そこで、ターミナルを開き、デスクトップに cd して、次を実行します。
virtualenv test_env
次に、通常の環境で次のファイルを作成します。
/home/jesse/.local/lib/python2.6/site-packages/foo_package/__init__.py
このファイルには次の 1 行が含まれます。
print "importing from normal env"
test_env で作成します:
/home/jesse/Desktop/test_env/lib/python2.6/site-packages/foo_package/__init__.py
内容:
print "importing from test env"
ここで、ターミナルを開いて実行します。
$ /home/jesse/Desktop/test_env/bin/python
そして、次のようにします。
>>> import foo_package
どの出力:
importing from normal env
test_env からファイルをインポートしないのはなぜですか? それがvirtualenvの要点だと思いました。ここで何か不足していますか？

パスに何かが表示されているため、これは一歩前進したように見えますが、test_envまだ機能していません。私の現在の問題は、「/home/jesse/.local/lib/python2.6/site-packages」が「/home/jesse/Desktop/test_env/lib/python2.6/site-packages」の前のパスにあることだと思います'
編集 4: ロジャーは --no-site-packages オプションを使用して環境を作成することを提案しました。私はそれを試しました。同じ問題。

繰り返しますが、「.local」のサイトパッケージが「test_env」のサイトパッケージよりもパスの前に表示されることが問題のようです。
