:
brew update
brew install openssl
brew link --overwrite --dry-run openssl # safety first.
brew link openssl --overwrite
這可能會發出警告:
bash-4.3$ brew link --overwrite --dry-run openssl
Warning: Refusing to link: openssl Linking keg-only openssl means you may end up linking against the insecure, deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib
旁注:此警告意味着對於其他應用程序,您可能需要使用
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include
然后重新編譯python:
brew uninstall python
brew install python --with-brewed-openssl
或者對於python 3
brew uninstall python3
brew install python3 --with-brewed-openssl
如果需要 SSL 支持,則需要在構建 Python 之前安裝 OpenSSL 頭文件。 在 Debian 和 Ubuntu 上,它們位於一個名為libssl-dev
的包中。 您可能需要一些更多的依賴關系, 因為這里要注意。
這可能是由於升級到小牛隊造成的。 這是我修復它的方法。
#make a copy of the existing library, just in case
sudo cp /usr/bin/openssl /usr/bin/openssl.apple
# update openssl
brew update
brew install openssl
brew link --force openssl
# reload terminal paths
hash -r
brew uninstall python3
brew install python3 --with-brewed-openssl
brew uninstall python
brew install python --with-brewed-openssl
這個答案整合了我發現的所有 Stack Exchange 答案和評論,並且主要基於這個Apple Stack Exchange answer 。
我在 Mac OSX 上遇到了這個問題,即使在確認我的 PATH 等之后也是如此。
做了一個; pip卸載virtualenv然后安裝virtualenv,它現在似乎可以工作了。
當時我強迫 brew 鏈接 openssl,取消鏈接它,virtualenv 似乎仍然有效,但也許這是因為它最初是在我重新安裝時鏈接的。
對我來說這個問題的另一個症狀是,如果我進入我的 virtualenv 的 python 控制台並import ssl
它會出錯。 原來我的 virtualenv 沒有使用 python 的brew
版本,只是我機器上的默認安裝。 不知道為什么默認安裝突然停止工作,但這是我解決問題的方法:
rmvirtualenv myvirtualenv
brew update
brew reinstall python
mkvirtualenv -p /usr/local/Cellar/python/whatever_version_number/bin/python myvirtualenv
看來您的pip
需要HTTPSHandler
,它是SSL
庫的一部分。
操作系統
在 OS X 上,您應該在 Python 安裝期間鏈接 OpenSSL(參見: #14497 )。
對於 Python 2:
brew reinstall python --with-brewed-openssl
pip install --upgrade pip
對於 Python 3:
brew reinstall python3 --with-brewed-openssl
pip3 install --upgrade pip
您可以將多個 Python 實例放在一起,以列出它們運行:
brew list | grep ^python
或者通過ls -al /usr/local/lib/python*
列出您的版本。
我正在使用 Redhat 並遇到了同樣的問題。
我的解決方案是:
如果我沒有做第二步,當我重新編譯我的 python2.7 時,日志會說“無法構建模塊 _ssl”。
在許多情況下,這是由過時的 virtualenv 引起的,這里有一個重新生成 virtualenv 的腳本: https : //gist.github.com/WoLpH/fb98f7dc6ba6f05da2b8
只需將它復制到一個文件(上面的可下載鏈接)並像這樣執行它: zsh -e recreate_virtualenvs.sh <project_name>
#!/bin/zsh -e
if [ ! -d "$PROJECT_HOME" ]; then
echo 'Your $PROJECT_HOME needs to be defined'
echo 'http://virtualenvwrapper.readthedocs.org/en/latest/install.html#location-of-project-directories'
exit 1
fi
if [ "" = "$1" ]; then
echo "Usage: $0 <project_name>"
exit 1
fi
env="$1"
project_dir="$PROJECT_HOME/$1"
env_dir="$HOME/envs/$1"
function command_exists(){
type $1 2>/dev/null | grep -vq ' not found'
}
if command_exists workon; then
echo 'Getting virtualenvwrapper from environment'
# Workon exists, nothing to do :)
elif [ -x ~/bin/mount_workon ]; then
echo 'Using mount workon'
# Optional support for packaged project directories and virtualenvs using
# https://github.com/WoLpH/dotfiles/blob/master/bin/mount_workon
. ~/bin/mount_workon
mount_file "$project_dir"
mount_file "$env_dir"
elif command_exists virtualenvwrapper.sh; then
echo 'Using virtualenvwrapper'
. $(which virtualenvwrapper.sh)
fi
if ! command_exists workon; then
echo 'Virtualenvwrapper not found, please install it'
exit 1
fi
rmvirtualenv $env || true
echo "Recreating $env"
mkvirtualenv $env || true
workon "$env" || true
pip install virtualenv{,wrapper}
cd $project_dir
setvirtualenvproject
if [ -f setup.py ]; then
echo "Installing local package"
pip install -e .
fi
function install_requirements(){
# Installing requirements from given file, if it exists
if [ -f "$1" ]; then
echo "Installing requirements from $1"
pip install -r "$1"
fi
}
install_requirements requirements_test.txt
install_requirements requirements-test.txt
install_requirements requirements.txt
install_requirements test_requirements.txt
install_requirements test-requirements.txt
if [ -d docs ]; then
echo "Found docs, installing sphinx"
pip install sphinx{,-pypi-upload} py
fi
echo "Installing ipython"
pip install ipython
if [ -f tox.ini ]; then
deps=$(python -c "
parser=__import__('ConfigParser').ConfigParser();
parser.read('tox.ini');
print parser.get('testenv', 'deps').strip().replace('{toxinidir}/', '')")
echo "Found deps from tox.ini: $deps"
echo $deps | parallel -v --no-notice pip install {}
fi
if [ -f .travis.yml ]; then
echo "Found deps from travis:"
installs=$(grep 'pip install' .travis.yml | grep -v '\$' | sed -e 's/.*pip install/pip install/' | grep -v 'pip install . --use-mirrors' | sed -e 's/$/;/')
echo $installs
eval $installs
fi
deactivate
在 OSX 上,brew 一直拒絕鏈接到其 openssl 並出現以下錯誤:
15:27 $ brew link --force openssl
Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib
我終於能夠讓它與:
brew remove openssl
brew uninstall --force openssl
brew install openssl
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include
brew remove python
brew update
brew install python
首先檢查是否安裝 openssl-develop
sudo apt-get install libssl-dev
嘗試另一種方法重新安裝pip
sudo apt-get install python-setuptools
sudo easy_install pip
使用setuptools
安裝pip而不是用源碼安裝可能可以解決依賴問題。
剛剛安裝了ssl pyopenssl
pip install pyopenssl
