所以,关于问题 1: 答案是 pyenv install 目前不起作用。但是,只要安装了所需的pyenv version,脚本就会像魅力一样工作。所以你必须以不同的方式安装它(不是pyenv install)。
示例:
假设给你两个文件:
.python-vesion
.python-virtualenv
分别封装:3.8.2 和 test-venv。然后运行:
CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix bzip2)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include"
LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix zlib)/lib -L$(brew --prefix bzip2)/lib"
pyenv install --patch \$(head -n 1 .python-version) < <(curl -sSL https://github.com/python/cpython/commit/8ea6353.patch\?full_index\=1)
这应该会成功为 3.8.2 安装 pyenv。
那就这样吧:
pyenv virtualenv \$(head -n 1 .python-virtualenv)
如果你运行:
\$ pyenv virtualenvs
3.8.2/envs/test-venv (created from /Users/{your-pc-name}/.pyenv/versions/3.8.2)
test-venv (created from /Users/{your-pc-name}/.pyenv/versions/3.8.2)
您将确认新环境已创建。
关于问题 2:这是更新后的脚本:
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
# Automatic venv activation
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
export PYENV_VIRTUALENV_DISABLE_PROMPT=1
# Undo any existing alias for `cd`
unalias cd 2>/dev/null
# Method that verifies all requirements and activates the virtualenv
hasAndSetVirtualenv() {
# .python-version is mandatory for .python-virtualenv but not vice versa
if [ -f .python-virtualenv ]; then
if [ ! -f .python-version ]; then
echo "To use .python-virtualenv you need a .python-version"
return 1
fi
fi
# Check if pyenv has the Python version needed.
# If not (or pyenv not available) exit with code 1 and the respective instructions.
if [ -f .python-version ]; then
if [ -z "`which pyenv`" ]; then
echo "Install pyenv see https://github.com/yyuu/pyenv"
return 1
elif [ -n "`pyenv versions 2>&1 | grep 'not installed'`" ]; then
# Message "not installed" is automatically generated by `pyenv versions`
echo 'run "pyenv install"'
return 1
fi
fi
# Create and activate the virtualenv if all conditions above are successful
# Also, if virtualenv is already created, then just activate it.
if [ -f .python-virtualenv ]; then
VIRTUALENV_NAME="`cat .python-virtualenv`"
PYTHON_VERSION="`cat .python-version`"
MY_ENV=$PYENV_ROOT/versions/$PYTHON_VERSION/envs/$VIRTUALENV_NAME
([ -d $MY_ENV ] || virtualenv $MY_ENV -p `which python`) && \
source $MY_ENV/bin/activate
fi
}
pythonVirtualenvCd () {
# move to a folder + run the pyenv + virtualenv script
cd "$@" && hasAndSetVirtualenv
}
# Every time you move to a folder, run the pyenv + virtualenv script
alias cd="pythonVirtualenvCd"
