<p>पाइप इंस्टॉल - अपग्रेड पाइप ब्रेक पाइप</p>

यह बग # 5432 "पाइप इंस्टॉल - अपग्रेड पाइप ब्रेक पाइप, अभी भी" के बहुत करीब दिखता है।

वातावरण

• पाइप संस्करण: पाइप 19.2.1 से /usr/local/lib/python3.7/site-packages/pip (पायथन 3.7)
• पायथन संस्करण: पायथन 3.7.4
• OS: MacOS Mojave 10.14.5 (18F132)

मैं Homebrew पैकेट मैनेजर का उपयोग करता हूं: Homebrew 2.1.89-07-23

विवरण

मूल brew install python स्थापना में, /usr/local/bin/pip3 एक सिमलिंक है। यह अंततः अपनी लक्ष्य फ़ाइल तक पहुँच जाता है: /usr/local/Cellar/python/3.7.4/bin/pip3 ।

brew info python मदद पर unversioned सिमलिंक उपयोग करने के लिए सिफारिश की गई है /usr/local/opt/python/libexec/bin : /usr/local/opt/python/libexec/bin/pip करने के लिए एक सिमलिंक है /usr/local/Cellar/python/3.7.4/bin/pip3 ।

pip install --upgrade pip एक नई फ़ाइल बनाता है /usr/local/bin/pip सिम्लिंक के लक्ष्य को अपडेट करने के बजाय, अर्थात /usr/local/Cellar/python/3.7.4/bin/pip3 । इसके अलावा, यह बाद वाली फ़ाइल अपडेट नहीं है।

PATH को /usr/local/opt/python/libexec/bin/pip होने से पहले /usr/local/bin/pip , सब कुछ विफल ...

अपेक्षित् व्यवहार

pip अपडेट करने पर, /usr/local/bin/pip को /usr/local/opt/python/libexec/bin/pip सिमलिंक होना चाहिए।

कैसे पुन: पेश करें

1. सभी pip साफ करें
   find -E /usr/local/ -type f -iregex '.*/pip[23]?' -print -delete

1. पुनर्स्थापित python के साथ Homebrew
brew reinstall python

2. / Usr / स्थानीय / बिन / पाइप *, आदि की स्थिति की जाँच करें और समान आई-नोड की तलाश करें।
   NB: ध्यान दें कि कोई /usr/local/bin/pip ।

ls -li /usr/local/bin/pip*
ls -li /usr/local/opt/python/libexec/bin/pip
ls -li /usr/local/opt/python/libexec/bin/../../bin/pip3
ls -li /usr/local/bin/../Cellar/python/3.7.4/bin/pip3

1. अपग्रेड pip के साथ pip
/usr/local/opt/python/libexec/bin/pip install --upgrade pip

2. ऊपर चरण 3 को फिर से करें।

3. कोशिश करें
   /usr/local/bin/pip --version

4. कोशिश करें
   /usr/local/opt/python/libexec/bin/pip --version

Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

If you need Homebrew's Python 2.7 run
  brew install python<strong i="24">@2</strong>

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages
