问题 With the last update of Xcode to 9.3 running on High Sierra, I realized that Instruments is not working any more. When I try to open it from inside Xcode using Open Developer Tool > Instruments , I can see the template chooser dialog but as soon I pick one, a dialog appears: The document "Allocations.tracetemplate" could not be opened. Instruments cannot open files of this type. Allocations.tracetemplate could not be handled because Instruments cannot open files of this type. This happens

问题 I was attempting to install Django and pymc yesterday. After running into a lot of problems I decided to just re-install Python 2.7. I've done that but am now having problems import almost anything. I get a bunch of lines, the last of which are: File "c:\python27\lib\httplib.py", line 71, in <module> import socket File "c:\python27\lib\socket.py", line 47, in <module> import _socket ImportError: DLL load failed: The specified procedure could not be found.

问题 My Win 10 version of Visual Studio 2015 Community edition failed to load with error "cannot find one or more components .Please reinstall the application". I've tried repairing it but received nondescript errors so cancelled the repair (which also reported similar errors and eventually that 116 out 120 components had been repaired - iirc). I then tried an uninstall, but that crashed windows. On reboot, the VS 2015 uninstall options screen was displayed. Tried uninstall again but progress bar

问题 I accidentally removed /Library/Python on OS X Leopard. How can I reinstall that? 回答1: /Library/Python contains your python site-packages, which is the local software you've installed using commands like python setup.py install . The pieces here are third-party packages, not items installed by Apple - your actual Python installation is still safe in /System/Library/etc... In other words, the default OS leaves these directories mostly blank... nothing in there is critical (just a readme and a

问题 I've recently started teaching myself Ruby on Rails, and it's all going well except I'm looking to completely reinstall Ruby, Rails and Gem. I think I got a bit too excited at some point and deleted/modified some files or folders I shouldn't have, so I just want to get my system back to its original state so that I can reinstall the necessary Ruby, Rails and Gem bits. I've read in places that I can install something called rvm to do this, but right now I just want to keep my system as simple

问题 In WIX I'd like a feature to be installed and uninstalled normally but not to be touched during repair. I was not able to find a condition which would allow me to do this. My attempts has failed: the feature is reinstalled on repair (what I do not need) or is not uninstalled. This is a sample that I tried last: <Feature Id="aFeature" Title="A Features" Level="1"> <ComponentRef Id="aComponent" /> <Condition Level="0"> <![CDATA[WixUI_InstallMode="Repair"]]> </Condition> </Feature> What is the

问题 The scenario occurs when having to switch Installers (in this case Wise moving on). The situation of previous Inno Installers is handled by the Installer here. One inelegant way of telling whether a pre-Inno version is by absence of a reg key installed with Inno versions: Root: HKCU; Subkey: "Software\{#MyAppPublisher}\{#MyAppName}"; ... But the other more reliable way (assuming absence of above key by user CCleaner intervention or other) is interrogating the following: Software\Microsoft
